No, fuck that old bat, let her live like that, Yuuko forgiven her but she did shit to be a better person and continued to be a grumpy old twat.
Now Yukariko remember her love to her? Didn't she see through her being spared instead instantly killed?
Fuck that.
Also, poor Teiichi broken heart, it's gonna be hard to move on, maybe Kirie should stop being such a tsundare and confess...
Thanks for scanlation!
