Sounds like his heal has perhaps crossed the line into something OP like time rewind territory? Yuki did a number on Lena, but I hate how this plot point keeps getting dragged out since we don't know what happened to her and whether she learned anything after the fight.
Insincere kiss from a scummy harem-seeking playboy, blech. Fuckboy doesn't have a harem yet because he's only got 2 wenches fawning over him. And that's why he's still scheming to get Yuki. Meanwhile, dickhead slaver A-ranker gets possessed by something that seems malevolent. Then gets into a party with the 3 traitors. This might be amusing.
Dion's shiny new goal is all fine and dandy, but I've still not forgiven his insensitive betrayal of his old friend. When is he gonna meet Yuki? Or more like, where is she, anyway?
