I have no idea why so many people are complaining about the father being an asshole.
1. He is not human. He's millennia old. Their relationship is like minutes old. He doesn't care and that's not surprising? He took her in because he found a letter from his wife asking him to take care of their child...and that's it. (blue and orange morality anyone?)
2. Their relationship is like this because of comedic value. I'm on chapter 20 of the raws currently, don't understand much of what's happening but am highly entertained. This poor man had no idea what headache he was bringing upon himself when he decided to retrieve his daughter. My sympathies lol
Also as a tiny spoiler, I haven't seen her give too much thought to her former family. Eh, maybe it's written and I just can't understand but it doesn't seem like that's the case. So they both have quite skewered (not-human?) personalities.
That being said I expect him to start caring about her if even a little but I'm not sure we'll ever reach doting daddy levels...though that WOULD be quite a show.
Waiting quite eagerly for this to be updated. The raws are awesome and I'm stoked!
