Ranbyou

"Go die!"

Ranbyou (蘭豹) is a 19 year old female Butei Masters, who is an instructor at Tokyo Butei High School Assault division. She is an Assault departments instructor that looked like a Hong Kong mafia leader. Students call her the "Human Bunker Buster". Her catchphrases are "Go die!" or "Death!". She is best friends with Umeko Tsuzuri and interacts with Yutori Takamagahara.

Personality
Ranbyou tends to be wild and unpredictable, especially when she is drunk. Also, she is renowned for her ability to read people, whether they be Butei or offenders and has animal-like senses when it comes to that. An example would be seeing through Riko's disguise when she pretended to be a female officer to stop the fight between Aria and Kana. In addition, she tries to go on blind dates with hopes of meeting a man who likes her, however they always go wrong and always rages at her class when they do go wrong.

Ranbyou's hobbies are drinking, reading trashy magazines and gambling. Her apartment is a mess, with the floor covered in empty beer cans, gossip magazines, empty bento boxes and dirty laundry.

Whilst she is violent and has a bad temperament, it's been hinted at that Ranbyou cares for her students deep down. While Aria was battle Kana in Assault, she said she would have stepped in if Kana had displayed actual killing intent. She also tried to protect Kinji and Reki when they angered the headmaster. When Kinji became burdened with debt after being expelled from Butei high, she introduced a teaching job to him and treated him to some microwaved frozen food.

Appearance
Ranbyou is a 19 year old young woman with long brown hair tied in a pony tail and wears a green tank top. However, she does wear a business suit when going to Headmaster Takeru Midorimatsu as shown in the epilogue of Volume 11.

Background
Ranbyou is so renowned in Hong Kong that her very name strikes fear into criminal's hearts. She may have become a teacher, but because of excessive and continued violence, she's been discharged from several Butei High's, and so she keeps moving around.

Trivia

 * According to Kinji, some male students at Butei high would purposely get in trouble so that they could receive punishment from Ranbyou or Tsuzuri, apparently enjoying being abused by beautiful older women, Kinji thinks they have some screws loose in their head.
