UMP9, often shortened "9", has a preset candid and friendly personality and is a capable T-Doll. After her encounter with SMG UMP45, she has developed a strong admiration for her, and while knowing she can't match SMG UMP40's importance in 45's eyes, she aims to be useful to her in any way possible and to help her accomplish her goal. 9 often assists 45 in electronic warfare, but their hardware differences make her abilities a far cry from 45's. During the formation of Squad 404, she also warned AR HK416 that should she try to kill 45, she would have to get through her first.

Within Squad 404, 9 acts as 45's lieutenant and usually sides with her in any situation, though she is not free from falling on 45's bad side occasionally. Despite how dysfunctional Squad 404 is as a team, 9 insists on calling it a family. Unlike 45 and 416, 9 cares about the squad's reputation and bears no hostility towards AR Team. She is also in charge of erasing all memories of 404 from the Neural Clouds of Dolls they made contact with during operations to preserve their team's secrecy. 9 has above-Doll-average knowledge of world history as noted by Angelia. - IOP Wiki
