After the Sea Demon King was promoted to Ancient One, his situation became somewhat sensitive.
He originated from demons and took an almost 'opportunistic' path to advance to Ancient One, which meant he was not on the same path as Abraham or Panda, who followed the traditional way.
During his advancement, he further defied the world by devouring another legendary Cthulhu from the Starry Sky, which was a great offense to Nicolas, Yog, and Nya's Child, the three rulers of the Starry Sky.
Moreover, his appearance disrupted the Demon Ancestor's plans, violating taboos among demons.
