[Fanfiction] Ragnarok, Eclipse-light Fantasy

Base story idea-plus description

Norse, or maybe Irish? Native American? Based thing. Sorta same premise as normal MC.

Our boy(soon to be shapeshifter maybe? Idk yet) is originally from a different world(not the one he gets transported to...) he happens to be on the perfectly opposite side of the world from where Og oc is, and due to the laziness/idiocy of the goddess rushing Tsukoyomi, a mishap occurs, causing Alyx to get dragged into the same place as MC(Makoto? God I'm too tired for this) Due to the SHARP difference in both suppression of mana, but also Aura(in his parents birth world, sword Aura exists in addition to mana) he passed out while teleporting, she sends Makoto(gonna use that since I think that's the oc MC name) as normal, but due to his unconscious and non-moving state, the goddess almost misses the fact that he's there, and so, last minute decides to drop him at the farthest corner of the ocean.(Does not say this out loud, he has never seen her, and neither hold a grudge)

as his body adjusts slowly, the god of whatever ethnicity/culture/homeland I choose, as of right now it's either gonna be Fenrir/Fenrys, or a wendigo... Or idk from Irish, I'm the least informed on their culture/gods/myths either way... Will come down, and in his unconscious state, grant him instincts and a lot of their authority, (Way less than what Makoto gets, as Tsukoyomi I think gave basically everything to Makoto, and I'm assuming he wouldn't notice Alyx due to the timing of his drop being after he speaks to Makoto.) However his body seemingly under more pressure then what makoto's was, adapts a little too well to the power the god/myth gave him.

The normal instinct to go up for air Is overwrote when his body finds itself swimming down, towards a small cave, which holds an air pocket, and an Mythical Monster(the thing which gives him his demi-plane and his first contracted creature ... Still don't know what I want it to be, not a dragon, something sea related... Maybe kraken, or Scylla maybe the actual physical unknown form of the whirlpool chrybdis? Any way. He ends up beating it with his adapted body and unconscious gifted instincts, kraken forms the contract before being fully killed, and it ends up being a 85-15, in Alyx's favor... 3:23am rn, don't wanna think more, but I hope someone else thinks this is a good idea... I need to charge my phone now, and sleep... Good night, don't let the nightmares bite...
