Replica

Replica (レプリカ) is Yūma Kuga's guardian and one of the five main characters of World Trigger. It is a self-described "multi-task Trion Warrior".

Appearance
Replica resembles a rabbit head, and is black in color. It has two white slits for eyes and a thin purple line of light across his body resembling a mouth. It 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, it does not interfere in Yuma's direct decisions as it believes Yuma's choices are his own. It also assists him in battles, like when it prepares certain sealsfor Yūma.

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

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