Yuzuki Katagiri (片桐弓月, かたぎり ゆずき, Katagiri Yuzuki) is a Model Spider Initiator, younger sister of Tamaki Katagiri, who is also her Promoter. She is a member of the Katagiri Civil Security Corporation.

Appearance
Yuzuki Katagiri is a 10-year-old girl, with messy, dirty blond hair pulled into high pigtails, with bangs, split in the middle and has brown eyes. She also wears a choker and a leather-made vest.

Personality
Yuzuki shares the same attitude as her brother, being a hotheaded and brash individual. She has a tendency to call Rentaro a pervert in any given situation, but reasons for this are unknown. She is shown to be overconfident in her abilities, such as seen with Tina Sprout, believing she could easily defeat her, but the latter beat her without any difficulty. Aside from this, she later puts out that she is weak and would be a bother if she was part of their team, but after Tina reassures her and told her that she was amazed at her skills in keeping a former rank 98 on the defence, Yuzuki jumps in joy, showing her side of affection. She considers Tina to be a really strong and cool person, going as far in saying she loves her, albeit platonic, and to marry her. She shows her playful side when she joins in with Enju to strip Fuse's underwear and dress, to check whether Fuse grows a tail or not.

Third Kanto War arc
When Rentaro brought Tina to Katagiri Civil Security Corporation office, she greeted Rentaro rudely and constantly calls him a pervert.

Rentaro tries to reason with hthem to join the adjuvant. It ends out that a fight between Rentaro and Tina, and the Katagiri brother and sisters, has to be done in order to decide whether the Katagiri brother and sisters are to join the adjuvant or not. After losing the fight, they decided to join the adjuvant.
