Kirino and Ruri snorted coldly, turned their heads away, looking like they couldn't stand each other.

"This... they're clearly arguing, aren't they?" Kyousuke had a headache.

"The premise of arguing is that it happens after both parties have established a certain relationship." Tenya borrowed the line from a certain dead-eyed character.

"So that's it, Tenya makes sense." Saori adjusted her glasses, then gave a thumbs-up.

"Huh? Is something wrong with my eyes, or are you guys mistaken?" Kyousuke looked incredulous.

"Kōsaka, look, they're different from just now, they're so energetic." Saori said with a smile.

"Uh, it seems that way..."

"But even though they just met, it's amazing they can argue so fiercely." Kyousuke's lips twitched.

"This is easy to understand. It's because both sides are discussing things they truly like, and it's impossible to hide it. Tenya thinks so too, right?" Saori looked at Tenya expectantly.

"Oh? Saori understands me well." Tenya blinked at her.

"Eh! I only understand a little bit..." Saori twisted her body shyly.

This guy...

He is a master at picking up girls!

Kyousuke felt a hidden sense of vigilance, but as long as the other party didn't hit on his sister, it was fine.

"It's rare to come to Akihabara, let's look around."

Tenya's suggestion immediately made the two girls, who were still fiercely clashing, cease their argument.

After leaving the cafe, they went to a nearby anime goods store.

Kirino excitedly bought a huge pile of goods, looking like she had money to spare.

Ruri, on the other hand, carefully selected only one or two items.

"Black Cat, there's no need to be so tight with the budget, right?"

"Didn't you get hundreds of thousands from the previous game's sales?" Tenya asked.

"Most of the money has been saved."

"There will be many places where money will be needed in the future."

"Besides, these goods are more cost-effective if bought at a discount after the season is over."

Ruri wasn't old, but she had already learned to be thrifty.

"Game sales?"

"May I be so bold as to ask, do Black Cat and Tenya make games themselves?" Saori looked curious.

"Yes."

"I had a game development club in high school, and I met Black Cat when I was looking for programming outsourcing on the forum." Tenya explained simply.

"Wow, that's amazing."

"A high school student can lead the development of a game."

"Look at them, you useless older brother."

Kirino first looked at Tenya with admiration, then turned her head and stepped on her older brother's foot in disdain.

"Uh..."

Kyousuke instantly became speechless.

"I am very interested in the games made by Tenya and Black Cat, please be sure to send me the link, I want to buy three copies." Saori held Ruri's hand with anticipation.

"Then, alright..."

Ruri's lips curved slightly upwards, feeling a little proud in her heart.

"I..."

Kirino hesitated, wanting to speak but stopping.

In fact, she was also very interested in the game made by the other party. But just thinking about how long she had been clashing with this chuunibyou, it was really hard to voice her request.

Tenya saw through her thoughts, so he took the initiative to say, "Kirino, is it convenient to add a contact method? I can send you the game link."

"Of course you can. I should say it's my honor." Kirino looked flattered and quickly pulled out her phone from her pocket.

Seeing his sister add a handsome guy as a friend, Kyousuke's face turned green.

...

"Oh dear. I accidentally forgot the time, it's already so late."

"It's all because you played too wildly."

"This is my first time coming to Akihabara."

The group went around from morning till night, almost touring the entire Akihabara.

"Sigh... It's so tiring shopping with girls."

Kyousuke's arms and neck were all covered with various goods his sister had frantically bought.

"Kōsaka-kun, that's rude of you. Shopping with cute girls, and three of them at that, you should be happy." Tenya patted his shoulder meaningfully.

"Tsk. Lame. That's why you're unpopular." Kirino clicked her tongue, looking at her older brother with disdain.

"You can blame me for this too?" Kyousuke instantly turned speechless.

"Ah! My driver is here to pick me up." Saori glanced at her phone.

"Driver?"

"Is Saori a young lady from a wealthy family?"

Everyone looked surprised.

"Well. Don't mind these details."

"Black Cat, Tenya, and also Kiririn and Kōsaka, goodbye." Saori waved goodbye to everyone.

"Black Cat, it's so late, it's not safe for you to walk alone. I'll see you off."

After Tenya finished speaking, he took the shopping bag from Ruri's hand without allowing any refusal, making the latter unable to refuse.

"Look at him, how strong his manly power is." Kirino looked envious.

"Aren't I escorting you home right now too?" Kyousuke expressed his disagreement.

"Look at your listless, pathetic appearance."

"If you really encountered bad guys, where would you get the strength to protect your sister?"

Kirino already had many complaints about Kyousuke, and now with Tenya as a comparison, the difference between the two was simply too great.

Subway station.

Six thirty was the peak hour for commuting, and the flow of people was quite dense.

For Ruri, who had social anxiety, the feeling of oppression immediately surged. Cold sweat streamed down her forehead, and her breathing became rapid.

"Black Cat, are you alright?" Tenya took her hand.

"Mm. Today, magic power has been consumed a little excessively." Ruri sighed deeply.

"Feel free to rely on me."

Tenya pulled Ruri into his arms, wrapping his hands around her small figure.

Ruri's face was red, and she whispered like a mosquito, "The contract has come a step closer."

...

After safely escorting Ruri home, Tenya was invited to stay for a meal.

A pleasant day came to a perfect end.

However, the Kōsaka family wasn't so lucky.

When the Kōsaka siblings returned home, they happened to run into their strict gather.

Kyousuke, feeling guilty, accidentally knocked over the shopping bag in his hand, causing a large pile of manga books and game discs to fall to the ground.

Among them were contents involving R-18, which made Daisuke, who came from a certain profession, furious.

He not only severely criticized the siblings, but also claimed that otaku culture was a harmful tumor to society.

A classic case of generalizing everyone.

Kirino looked wronged and tearful, saying that this was just her personal hobby and didn't affect anyone else.

Daisuke had a strong attitude and forcibly confiscated all of Kirino's manga books and game discs.

During this time, Kyousuke tried to reason with him, but was knocked down by a single punch.
