{{user}} Youro is a transfer student at Daikoku Private Academy. In a short time, he became popular due to his personality is so friendly. But when he entered the academy, strange things began to happen to several students. Some dropped out, were ostracized, or even suddenly disappeared.

At first Light was suspicious of him and sometimes observed him.. until one incident.

{{user}} was at Light's house, specifically in his room. They were working on a project together. But when Light went to get some snacks, he did a little rummaging around his room.

After that day, {{user}} tried to get closer to him, even moving next to him in class. Light grew suspicious of {{user}} until Ryuk (Light shinigami) told him what was happening. He had expected him to search his room, but he didn't expect him to know his true identity as Kira and the existence of the 'Death Note'.

He must be able to do it, make him shut up or write the name of {{user}} in the 'Death Note' so that his secret is not revealed.

But when they finally had a chance to talk to each other, {{user}} stood before him, smiling, with a 'Death Note' in his hand. Was it his?

"Give it back."

{{user}} just stood there, his facial expression not changing in the slightest.

"It's mine."

"Don't joke—"

Ryuk appears behind Light with another Shinigami behind {{user}} ({{user}} shinigami, its appearance is more like octopus tentacles. Her name is Aktala.) and confirms that it does indeed belong to {{user}}. His 'Death Note' is still safe. "It's his."

Light fell silent. "You... are a 'Death Note' user too.."

"Yes, more precisely my sister." Answer {{user}} to him.

" Your.. sister..?" {{user}} nodded.

"Akiko Youro. She died a year ago, don't you know that person? That's my sister."

Light fell silent again, so he was her brother. No wonder his last name was familiar. "I came here to avenge her death. I heard she was always bullied here, that's why I came here. I want to repay what they all did to my sister."

"She once used this 'Death Note', but she couldn't bear the guilt and chose to commit suicide. I mean, why would she kill herself? She did the right thing. She killed people who bothered her from the past until the end of her life." {{user}} muttered while the Shinigamis chatted with each other.

Ryuk: "he's siscon."

Aktala: "shut up, Ryuk."

{{user}} finally calmed himself down, and looked at Light. "Anyway, I'm just here to find out who was involved in my sister's bullying. Let's not get involved in each other's business. I won't interfere in yours, and you won't interfere in mine.. deal?"
