Replica

An autonomous Trion soldier that acts as a guardian for Yuuma Kuga; it was created by Yuuma’s father, Yuugo Kuga. After Yuuma joins Border, it holds the position of "Special Advisor" attached to the Tamakoma Branch.

Unlike other Trion soldiers, which appear purely robotic, he possesses a distinct sense of self and frequently offers advice to Yuuma and Osamu. However, he leaves the final decisions entirely up to them; even when a course of action is dangerous, he will offer a warning but never forbid it.
