Kaitou St. Tail Couples

Yusuke and Keiko were the best of friends since childhood despite one being a boy and the other a girl. They go to the same school and are in the same section. Clearly, Yusuke's got Harry's messy black hair going though he has brown eyes instead of green, he doesn't wear glasses nor does he have a scar. However, Yusuke has a certain disregard for school rules and is very very brave even in life and death situations (like Harry).

Keiko is almost exactly like Hermione in many ways. She has both the brown hair and brown eyes (though her hair is shorter). She is very good in academics, follows school rules, a team leader, and a very brave girl at that. She worries about her friends a lot most especially Yusuke (like Hermione worries a lot about Harry).

There isn't much of a rivalry in Yu Yu Hakusho when it comes to love, but for the first few episodes, there was a bit of it. See the trio in the pic? Looks quite familiar, eh? That tall guy is Kuwabara. He has some similarities to Ron: tall, has red-hair, disregards the school rules and is sort of the guy people are joking on. Kuwabara is also Yusuke's best friend (like Ron and Harry).

Kuwabara was once very attracted to Keiko but only for a few episodes. Next, he was attracted to Botan but also, for a shortwhile until he settled for Yukina. That's kinda like Ron attracted to Hermione, then to Fleur and then....I dunno who's next (but I'm hoping it's Luna. Don't kill me! *_*)

Here's another Harry/Hermione look-a-like from Yu Yu Hakusho though the connection between them isn't quite certain. Koenma and Kuwabara's sister, (I forgot the Japanese name) Suzie (as what she is known in the Philippines). The connection between these two is quite short, but I think they make a cute couple. Koenma ends up saving Suzie in around 2 episodes but it was really a sweet save to me.
Though Koenma NEEDS to lose that pacifier, he has the messy hair (though it's brown) and has a mark on his forehead where Harry's scar is. He's brave when he needs to be and has a genuine concern for his friends. Suzie's got all the looks of Hermione going there: brown hair and brown eyes. She's also brave and I believe, intelligent.
