Hanaki Guriko hails from Kyushu. Not only is he Suzuran's Number One, he's also stands atop all others in Toarushi. He was a spohomore at Suzuran in Hana Tsukishima's first year and is currently still a Senior. Because of his many absences, Guriko was forced to repeat his Senior year while the rest of his year has already graduated.

As Suzuran's strongest man, Guriko has participated in a number of fights, including matches against Zetton, Kurosawa, Butcher, Hana, Tsukimoto Mitsonobu, Muroto Zenmei, and deceased Armament Head Kawachi Tesshou. Despite the number of fights he's been in, Guriko has no known loss. After being defeated by Guriko,Kurosawa Kazumitsu becomes his right hand man, whom he nicknames "Kurosar".

With a reputation for having immense fighting skill known by all throughout Toarushi, Guriko commands a lot of respect in Suzuran, despite his unwillingness to lead his own faction. Even if Guriko won his rematch with Hana (who was already in his third year), he was still able to convince the other students to accept Hana as their leader and to follow his leadership. Third owner of the Bullshit Buckle, which has been secretly passed down from the strongest of Suzuran since the time of Harumichi Bouya. 

He is normally an easygoing man and is always behaving in a jolly, trickster-like manner. He also rarely takes his fights seriously, often preferring to postpone them in favor of spending more time with his women. However, once a particular opponent angers him in some way (like hitting on his girlfriends or messing with his phone), Guriko turns into the Afro-Demon feared by everyone. When in his Afro-Demon state, Guriko goes into a blind rage and attacks everyone within the vicinity. Akutsu Kinji, who always seems to be around when Guriko is in this state, is often on the receiving end of Guriko's blind attacks.

More than a fighter, Guriko is also a womanizer extraordinaire, known for juggling his nine girlfriends at the same time - a fact which only angers the other Suzuran students. The fact that his girlfriends all know about the other mistresses and are okay with it only solidifies his womanizing prowess. Because of his antics, he is shown a few times to have symptoms of sexually transmitted disease.
