Description
Ibushi Arima holds the position of vice president within Binan High School's student council, the Conquest Club. He attends class 3-B and is 18 years old, born on November 10th, placing him under the Scorpio zodiac sign. His blood type is AB, and he stands 184 centimeters tall. Wavy dark green hair and red, slightly droopy eyes lend him a gentle appearance.

Born into an upper-class family, Ibushi's upbringing emphasized social appearances and superficial relationships, leading to emotional detachment. His childhood meeting with Kinshiro Kusatsu and Atsushi Kinugawa changed this, particularly Kinshiro's genuine smile fostering emotional openness and deep loyalty. Ibushi now supports Kinshiro with unwavering dedication, often adopting a butler-like role. He prepares tea, mediates conflicts involving strong personalities like Akoya Gero, and maintains council order. His typically calm and polite demeanor contrasts with occasional sharp remarks, though he primarily acts as a peacemaker.

As a Conquest Club member, Ibushi transforms into the Silver Chevalier, Argent, using the activation call "Conquest!". His battle name originates from the Italian word "argento" (silver). Wielding a rapier in combat, he manipulates silver chains to create barriers. He initially prefers observational support but engages directly when necessary, such as confronting Cerulean in episode 11. His elemental attribute is wind, and his special attack, Ulutima Adamas, involves firing a silver beam from his rapier alongside other Chevaliers.

His hobbies include playing backgammon and gardening, specifically cultivating herbs for tea. He enjoys carbonated rice crackers but dislikes snails and salty licorice (salmiakki). Interactions showcase his loyalty: he uses Akoya Gero's first name and occasionally teases him in manga adaptations. He reacts with surprise when Atsushi Kinugawa uses the nickname "Ibu-chan". Within the otome game, he participates in social scenarios like dates, complicated by Akoya's interference.

Across media, his development traces a transition from detachment to purpose found through loyalty and camaraderie, particularly his steadfast support of Kinshiro and the Conquest Club's activities.
