It's been a bit since I played those 2 routes, but knowing what we know of her from Retsnom and KG, I suspect that she already new she and Gaku fucked up and that Yugamu was dead and dangerous, so she sacrificed herself so the rest had a chance to runaway

She just put on the front of being a crazy dumbass in front of everyone

It's really sad that Takemaru just keeps on calling her psycho bitch both before and after her death, not even given her some ounce of respect or decency
