first off thank you for the chapter...........um... so not only did it illustrate that Nine was conflicted during the second part of the fight with Migen in an attempt to save some face, Migen was having to much fun at the moment outdoing and showing off his superiority to Melissa with just his speed, agility, and brute force to pay attention to the other three in the room, but he gets an ass pull power up after Melissa essentially neutered his twin and debuffed him so the powered up Nine could flex/show off while manhandling him and showcasing the lengths he would go for his love..... That's disappointing and feels like an attempt to make up for him standing around last chapter and "man him up" for some grief/guilt induced drama later. I honestly hope Migen survives this he was a fun villain in contrast to the male leads... and while I can see him dying for the sake of Nine angst I have a feeling something will interfere here it will either be memories or Melissa will wake up enough to stop him or something else will intervene... also since he's at the moment cut off from his power wouldn't that make it so he can no longer sustain the field keeping Yuri trapped and it should be dropping shortly regardless?
Anyway the explanation regarding what Nine did to get kicked out was a nice touch, and really fit Nine's personality.
