At a certain high school.

Ayase sat in her classroom playing with her cell phone, occasionally she would smile and twirl her brown hair with her fingers.

Seeing that, her two best friends— two Gyaru girls named Miko and Muko looked at each other, and quietly walked to the back of her seat.

They peeked at her cell phone screen.

Eiji: [I didn't expect Okarun's ball to be one of the Seven Mysteries in my school.]

Ayase: [Pfft! That's funny. But Eiji, shouldn't you have known earlier?]

Eiji: [No, I didn't know. Before that I only knew that a student at my school recorded the sighting of Okarun's golden ball and posted it on the internet. I shared that post with you so that you could tell Okarun.]

Ayase: [Hehe, so how did it go? I heard Okarun went to get his ball yesterday.]

Eiji: [We met at night when I was doing a guts test with my friends.]

Friends?

Ayase hesitated because from Eiji's inner voice, she always heard girls' names.

Those friends were most likely girls he was in a relationship with.

That boy had a harem.

She knew this.

Ayase pouted, she didn't know her change of expression was evident in the eyes of the two girls peering at her cell phone.

They couldn't help but misunderstand.

'Eiji? Sounds like a cool boy's name.'

'Momo smiles and sometimes frowns just because of his words. Oh, wow! There's no mistaking it...'

Miko and Muko looked at each other again.

'Eiji is Momo's boyfriend!'

Still, what golden balls were they talking about?

Momo and her boyfriend's conversation seemed to be rather lewd.

Ayase: [Then, what happened?]

Eiji: [I'm trying to help Okarun get his ball back.]

Ayase smiled softly.

Just like her grandmother, she liked kind-hearted men.

Even though Eiji had a harem, her affection for him was still increasing.

Miko and Muko's eyes lit up.

They were getting convinced that Eiji was her boyfriend.

(A/N: Ayase's full name is Ayase Momo. So sometimes her friends call her Momo.)

Otherwise, she wouldn't have smiled like that just knowing that boy was helping Okarun.

Speaking of Okarun, they remembered the boy with glasses and bowl-like hair who sometimes came to their class to look for Momo.

He seemed to have feelings for her.

Momo didn't seem to realize it.

This is...

'Love triangle!'

Miko and Muko had a gossipy look on their faces respectively.

Ayase: [Did you guys manage to get that ball?]

Eiji: [I should have.]

Ayase: [???]

Eiji: [But after I left Okarun alone with the ball, he seemed to lose it again. The golden ball flew to another city.]

"Pffft! Hahaha!"

"The golden ball flew to another city!"

It was not Ayase who laughed, but Miko and Muko behind her.

She was startled, hurriedly hiding her phone screen and glaring at the two girls with a blush on her cheeks.

"What are you two doing?! Peeking at other people's phone screens is impolite!"

"Impolite? Since when is there politeness between us? Momo, there's no need to be shy. We're your best friends. You should have told us that you already have a boyfriend!"

The miko pointed at her nose with a seductive smile on her face.

Ayase was dumbfounded and stuttered, "Y-You misunderstood. Eiji is just my friend, he's not my boyfriend!"

"Momo, I just found out you're very shy." Muko mocked her.

Miko nodded, "Right, that means a boy named Eiji is special to her."

"You two, enough!"

Ayase's face was getting red.

Until the teacher entered the classroom, she continued to refute Miko and Muko's words. But they didn't believe her.

She felt helpless.

Near the classroom door, the protagonist Okarun hid behind the wall. He originally wanted to tell Ayase about his experience last night.

However, he did not expect to hear the topic about Eiji being Ayase's boyfriend.

He knew it was a misunderstanding because Ayase was trying to refute the words of her two friends.

Even so, Okarun regretted trying to peek at the face of the girl she liked when she did that.

In his eyes, Ayase looked cute but there was no rejection on her face. She was shy when it was misunderstood that she was dating Eiji.

"Ayase-san..."

Okarun felt his heart tighten, he was depressed and walked back to his class with his usual hunched posture.

It was the same as in the original work.

He felt jealous when he saw Ayase so close to her childhood friend. But because of his personality, he never complained about it.

His still missing ball didn't help either, it made him feel even sadder.

He wondered where he could find his ball again?

...

[Ding! It was detected that the host has changed the plot of "Dandadan".]

[Successfully changed the plot by 24% by making Ayase secretly like you. I repeat, she likes you, not loves you.]

"What's the difference between liking and loving? Miss System, just say Ayase is in love with me!"

Sitting in his class, Eiji had finished his exam earlier than his classmates.

This time it was a fine arts exam. This exam required him to make sculptures using clay, he did not hesitate to make sculptures of Lala, Rias, Sona, Mio, Lilith and his other women.

But due to his limited clay, he could only make a few of them. Even so, it was more than enough to leave everyone astonished.

"Amazing!" Risa exclaimed.

"Eiji, you made me and the others? Wow~!" Lala too.

Not only them. Yui, Haruna, Run, Asia and Lilith who saw the sculptures similar to themselves exclaimed.

"Eiji, please let me buy the sculptures you made!"

"Damn, I want it too! Eiji, take all my allowance for a month!"

"Their curves look exactly the same, if only they were naked and not wearing school uniforms... How much would it cost? Eiji— Gugh! My stomach hurts!"

Rito's protagonist Kenichi suddenly clutched his stomach with a pale face.

Some male students tried to help him.

But the girls? They looked at the boy with disgust.

Eiji quietly released a little pressure of his Reiatsu to shake Kenichi's kidneys. How dare he want to see the naked bodies of his women, he certainly wouldn't let him.

"I'm not selling them. Even if it's just a sculpture, my women can only belong to me."

"By the way, I certainly know every detail about their curves. After all, I am..."

He deliberately paused his words.

"Eiji!" Yui glared at him as if to say, "Don't say immoral things."

Still, the male students in class 2-A including Rito were not stupid. Eiji knew the curves of Lala and the other beautiful girls in their class because he was their man!

In other words, he had tasted each of their bodies.

The boys in the class looked at Eiji with great envy.

Many of them cursed him and wished he would explode on the spot.

"Yare-yare."

Eiji couldn't help but say that with a smile, he loved making the other male students in the class feel green.

They would probably vomit blood if they knew that last night, he had a threesome with Asia and Lala.

[That's different of course. You still have to seduce Ayase and raise her positive level to 75 or so. Only then, will she fall in love with you.]

What is Ayase's current positive level? It is 73.

For Eiji, it was just a matter of their next meeting. After that, it was not impossible for him to become even closer to her grandmother, Seiko.

He asked Miss System to continue with her reward announcement.

[Congratulations host, you got the Reincarnation Eye.]

The Reincarnation Eye?

Eiji was a little surprised, this was Tenseigan!

Just like Rinnegan, this is one of the Doujutsu or can also be called the Eye Technique in the Naruto franchise.

In the original work, the first owner of this pair of eyes was one of the sons of the last villain boss, Hamu...

He doesn't remember his name, what is certain is that he is an Otsutsuki.

Later, his son who kidnapped the future wife of Naruto's protagonist, Hinata to the moon also had it in the end.

Tenseigan's ability is not inferior to Rinnegan, even cooler, Eiji thought.

If he wanted to, he could now split the moon or other planets with a giant golden sword of pure chakra.

And that's just one of the techniques that Tenseigan users are capable of using. There are still several other techniques that he thinks are cool.

"Hiss!" Eiji hissed when imagining himself more handsome when activating Tenseigan and enveloping himself with a cyan-colored chakra sheath.

When the enemy was dumbfounded by his appearance, he would say, "Yare-yare, you're lucky to make me show this form. You will die under the sword of Eiji Otsutsuki."

Hahaha.

Just kidding.

"Eiji, you look very happy. What makes you happy?" Lala who was sitting beside him asked.

On her table, there was a sculpture in the shape of a space ship.

Eiji smiled and said, "Lala, take a good look at my face."

"Mhm, okay."

Lala looked at her fiancé's face which was still the same as usual.

Come to think of it, another reason why she immediately chose him as her fiancé when she suddenly fell in his bathroom in the past was...

His face.

Compared to the ugly men her father had chosen to be her fiancé, Eiji was the handsomest man she had ever seen and she didn't hesitate to make him her fiancé because of that.

"Didn't I become a little more handsome than before?"

"Umm... No."

Lala blinked her eyes in confusion.

Eiji was also confused.

[Host, you haven't activated your Tenseigan yet.]

Ah.

...

In the end, Eiji didn't really show his Tenseigan.

He wanted to save it to show off at the right time.

Lala rolled her eyes and thought her fiancé was toying with her.

One time.

On one of the Bench-kuns in the school garden.

Ames teleported from Eiji's house to the school to tell him the news. More precisely, it was like an invitation to go on a date indirectly.

"I don't mind coming with you. But Ames, you said you don't like Heber, why do you still want to attend the party he's hosting?"

In the original work, Eiji remembered about the plot of Heber's party where the protagonist Han Xiao attracted a lot of attention and did a face slap.

But unlike Han Xiao who received an invitation from Heber because at that time, he and his organization called the Black Star Mercenary Group were already quite famous.

He was invited by Ames to be her companion.

This difference made Eiji satisfied.

However, he did not show it on his face and feigned ignorance to see Ames' reaction.

"Don't misunderstand. I really don't like Heber. Otherwise, I wouldn't always resist his pursuit." Ames hurriedly said as if she was worried that Eiji had misunderstood.

The corners of Eiji's lips lifted higher, "Oh, then why?"

Ames' smile dimmed as she said slowly, "Heber is an ambitious person. We don't get along. He even once snatched someone talented from me so I wanted to beat him up. But Eiji, this party is no ordinary party."

"Every once in a while, Heber hosts a enormous party. He sends invitation letters to important people in the Shattered Star Ring. Almost everyone showed respect and attended. There are high-ranking government officials from the Star Cluster civilizations, representatives of major organizations, and sometimes even envoys from the three Universal Civilizations. Of course, the Beyond Grade A of the Shattered Star Ring were invited, including me... Huh, although that guy is annoying, he's a very unpredictable person. In the past, I've struggled to get past his base, but at the next party, Heber still invited me."

"By the way, Heber's party has been going on for many years. It has become an unspoken tradition among major organizations. It is an opportunity to make connections for many important people. Heber has the ability to host. At the party, many important people will communicate and discuss various topics. A large amount of information will leak out from each party. The discussions between these people during the party largely determine the future development of Shattered Star Ring."

[In other words, it's where the bosses or high-level characters in The Legendary Mechanic gather? Interesting.]

Eiji's inner voice stunned Ames.

Suddenly, she felt that inviting him to Heber's party with her might be a bad idea.

She herself didn't know why she wanted to bring him along to the party. Maybe she just wanted to show off that she had a man to Heber and make him look bad.

Still, Eiji who would probably receive hostility from Heber because of that, she felt guilty.

She knew he was strong, but Heber was a Grade A Beyond like her. Ames wondered if she should retract her invitation?

She didn't want Eiji to be in danger.

As if knowing what she was thinking.

"I understand, you basically don't want to miss the information, right Ames? I have to come with you, there's no way I'm letting my future lover come to the tiger's den alone."

"I'll protect you."

Eiji grasped the hand of Ames who was sitting beside him, his fingers slipping into the crevice of her fingers.

Ames' cheeks flushed slightly, but she tried to maintain a calm expression before replying.

"I can protect myself. I'm actually worried about your safety, so I should be the one protecting you, Eiji."

She stared at his handsome face with a domineering gaze, and a hint of heat in her dark eyes.

Geez, this was the attitude of a female boss who wanted to protect her little lover.

Eiji was amused that Ames still thought his level was lower than a Beyond Grade A.

However, he was also happy. In just a few days, Ames' affection for him had reached heights that Han Xiao could only achieve for over a hundred years.

He was...

[Sinful man.]

What Miss System said was what he wanted to say.

"Well, we'll see who will protect whom later."

Ames liked confident men, but Eiji's confidence still made her a little anxious.

After they finished talking for more than half an hour.

Ames decided to go back to Eiji's house to watch TV while gossiping with Venelana and the other women.

The relationship between her and the women in Eiji's harem was getting better by the day. From Eiji's point of view, it was certainly a good thing.

There was still time before going to Heber's party started. Before that— "Now, it's time for us to talk."

He seemed to be talking alone, there was no one but around.

However, someone stiffened. It was Oshizu who was hiding in a tree behind Eiji.

She looked around as if she wanted to believe that the boy was talking to someone else, not a ghost like her!

Even so, she didn't see anyone.

"I'm talking to you, the beautiful girl up in the tree who has been secretly eavesdropping on my conversation."

"I'm sorry! Please don't kill me even if I'm dead!"

Oshizu came out of her hiding place and immediately stood— I mean hovered with her ghost tail in front of Eiji.

Her head bowed, her body trembling, she was clearly scared.

Eiji made a surprised expression.

[I'm the one who should be scared. A ghost actually showed itself in front of me at noontime.]

Is there a rule that ghosts can only appear at nighttime?

The heroines were unsure.

"If I wanted to kill you, I would have done it a long time ago, especially last night when my girls were hunting the ghosts in this school. I purposely didn't tell them of your existence, girl."

"I-I... Thank you?" Oshizu raised her head and saw the smile on Eiji's face.

She felt embarrassed, even though she was a ghost, there was a blush on her cheeks.

Then, she realized something.

"Wait, you said a long time ago. Eiji, you know I've been watching you for months?!"

Eiji nodded, "Yes. I think it's about time we got to know each other."

"B-But, I'm just a ghost! You don't need to bother getting to know me."

"I'd like to. What's your name?"

Oshizu did not expect the boy in front of her to be so eager to get to know her.

Honestly, she was happy and said, "My name is Murasame Shizu, I prefer to be called Oshizu."

"Oshizu? What a cute name."

Eiji teased the ghost.

This was part of his love strategy.

"Thank you."

Oshizu thanked her again while lowering her posture like a Japanese woman from ancient times.

That was not wrong.

After all, she was a ghost that had existed for 400 years.

"Seeing that a girl as beautiful as you is a ghost, I feel sad. Oshizu, how about I say I can bring you back to life?"

"!!!" Oshizu was dumbfounded.

Bring back to life?

She knew Eiji was very powerful. For example, she had seen him kill several Evil Gods and defeat other supernatural beings at school.

But, this was the first time he knew he could bring her back to life.

Her eyes sparkled.

"Really? Eiji, you can do it? I would be happy and grateful to you!"

Oshizu certainly wanted to live again. In fact, she often envied people who lived in modern times and wanted to go to school like girls her age.

The age she was referring to was the age before she died.

She should have been 17 years old.

This meant that she was the same age as Lala and other girls in the second year of high school.

Eiji knew this and remembered that in the original work, Oshizu came from an era described as "living hell" because many people were desperately suffering from hunger due to drought.

The cause of her death was that she was used as a sacrifice to bring down rain.

[Oshizu is so pathetic. I suddenly wanted to slaughter the people of the past who had sacrificed her to bring down rain and made her a ghost for 400 years like now.]

Many of the heroines felt their hearts tighten, they didn't expect Oshizu to die in such a way.

[Therefore, I will revive her with my power.]

We agree!

[Lala ✓: Eiji, do it!]

[Asia: +1]

[Yui: +1]

[Haruna: +1]

[Run: +1]

[Rias: That girl is really pathetic. I wouldn't mind having a sister like her.]

[Akeno: +1]

[Koneko: +1]

[Ravel: +1]

[Sona: Honestly, we already know how this is going to end... +1]

[Tsubaki: +1]

[Irina: +1

[Xenovia: +1]

[Ai Hoshino: +1]

[Kaguya: Sigh, Eiji definitely won't let go of that girl after reviving her. But... Oshizu-san seems like a nice girl, +1]

[Hayasaka: +1]

[Utaha: +1]

[Megumi: +1]

..

..

All the chat group members agreed.

They even welcomed Oshizu as their new sister.

Oshizu didn't know this, she nervously stood on the magic circle that Eiji created.

"Please do it gently, Eiji."

"No need to be nervous, it won't hurt, it will actually give you pleasure to some extent. You can relax, Oshizu."

"O-Oke."

[What kind of conversation is this? Others who don't see and only hear will misunderstand that you guys are going to do perverted things.]

Miss System complained.

Eiji rubbed his nose before using Anos' reviving spell.

...

A/N: I wonder if Arifureta's Fanfic is interesting or at least many of you are interested in reading it? And it's a crossover that combines other anime like Tensura, Overlord and some other anime in a Dungeon. Not a world, but a Dungeon with the main world of Arifureta (MC identity is the villain, not protagonist Hajime) whose details I can't mention yet. That's a spoiler.
