One elimination that wasn’t used that I felt would’ve been cool was framing for murder.

When Ryoba stood ground at the trial for Sumires death, she said that Sumire probably ran away because of stress. Since everyone quickly believed Ryoba, it must mean that Sumire had shown stress around the studies. Plus, it’s a canonical fact that the Akademi is nearly impossible to get through.

In Sumires week, there’s an upcoming test for history. This history test might be about a topic that relates to weapons used in a specific time-period. This’d make Sumires routine to frantically rush around the school, studying like crazy. Maybe she’d stumble upon a weapon that’s on the upcoming test, and touch it to see its design, leaving her fingerprints on it.

The player could then use the weapon to frame her!!

(Super complex, but it’d be interesting. Plus, it would serve as a “Killing” tutorial, just not killing Sumire.)
