Hello!

I don’t know his canon either, but looking at his Wiki page, I think his vitality would be the biggest barrier. Maybe if I could get a better rundown of his abilities? I can’t find his info on Wikipedia itself (not the Rakuen Wiki).

Assuming Adam is a normal human being, I believe Duzell should be able to defeat him. You mentioned he is capable of fighting. Is he a strong warrior?

Duzell just got new weapons, and I need to see what abilities they have.
