Words fail to accurately describe how much I dislike Asahi.
Generic "I'll take over the world."-villains, I can take. Tragic backstories, good intentions, sure, why not. But for some reason I cannot accurately express, Asahi makes me hate her on a entirely new level. The way she just waltzes through life without much effort due to her charm magic just ticks me off something fierce. And then she latches on to the one person that is able to tell her "No!" as if said person is an error in her perfect little world that either needs to be "corrected" or chased far far away. It's a testament to Ruri's strength of spirit that she has come this far in life without slaughtering Asahi with a butcher knife in public while laughing like a madwoman. I know I would have done so, long ago.
If Ruri cannot break through to Asahi or if Asahi is truly unwilling to accept that the world she has been living in is a big fat illusion brought about by her charm magic, I'd say that she is better of dead. In that case she'd be too dangerous to let live.
