The dragon that appears in the second ending of season two is kirishima Kirishima appears to be a half dragon and is said to have lost a one-on-one duel against Katsuki, making him his servant and loyal companion now.

There is a theory that this pact is the reason why they have similar tattoos on their right shoulders and as the K can mean kirishima or that the K is katsuki and you can see that it is a dragon that surrounds it. (sorry foor my bad inglish)
