Scryed is the most likely one so far, the song fits Kazuma, the only problem is it's got a subrefernce to being about a love and the only person who can fit for Kazuma's "love" is a guy (bestfriend type) or an 8 year old girl... He doesn't really have a female love interest in that way.
Besides Scryed, Gundam Wing or Gundam X would also work for it, but... Don't want to use Gundam.
I want to make an AMV to Hunter x Hunter and another Hikago video too.
This will have to wait until I get settled into my sister's room.
