Replica

Replica (レプリカ) is Yūma Kuga's guardian. He is a self-described "multi-task Trion Warrior".

Appearance
Replica resembles a rabbit head, and is black in color. He has two white slits for eyes and a thin purple line of light across his body resembling a mouth. He also has two appendices on the top of his body which resemble rabbit ears, and two other, foot-like appendices on the underside of his body, which seem to serve as a landing support, but were never seen in use, as Replica is always floating.

Personality
Being Yuma's guardian, Replica always provides advice for him, telling him what's right and wrong. However, he does not interfere in Yuma's direct decisions as he believes Yuma's choices are his own. He also assists him in battles, like when he prepares certain spellsfor Yūma.
