Manga Debut Chapter 112

Fuyuyu Tsurugi (剣 ふゆゆ, Tsurugi Fuyuyu), also known as the Queen of the Divine Butt (聖尻の女王, Hijiriketsu no Joō), is a Keijo player and one of the Five Butts (五尻の1人, Goketsu no Hitori). Additionally, Fuyuyu is the current Prize Queen, as well as the current strongest Keijo player in Japan.


Fuyuyu has heterochromia, her left eye is light gold, while her right eye is navy blue. Fuyuyu has short, aqua blue hair with each side of her bangs grow longer. She wears a hooded coat with a ribbon attached on the front. She wears a striped short skirt. She also wears a hairband adorned with short antennas on each side of the hairband. Additionally, Fuyuyu has a long-sleeved sweater with stripes.


Fuyuyu always worries if a paparazzi finds her. Furthermore, she also always worries about what will they write in the magazine. Additionally, Fuyuyu dislikes being found by crowds, going as far to tell Ikumi Yuzuki to wear a mask in order to conceal their identities. Despite her status, Fuyuyu is proven to be humble. When she is found by her fans, Fuyuyu tells them that they mistook her for someone else. Fuyuyu is also willing to offer her autograph.

Fuyuyu strongly tells her fellow East players not to tarnish the name of East. As such, she will not hesitate to bring down judgment on an East player that causes trouble to others.

Fuyuyu often uses the line "as Japan's top player, I will...", when she is about to punish a player that: sullies the name of the Keijo world or disrupting a race. She is not even hesitate to use this line to her fellow Five Butts members, Ikumi Yuzuki. She shows her respect to the former Prize Queen, Reiko Fujisaki, calling her as a "legend".


At some point in the past, after a race, Shibuya informed Fuyuyu that someone committed suicide and was found in the stadium bathroom. Shibuya further explained that the gambler strongly believed Fuyuyu would win and (presumably) bet everything in his possession for her. However, Fuyuyu lost in that race. After this accident, Fuyuyu decided not to aim other goals but to keep her winning-strike to avoid other incidents, realizing the burden she needed to bear for being the Prize Queen.[1]


Unlimited Panty Arc

Fuyuyu blocking Kukuru.

When Kukuru Kashiwaba was about to finish Nozomi Kaminashi off, Fuyuyu stepped between them and stopped Kukuru. Fuyuyu immediately asked who was the one ordered her to do something that tarnished the name of East. A panicked Kukuru replied that she couldn't answer it. Thus, Fuyuyu decided to punish her. After performing combo attacks, Fuyuyu produced a huge amount of electricity and brought them down onto Kukuru.[2] Seeing Kukuru collapsed on the ground, Fuyuyu stated that she went overboard, panicked about what would the magazine write about her.

Nozomi challenging Fuyuyu.

Sayaka assumed that, just like Kukuru, Fuyuyu also wanted to stop Reiko from spreading the "Unlimited Panty". However, Fuyuyu stated that she was just passing by, searching for the rumored Butt Cream. Fuyuyu then advised Nozomi and Sayaka to ensure about Reiko, who was injured after being hit by rubber bullets. Later, when she was about to eat the Butt Cream, Nozomi and Sayaka approached her. Fuyuyu panicked again if she would be reported in the newspaper. Since Nozomi kept calling her by her full name, crowds began to notice her presence. Thus, Fuyuyu decided to run away. But soon, Nozomi held the golden holy sword that plugged into her butt. Fuyuyu assumed that Nozomi wanted her autograph. However, Nozomi declared that they would definitely beat her, much to the spectators' surprise.[3]
