I've watched this episode twice (with long distances between them) and both times, I thought the suspect was the girl.

I felt like that guy feels too guilty I got it right

Yeah same she is sus

Yeah she is too sweet to not be guilty

Mamiko Noto's voice is too cute to be the culprit, teehee. On the other hand - her voice's airiness can be pretty chilling - she could make quite the yandere if called on to do so.

Too cute but kinda the weak culprit sometimes

I didn't know the Sound Hashira (Tengen Uzui) would use such a petty cyanide poison instead of his two large Nichirin Blades.

Last time I’m gonna see this opening

i guessed it right, well the suspect's pretty sus eversince the beginning so

The guy was too evil
