Errmm... I disagree... ^^;; However, with no material to back up from claim, I'll just have to disagree on general basis.
Also, I'm fairly sure the Caster has no divine blood. I'd have to look up her legend more closely to be sure tho'. The ears are just there for that elf-ish appeal.
Also, odd hair colors in general aren't unnatural; Shinji has BLUE hair for goodness' sake! Sakura has purple as well, but that has a reason behind it.
I found a translated version. Right
here.
Yes, there's actually a great number of those, a lot of them have been translated as well. Unfortunately, I'm unsure as to where they are, I found a lot of them on 4chan but forgot to save them. ;_;
Also, Ecchi, post more! ^_^ I miss your witty comments.
