Replica/Relationships

Yūma Kuga
Replica is Yūma's guardian, so it is very protective of him. It also frequently gives Yūma advice and helps him in battles.

Osamu Mikumo
Like Yūma, Replica trusts Osamu. It serves as a link between the two of them, and like it does with Yūma, it frequently gives Osamu advice and sometimes helps him in battles.

Yūichi Jin
Jin respected Replica, calling him Professer, a title reserved for teachers, out of consideration for the vast amounts of knowledge Replica brought with him. Jin blames himself for Replica's abduction during Aftokrator's Invasion, and has promised to make it up to Osamu and the rest of Tamakoma Second.
