Titan of Light (OC Ultraman x Attack On Titan)

This is what-if Akira sends to another world other than Dxd universes.

Akira landed in A world where Giant humans ate small humans until he found Ultraman and used his power to protect humankind from Titan and Kaiju.

Disclaimer: I do not own Attack on Titan or Ultraman, but I do own my Original Character.
