Man in Diga: Turn into Opu at the beginning

Due to an accident, Xiao Tian came to the world of Ultraman Diga and was bound to a super cheat called the Ultraman System.

Diga: Xiao Tian is my most respected senior.

Hong Kai: " We’re both opals, but why is Xiao Tian’s opal stronger than mine? And there are more forms."

Gagula: One Red Kai is already giving me a headache, let’s have another Opu

Villains: Not good, Xiao Tian is here, retreat quickly!
