Oguri is so OP, that in fact she's the last boss of the story, not her arc rivals.

An act making her as much of a "heel" as Creek; an act intended to help. Not that Oguri will think about it in that way...

A great victory but the "taking down the monster angle" isn't really valid tbh considering Oguri isn't in peak condition. Should of focused more on Yaeno's amazing achievement rather than defeating the monster.
Just my two cents.
