Ignoring Ooki for a moment, that little yandere shit should really find something else to do with her life.
Now about Ooki, this girl is scaring me even more... didn't think possible, but she is, the worst about her is that i am no closer to understand her actions. Does she get off with this situation in any way? I simply can't think of a reason besides that she is a manipulative sociopath that likes to see people grovel at her feet, but even then it doesn't explain everything, she has gone to many times out of her way to be in places and do things that don't add up... the only other thing is that she may be the most "long con" wingwoman in the face of earth.
..................... that last punch was completely unnecessary.
The only good thing i saw in this chapter, Yankee Oppai-chan isnt sing the sarashi anymore.
