Okay thank goodness it ended there. No further manipulation/brain washing on Aya. That just means the sensei kill is VERY personal and it's either Aya gets to kill him or she dies by the end of the arc. I can see the author throwing away Aya as the next Dojima scenario since she hasn't been utilized or close with the girls at all but she's lowkey my favorite of them all.
Will do ANYTHING for a cup of COFFEE
