thank you so much! have a happy new yearr (✷‿✷)

wait are both of these in the same universe??

Yes!! Myst, might, mayhem is the story of the original heavenly demon, who started the cult were reading about now… and even though our boy has nano, and the other story is only in the beginning I’d say the forefather was stronger, martial arts is only one part of his strength.
