MangaEditAfter Tsukune and the others defeated Raika and continued on their way to save Moka they entered a room with multiple doors; as a method of choosing a path Fang Fang Huang threw some coins to the floor to see which one is safer. As the others continued on the path that Fang Fang predicted it was the safer (although it was full of deadly traps), he stayed behind, knowing that someone was following them and to Fang Fang's surprise that it was a girl: Routier. She attacked Fang Fang, but as he knew she was there as the fortune said there was terrible luck behind them he evaded the attack and said he was the next leader of the Huang Family and that he would be her opponent. She was relieved and happy that he would be her opponent stating that she loves teasing weak people and that he looked the weakest of all. She then created a sound barrier that won´t let any sound to be heard and pulled out a chainsaw and revealed herself to be Fairy Tale's 4th Subdivision leader, she then proceeded to attack Fang Fang, and then asked if she could make him hurt more while blushing which could mean that she could be a sadist. Then she insulted Fang Fang by saying he had the eyes of loser and afterwards she licked him and said she couldn´t believe that he was the boss of her rival family, revealing that she is a member of the Miao Family and then cut into his shoulder with excitement, to the point of screaming of pleasure while cutting him. Luckily, Yukari Sendo stopped her from killing Fang Fang by sending a barrage of tarot cards to knock her off-balance. Routier became enraged, growing two horns from her head, although her true Yokai form remained unrevealed. She charged with her chainsaw towards Yukari but was blocked by Fang Fang's coin sword, who then inflicted a powerful elbow blow named "Senzan Touchuu"(Mountain Piercing Elbow Blow) that sent her flying back, unconscious. She later appeared in the arms of the leader of the Miao Family, Xia-Long Miao, and watched him fight against Fang Fang with sadistic pleasure.
She later appeared with Xia-Long Miao and helped Tsukune and the others fighting Alucard. She used her chainsaw to cut the Alucard's tentacles but realized it kept growing and regenerated, but this actually made her happy and blushed. When Tsukune asked who she is, Fang Fang said that she's "just some crazy sadist".
Routier is a young looking girl, whose height is similar to Fang Fang's, with short hair with a ribbon on each side of it. She´s seen wearing a sailor fuku like dotted dress.
At first she seems to have a serious attitude towards her opponents, but then she shows a sadistic attitude as shown when she was cutting into Fang Fang with her chainsaw blushing while doing it and even screaming in pleasure, so she is the contrary of Ruby, a sadist.
- Knives: Routier was first seen using two knives during her fight with Fang-Fang before switching to her chainsaw.
- Youjutsu: Routier also used the knives to cast a youjutsu barrier that blocks off sounds within the hallway
- Chainsaw: After using her knives to cast the soundless barrier, Routier switched over to a chainsaw with it being her favored weapon as she drowns herself in the pleasure of hearing her victims' screams.
Powers and AbilitiesEdit
Oni Physiology: Like the other Fairy Tale Subdivision Deputy Leaders, Routier is an individual possessed of tremendous strength, speed, and power, which was potent enough that Fang-Fang noted that she was as powerful as Kokoa Shuzen, the youngest Vampire in the Shuzen family. When she becomes angry, Routier's horns grow and she releases a more potent aura.
- Enhanced Speed: When confronting Fang-Fang after most of the others left the hallway, Routier immediately went to attack him with some of her blade attacks managing to wound him without him even noticing the infliction. Her speed allowed her to temporarily overwhelm Fang-Fang before Yukari stepped in where when angered Routier had immediately attempted an attack on Yukari before the witch was capable of reacting.
- Enhanced Strength: During her fight with Fang-Fang, Routier was able to pin him down on the floor with her chainsaw and Yasha being unable to pry her off at that time.
- High Demonic Aura: At the beginning of the confrontation, Fang-Fang noted that the potency of her aura was as strong as Kokoa Shuzen. Later when Yukari interrupted the fight Routier unleashed a very high amount of Yoki that scared the witch.
- Expert Weapons Specialist: In addition to her natural abilities, she is a very skilled practitioner of bladed weapons, such as knives and even a chainsaw, which she used in her initial assault against Fang-Fang. Despite these traits, however, she was ultimately no match for her opponent, who exploited her moment of inadequate awareness when she attempted to attack Yukari Sendou; Fang-Fang incapacitated and bested her with a full-power application of a signature technique.
- Youjutsu Practitioner: At the beginning of the fight, Routier used the knives she first attack Fang-Fang with to create a sound barrier within the hallway so that nobody can hear his screams when she fought him using her chainsaw.
- In the Omake for Volume 11, it is shown that Routier is deeply in love with Sai-Lung.
- On that note, she also fantasizes about sadistic pleasures with Sai-Lung, once imagining him as Wolverine from the X-men where she could cut him, have him heal himself, and cut him again continuously.
- Her chainsaw is similar to Juliet Starling's chainsaw from Lollipop Chainsaw a zombie hunting video games
