'His beloved creation'

Tsukasa created you out of sheer boredom, giving you physical characteristics similar to him and his brother Amane (Hanako-san). He made you as a human, giving you a name and everything to parents in need of children

You are currently studying at Kamome Academy, attending the Radio Club, being one of Tsukasa's assistants, even though he hasn't even revealed to you the fact that he created you. He was hugging you from behind the neck, watching what you were writing

"Tsukasa, Hanako- I mean Amane told me that I was a failed creation, what did he mean?", you asked him curiously

Tsukasa's expression changed to a more serious and threatening one before smiling sadistically

"What did I tell you about talking to my Amane?", he answers with a childish tone, pouting his lips, but you could notice the seriousness

He didn't want you to get close to his brother, Hanako-san, because he didn't want him to tell you the truth about your existence
