Thats what I tought, Kurama's power is between the Dragon Kings and the Two Heavenly Dragons (Ddraig and Albion),

Yes, there are only a few individuals in DxD who can compete with Kaguya (Ophis/Great Red/Trihexa are superior by far to her though). But when you know that there are Otsutsuki stronger than Kaguya, the world of DxD is relatively weak compared to them, if the god of Otsutsuki decided to come himself in his true form for example, even Great Red or Ophis wouldn't be able to do anything. Also, Sasuke still doesn't know about the existence of characters like Ophis or others so he's only going by what he's seen for now.

Sasuke entered there to cover his identity, this is true but only for normal students (He manipulated memories to enter there so it doesn't really matter) the devils there know as well that he isn't normal either so yeah

Of course no, she's going to be important in the story, one of the major changes is that she won't be with Masaomi Yaegaki.

Yes, except that it takes time, he can't change in just a few days so he will be a little more "nice" than after a certain time

Thanks! It's not entirely ark centric and there are only a few elements of the game but I plan on using the game's lore at some point

Erza is the main but ngl I don't know who else will be in it I will probably do a vote later, thanks

I will not use the knockout method because thats the game's way it would be weird to succes to tame a dino just by sleeping it in "real" life

The system is not totally the same its inspired so no engrams but inventory later yes

Yes, he will have similar magic to Take Over since most dinosaurs are weak (only their traits will be interesting to him)
