YES THAT'S IT... Okita had named him 'Smegma', so I think the text box says 'Smegma has died!'. What an inglorious run.

Actually if Mona is into cute stuff perhaps we can use one of those dollmakers (like the ones on https://picrew.me or, more classically, https://www.dolldivine.com) and they can each "create a character" for a game? It might be especially fun because they're both usually fully dedicated to their work and super serious about it!

I put my post up here, if you want to tag in (no rush though!) - the answer to the riddle is the echo, according to the riddle site I took if from!
