I feel like the lack of any extra information on Juhino's emotional state signals that it's not relevant and we probably can't pin anything on her, so I guess, yeah, that's not an acceptable answer at this point.

idk, should we poke mods about the handwriting samples? I think that's the only thing that wasn't covered by this update. Obviously Ildsina may have refused to provide handwriting, and Kellban's is irrelevant, but it might be good to also get samples from Crisul too now that we have him to deal with.

I'm personally leaning toward Ildsina because Crisul seems too obvious, but objectively speaking, both have equal points for and against them. Ildsina won't talk on the stationery, but outside information says the rivalry wasn't hostile; Crisul won't talk on where he got the money, but has a reputation for being a nice dude, aside from the gambling. The stationery points toward Ildsina, but the handwriting points toward Crisul.

Which...really makes it hard to pick one or the other as the primary suspect, and that's why it seems to me like they both might have been involved. If we had any more evidence to implicate one or the other, I feel like the choice would be more obvious.
