so

Specifically, I don't know. Some say he's the gluttony ring but there might be a bigger secret

He comes out of the ring, the gimmick is the higher Iruma's rank is the more developed Ali-san gets

He's originally the ring that he received in the valley of death, where the whole misfit class raced and Iruma coming in with a big ass bird. Like Chichi said, it is the ring of Gluttony that has a prophecy in it. Like whoever owns it will rise and take the position of demon king.

When Alikred or also known as Ali-san was introduced, he was a hungry demon and only calmed down when Sullivan or Iruma's grampa fed it and like adjusted it so Iruma can use it. Not only that but Ali-san was also responsible for making evil Iruma kun.

I have theories that Ali san was like a part of the old demon king or IS the demon king. Anyways that's all and Im sorry for the info dump ┗( T﹏T )┛

Alikred = derkila, not confirmed but they also have the same voice actor in the anime

So that was the reason he's hiding from Sullivan. I've also wondered if that also explains that survival trial after he showed his true self which caused him to slumber.

Lmaoo is that true? Cause in bleach ichigo's zanpakuto's spirit zangetsu and Yhwach have same va and looks similar and they ended up being related.
