Third person POV
"What were you doing to Hachi-kun?" Akira said to Isao while walking towards him.
"Oh, um…" Isao tried to come up with an excuse.
But Akira knew what was going on and kicked the syringe out of Isao's right hand.
Meanwhile, Riho and Aiko took Isao's backpack and inspected it for any suspicious items.
Then, the two girls found more syringes of suspicious liquids and a notebook containing the notes of the liquids' composition, effects, and side effects. Aiko and Riho were shocked and looked at Isao.
"You…"
"You psycho!"
Isao was shocked and tried to explain.
But unfortunately, one classmate who came with Akira and the others, a Korean-Japanese boy named Kang-Dae Yamada, said to Isao boldly, "We knew what you did to Hachi back then, and you have no right to treat him like that!" Isao was upset and tried to get away with it, but Akira and Kang-Dae tackled him to the floor, while Riho and Aiko helped Hachi get up.
"Get off of me!" Isao scowled at the two boys.
"Nope!" Kang-Dae responded back while holding Isao's arms.
"Yeah!" Akira added.
Not long after, some teachers and students heard the commotion and went there, only to see what was going on. "What's going on here?" asked one of the teachers. Aiko and Riho then showed the syringes Isao had. That teacher and the others were shocked, and Hachi revealed, "Isao-san is trying to experiment on me!"
"Yes, Isao is from Kara Tech," Akira added.
Isao was shocked again and looked at Akira and Kang-Dae. "How did you know that?"
"Someone told me about it…" Akira replied back, hiding the fact that Kei was the one who did it.
Isao was a bit frustrated, yet he was caught and taken to the principal's office.
There, the principal was shocked, and Aiko and Riho showed Isao's belongings as well as his notebook detailing the contents of the syringes. Kang-Dae also revealed that Isao had been bullying other students, and he had video evidence in his phone. Furthermore, Akira revealed to the principal about Isao's true intentions of being in the school and showed a notepad of Isao that details Hachi's movements and activities.
Because of all these, the principal decided to expel Isao out of the school, much to Isao's shock and disappointment. And so, Isao was now expelled from school, and Isao himself left the school.
