Yeah... how Amatsu flies... I seriously have no idea. The game at least explains how the heat and gases inside Yama Tsukami's body allow it to levitate, much like an hot-air balloon, but we've got nothing about Amatsu.

I honestly can't think of anything, not even with imagination, how that thing manages to fly. Magic can't be it. One definite answer however could be "video game physics lulz". -_-
