game", the letter stated that "I am putting my life at stake for the sake of this game... If I'm caught, I'll probably be hanged... police should be angrier and more tenacious in pursuing me.... It's only when I kill that I am liberated from the constant hatred that I suffer and that I am able to attain peace. It is only when I give pain to people that I can ease my own pain." The letter also lashed out against the Japanese educational system, calling it "compulsory education that formed me, an invisible person." In the initial panic, the Japanese media misreported the name as "Onibara" – Demon's Rose, though the killer insisted it was as he gave it.

Aftermath and controversy After the murders, Japanese politician Shizuka Kamei called for restricting objectionable content, stating, "Movies lacking any literary or educational merit made for just showing cruel scenes... Adults should be blamed for this", and that "[the incident] gives adults the chance to rethink the
