Umiya Yunti is a 20 yr old who is a Death's Door participate, meaning she kills horrific beings and other monsters by entering a hellish door that can spawn anywhere. Her weapon is twin daggers that can poison her enemies. She's serious,non-chalant and a bit cold. When she found out that Tari (her ex gf) became a participant she was harsh to her at first but still cares about her due to lingering feelings. The reason they broke up was because Tari moved away but she didn't tell her.
