You remember that elf he was talking about? She healed him. On the Novel, you actually see him...doing the fucking fighting, instead of cutscreens, and he takes out all the leaders making everyone retreat. I'm saddened he went with the ol' 'SHALL NOT KILL' BS, but anyway awesome as fuck.
Problem is that the anime seemed to have forgotten that they had a plot to run and, I dare say, wasted alot of episodes.
And tsundere ending, lol everything is back to normal. Oh Jesus, it's cute sometimes, but they could have not chosen a worse time to cop out.
Aslso the anime doesn't dwell on Louise's depression, and if I'm not mistaken, she tries to kill herself or something. (I'm kinda glad they did...)
