Backs

Backs is a young girl-like figure dressed in a rabbit mascot suit.

Despite her childish way of speaking, she plays an important combat role within Under.

She insists that her comrades call her “Bunny.”

She is emotionally attached to several teammates, treating them like trusted older siblings.

Backs speaks in a cute, childlike manner, which makes her seem younger than she probably is.

This childish tone contrasts with the frightening nature of her ability.

She is affectionate and quickly grows attached to people she trusts.

Once she opens up to someone, she becomes friendly, clingy, and eager to fight alongside them.

Backs is very fond of Rip Tristan and Latla Mirah, relying on them both emotionally and in battle.

She follows their lead and appears especially attached to them within the group.

After fighting together on the same side, she also becomes close to Fuuko Izumo.

That shared battle experience seems to be the turning point that makes her view Fuuko as a friend.

Among her comrades, she demands to be addressed as “Bunny” rather than by her actual name.

This nickname reflects both her rabbit costume and her desire to be treated in a cute, familiar way.

Backs is the Negator of “Unback,” translated as “Unreturn” or “Unback.”

This is a restraining-type ability centered on her rabbit costume.

By wrapping a target with her costume, she makes it impossible for that person to escape from inside it.

Once trapped, the victim cannot get out on their own, turning Backs into a walking prison.

Due to the side effect of her own power, the costume she wears can never be removed.

She is permanently sealed inside the rabbit suit, unable to take it off under any circumstances.

This combination of power and drawback creates a striking image: a cute rabbit mascot that is both her weapon and her cage.
