DxD: God of the Sea [Paused]

Imagine a man being reincarnated with the looks and powers of Poseidon from Shūmatsu no Valkyrie (Record of Ragnarok) in the world of DxD. The story is set years before canon timeline, this is the story about a fearsome God that slay's his own kind for overstepping their bounds and getting in the way. I do not own the cover, Highschool DxD or Record of Ragnarok.
