Shinji & Ero

Shinji & Ero weren't "normal" people, as anyone could clearly seen.  They had been in separate bodies once, two completely different people who happened to meet due to fate.  And when the shark & dragon fell in love, they took part in an ancient ritual of Shinji's family, which made their two bodies into one.  And so, they lived as one, two husbands bonded together.

Both are He/Him.
