A Certain Scientific Railgun?

I vote for A Certain Predatory Siscon!

Kuroko outshone Misaka as a character. Though techinically she "compliments" the protagonist Misaka, you can just as easily say Misaka provides a target for all of Kuroko's fantasies.

Her powers are amazing too. Even if she doesn't reach Level 5 with ultimate precision and range, all she has to do is master some dart-throwing techniques and increase her teleportation speed. Imagine her rapidly teleport around the battlefield letting off projectiles while simultaneously dropping some from above. You'd have your hands full dodging them already, let alone looking out for her sweeping kicks from below.

Her only problem is the lack of lethality in her attacks, which explains why she has to pin them down first.

The hair colour was off, but otherwise it could have been her.

PS: The OP is pretty catchy. I was afraid they'd use another Kawada Mami song. Index's OPs by her weren't good at all.
