[Kentaro Yabuki(矢吹健太朗)?Hasemi Saki(長谷見沙貴)] To LOVE-Ru - Trouble - (To LOVEる -とらぶる-) - Trouble 76 (トラブル76 「お泊り会」)[Shonen Jump(ジャンプ)][2007-50]

It seems one of the girls can control and also reshape his hair, probabily she appears in earlier volumes, but for now I only have the recent chapters. The manga is written by Hasemi Saki, and illustrated by Kentaro Yabuki (creator of Black Cat). The chapter's title is Ohakuri Kai.

I'll leave the preview pics until I get the rest of the current manga, so I can make a compilation with the relevant chapters.

EDIT: She appears first in Trouble 42 ?, then battles again in 72, and seems to have the ability to reshape her own body as well.
