Ryuen

Biodata

History

Ryuen initially rules Class C through intimidation and pursues victory over the other classes. During the Uninhabited Island Special Exam, he works with Ibuki Mio to take Horikita Suzune’s key card, but Kazehara Tetsu intercepts and defeats him. Ryuen subsequently seeks Kazehara out to learn how Class A solved another exam’s hidden pattern so quickly 96 97 98 118 141.

At the Sports Festival, Ryuen obtains Class D’s event list from Kushida Kikyo and pressures Horikita over an injury incident, demanding that she kneel and pay one million Personal Points. Horikita exposes the scheme with a recording. Kazehara then negotiates an IOU with Ryuen in exchange for information about a traitor within his class 149 165 175 176.

A later defeat by Kazehara leads Ryuen to consider dropping out. He stays after Kazehara threatens consequences for Ishizaki Daichi and Albert if he leaves. Ryuen publicly withdraws from leadership, though Kazehara later identifies his continued influence over Class D. Ryuen eventually returns to the forefront as its Commander Tower, accepting an exam position that would mean immediate expulsion if he lost 207 208 318 319 332.

Ryuen later transfers to Class A after losing a match in which he says he had bet everything. Kazehara puts him in charge of the class’s cultural festival preparations, with Katsuragi Kouhei assisting 492 494.

Appearance

Ryuen is tall and lean, with long dark-red hair that can fall across his left eye. His open collar and hands-in-pockets posture contribute to his defiant appearance 118 317 448.

Personality

Ryuen is confrontational, mocking, and willing to use intimidation or betrayal to win. He rejects cooperation when he believes it limits him, but his pursuit of Class A is more sustained than his professed desire for stimulation alone suggests 141 149 195. Defeat does not reliably end his challenges: he approaches Kazehara again after being beaten and later fights him on the island despite knowing the risk 205 206 448 449.
