Goin for VIOLENCE TIER 3 with possible bonus tier for Ginko; he will likely try to resist/possibly confiscate her weapons if he can but he's really unlikely to. Actually fight back, unless Sachiko manages to trigger Troll Rage somehow

Aaand HALLUCINATION TIER A he's from a psychological horror canon he can deal with it

edits to add the exception that i'd like to... plot/discuss before seeing people he knows dead comes into it, i don't want to count it out entirely but that would mess with him way more than most stuff
