I am still having fun with the gag, but the evil boobs being so evil got me a little down, i could deal with Giri's actions but this detail sounds so strange to me and now she threatened another girl and the story is taking it seriously it is so strange.
Ooki is too powerful, she actually replaced a big boobed yankee character with a flat(ter) yankee, so she successfully removed Okada's opportunity to look at other boobs than hers, which equates to him not looking at any big boobs at all thanks to Katagiri.
Why is she putting so much work for a creep like Okada anyway?
Poor Katagiri.
