Well, I actually named many a pet after anime characters, without the nomen-est-omen thing though. Just cuz I liked the name.
My pink cat Souzou was named after Souzou from RK.
My other cat Katzu once stole a koi from the neighbours and as he miraculously survived (stood above god), I named him Kamui. Katzu caught him a second time though...
My lovely dog is named Touya like the one in AnC, but I sorta regret that: it sounds too cool, I shoulda chosen a cute or funny name like Titus, Ippolito or Teeco. His kennel name was Kumo.

If I ever get a female dog (either a breeding bitch for Touya or a Saluki), I'll call her Kirara :)
I also had countless rats, hamsters and mice (like Chichiri) named after anime characters.
My mother sometimes calls me Fushigi for being a weirdo.
I usually don't name people after anime charas, but I do pronounce their names in Japanese or attach suffixes, just for the fun of it: Yo-chan (Jonas), Ge-kun (Gert), Bimu (Wim), Sorenji (Solange),... I love the Sorenji one.
As for my own name, I'm Anna Miryam. Anna the gifted, and Miryam, the crybaby. Both true^^; I was born in Tel Aviv, so guess it actually refers to "Anna Maria" or some other holiness.
