The Last Valkyrie: I Am Poseidon

The introduction is too weak, please read the text. I traveled through time and became Poseidon in the Last Valkyrie. I was so angry when I thought about my ending. I, the mighty Poseidon Archmage, actually went to a draw with a warrior. Now that I have become you, I will help you avenge your hatred. I actually have the skills of Kisame from Naruto. Let's see how I can change my destiny and become the strongest god. This novel and its characters are purely fictitious. Any similarity is purely coincidental and should not be imitated.
