Kyouko Rikugen

A hero and sage of the Holy Spirit tribe, one of the Four Heroes. Most of his body is made of slime-like structures, so he can transform into other forms, not just human. There are no detailed records from his original world, but in other worlds, he possesses intelligence that allows him to converse with people. He assumes that Lasie is the mastermind behind the plot and forms an alliance with the anti-human forces to fight against it. It is said that he developed his own intelligence in order to understand the attempt, and the evidence is that he can speak human language.
