The Delinquent Student is the Savior of the World

"Kuromori-kun, good afternoon~"

Seeing Haruto, the eyes of both girls sparkled.

A soft and bright smile suddenly appeared on Ichika's face, like layers of blooming begonias swaying in the spring breeze.

Nino put down her phone and stared at Haruto with bright eyes, a flickering light moving in her gaze.

However, after seeing Miku hurriedly come in front of Haruto, her mood suddenly became sour, and she then glared at him with an unfriendly look.

"Good afternoon." Haruto approached and said, "Be careful on your way home."

Nino placed her hands on her hips and stared at him with wide eyes: "Hmph, we're not kids, so we don't need you to remind us~"

"Kuromori-kun can come back with us~" Ichika said with a smile.

"Next time."

Haruto approached Nino, squeezed the girl's hand without leaving a mark, and said, "I have something to do today, so I'm leaving first."

Nino's cheeks felt a bit warm, but she took the initiative to gently scratch the palm of her hand with her fingers.

For some reason, she found herself very nervous and excited with such a secret and intimate interaction.

"Kuromori-kun, goodbye."

"Um."

Haruto waved his hand, then turned and left.

Next, he would catch his little sister, Nanako, who was a bit spoiled. If she told the truth, everything would be easy.

If Nanako still refused, he would lock her in a small dark room.

Well, that could be a consideration.

Soon, Haruto arrived at the only path to Nanako. He walked to the vending machine and bought two bottles of Coke.

Coke can easily add weight if you drink too much. Although sugar-free Coke is now available, it lacks the taste of regular Coke.

Therefore, Coke remains the best-selling drink in the world.

And it is known as the happy water for fat households.

Under normal circumstances, their mother would certainly not allow Nanako to drink Coke. After all, Nanako was still young and didn't know how to control herself. She ate delicious food as much as she could, and the same went for drinking Coke.

So it was no problem.

But this time, Haruto planned to use Coke and snacks to win over Nanako.

He thought the chances were quite high.

"Apart from Coke, Nanako also likes to eat potato chips. Forget about the chips; there's a food street not far from here. I'll take her straight there."

Haruto didn't believe that his greedy and stingy little sister could resist.

"Ayako, hurry up!"

At this moment, a sharp, sweet voice sounded.

On the road, three girls, one in front and two behind, quickly ran towards this side.

The fastest among them was Nanako. As for the other two, one of them was the mischievous girl who had once offered to provide bed-warming services, Kagura Ayako.

The reason she was described as a "mischievous girl" was that Ayako had not yet become a naughty girl and had not developed any bad habits.

The other was a girl who had suddenly joined the class, named Tomoe Mami.

With her smooth and enchanting golden hair, beautiful face, and graceful words and deeds, she resembled a noble girl.

Of course, all of this didn't matter.

What mattered was that Mami looked quite mature and didn't look like a girl of Nanako's age at all.

If a senior from Sobu High School saw Mami, she might suffer severe trauma.

"Nana-chan, you're running too fast!"

"Nana-chan, slow down, be careful not to fall."

"I won't fall!"

Nanako placed her hands on her hips, lifted her head proudly, and her two pigtails swayed gently behind her back.

"Ayako, Mami, you're so mean! This is unacceptable, so for the sake of our Mysterious Research Club activities."

"I've decided! Starting today, we will start special training for you!"

Haruto fell silent and then walked closer.

"Hey! That's Onii-chan!"

Ayako, out of breath, suddenly quickened her pace as her eyes sparkled.

"Onii-chan?"

Mami was stunned, her eyes focused on Haruto.

The last time she saw him on the overpass, he was next to Nanako. Then she learned that the other party was Nanako's stepbrother, and he was the one who brought Nanako to find her.

"Onii-chan, good afternoon~"

Ayako ran towards Haruto, raised her face, and showed a very sweet and cute smile.

"Ayako, good afternoon."

"Nii-san, why are you here?"

Seeing Haruto, Nanako's eyes sparkled, and she ran, "Nii-san, did you buy Coke for Nanako?"

"Well, here it is."

"Thank you, Nii-san, Nanako likes you the most."

Nanako took the Coke but didn't drink it; instead, she extended her hand: "Nii-san, Ayako and Mami haven't had any yet."

Mami waved her hand quickly: "Nana-chan, I don't need it."

"NO!"

Nanako reasoned: "Mami, you are the brain of our club, and we mustn't treat you poorly."

Seeing Mami staring at him silently, Haruto turned and said, "I'm Nanako's brother, Kuromori Haruto; we met last time."

"Ah~ senpai, I'm Tomoe Mami, please take care of me."

"Don't be nervous; I won't eat people."

"Hmm~"

Mami's face turned red, facing his sudden teasing; she felt a little confused for a moment.

Nanako puffed up her cheeks: "Baka Nii-san, don't tease Mami."

"I'm not."

Haruto denied it. He just saw Mami looking a bit nervous, so he was only trying to ease the atmosphere.

But anyway, he didn't know Mami well, so Haruto didn't say anything more but took out a thousand yen and handed it to Nanako.

"This is for you; hurry up and buy something."

"Hmph~"

After walking for a while, Ayako and Mami said goodbye and went home.

At this moment, they arrived near the food court. The tempting aroma of food wafted in the air.

Nanako swallowed hard, involuntarily tugging at Haruto's clothes, covering her stomach, and said pitifully: "Onii-chan, Nanako is hungry."

As she acted like a spoiled child, she called him Onii-chan, and when she didn't act like a spoiled child, she called him Nii-san.

But this time, Haruto didn't refuse.

"What do you want to eat?"

Nanako's eyes sparkled, and she immediately said: "Onii-chan, Nanako wants to eat strawberry daifuku, takoyaki, and croquettes."

"Sure."

Haruto immediately bought strawberry daifuku, takoyaki, and croquettes. He even bought more tamagoyaki, crepes, and milk tea.

"Nanako, come here first and let me hug you."

"Eh?"
