Supuestamente el ultimo post del asesino este en 2chan o uno de esos


​
Y estos son rumores, más tarde si puedo los traduzco:

Cita:Basically, unhinged ranting about his waifu from the TV show getting a boyfriend?

​

Edit: There's a rumor that this was バリサク君, a known Train Otaku. Supposedly the same person who posted the above 2ch (5ch?) post. Theory I heard from a 2ch regular is that he had his own personal meme (バリバリ順光でサクッとバリサク), which got him the nickname, but said nickname was re-used when some Sound Euphonium character did a sax solo, which "stole" the nickname from him. Then KyoAni did some advertisements where "his" trains were covered in stickers, and he snapped because they "defiled" his train waifu.
