Seems like she manages to mind control him, but it doesn't go quite the way she expected and he rapes her? He touches his head with his hand by accident, regains his mind, and feels bad about what he's done, but (from what I gathered? I can't read kanji T.T) she either asks him to keep going or somehow her powers affect him through his dick??? And then judging by the last two pages either they start a relationship or they just keep having sex.
Sorry my knowledge of Japanese is basic and my knowledge of Toaru is like 5 years old at this point...
@ Loirider - thanks for the synopsis of the story. Not a great fan of rape scenarios ("hentai" or otherwise) so really not sure if I will opt to commission a translation - even if in the end it could be considered "Touma x Misaki".
