I see. Looks like this chance is pretty small, as I was once following hungry Bella student for, like, 2 minutes or so and never once she tried eating me or other students. Funny thing is that before this, I got very close to her and she sneakily devoured me. But I managed to escape.
Also, I remember long time ago someone saying somewhere that Bella can eat Ligeska. This is partially true, because you can eat student Ligeska as student Bella, but I never managed to make Apex Bella eat Apex Ligeska. So I can only guess that's not possible.
Btw, i noticed that you're pretty active in comment section, answering people their questions instead of the dev(they're pretty inactive here, only rarely answering someone) and you've been doing that for a long time now. Good job!
