I [i]believe[/i] [@dblade26]’s Ken Kazetani and [@DangDude]’s Chihiro Kazehana are very similar (they both have ‘kaze’ in their name!) due to both of their quirks serving as being wind-oriented even if the mechanics may be different.

I agree, but I think a rivalry like Eijiro and Tetsutetsu in the anime can make things even more interesting.  Though if you're not really looking for something like that, would you allow them to change their character's quirks to something else?
