Shinōji Ryūga holds the position of student council vice president at Ortigia Academy of Magic. He possesses black hair and eyes, sporting an off-blue button-up top with gold trim over a white dress shirt, black pants, brown dress shoes, glasses, and a noble-style shirt that complements his calm demeanor.

Logically-minded and rational, Shinōji methodically analyzes situations to find solutions and plays a key role in unifying the diverse student council. Following Obsidian's betrayal—a staff member who nearly destroyed the academy—he exhibits notable caution and distrust towards other staff, refusing to trust them without proof of reliability. Despite this wariness, he demonstrates unwavering loyalty to the student council and its president, Elena Kimberlight.

Shinōji is recognized as the academy's foremost practitioner of levitation magic, a complex and demanding discipline learned from his private tutor, the reputed great magician Gannet Granatus. While proficient in floating objects against gravity, his mastery does not reach Gannet's legendary scale, such as levitating an entire country.

His relationships reflect pragmatic loyalty. He respects Elena Kimberlight but frequently questions her manipulative tendencies, openly criticizing her while remaining a dedicated subordinate. He supports her decision to protect Alto Goldfield after discovering Alto's contract with the devil Vermeil, citing their shared distrust of staff stemming from Obsidian's betrayal. Shinōji also takes an interest in Alto's potential, approving his recruitment into the student council and later urging cooperation to defend the academy against external threats like the military or Platinum Square Magicians.
