Description
Sold to the demon Sullivan by neglectful, exploitative parents, Iruma Suzuki endured dangerous labor and lacked formal education. This harsh childhood forged exceptional survival instincts, most notably an "Overwhelming Crisis Evasion Capability" allowing him to dodge virtually any attack, though he possesses no offensive abilities. Sullivan adopts him as a grandson and enrolls him at Babyls Demon School, warning Iruma to conceal his human identity to avoid being eaten.

Iruma has cerulean hair featuring a distinctive ahoge (cowlick), large blue eyes, and stands approximately 5'2"–5'5". He wears Babyls' standard male uniform: a blue jacket with white accents, matching pants, a red bow with a demon-eye decoration, and dark dress shoes. Key accessories are the gold Ring of Gluttony on his right middle finger—absorbing and storing magic—and a feather earring gifted by his mentor Barbatos Bachiko upon achieving Rank Hé (5). During his "Wicked Phase," induced by the ring's spirit Alikred, his appearance shifts: hair darkens with purple highlights, eyes narrow with slit pupils, and clothing becomes disheveled. Post-Music Festival arc, he wears dark nail polish.

Extreme selflessness and pacifism define his personality, stemming from childhood trauma. He struggles to refuse requests, especially pleas for help, and avoids confrontation. Initially timid and fearful of discovery, he gradually gains confidence through friendships and achievements. He remains oblivious to romantic attention due to unfamiliarity with affection. Despite his kindness, he exhibits resilience, rebounding from setbacks pragmatically. His Wicked Phase amplifies assertiveness and charisma, making him manipulative yet strategically effective; he leverages classmates' abilities to secure resources or aid others, reverting afterward.

Academically and socially, Iruma begins at Rank Aleph (1), the lowest demon rank, after the ranking owl deems him "immeasurable" and grants the Ring of Gluttony. He accidentally summons teacher Kalego Naberius as his familiar. He befriends top student Alice Asmodeus after dodging his attacks in a duel, earning Alice's loyalty, and bonds with Clara Valac. His empathy and leadership unite the Misfit Class, elevating their ranks. He joins the Student Council under Ameri Azazel, who helps him cultivate ambitions like rising in rank to protect others. By the Walter Park incident, he resolves to become stronger, reaching Rank 5.5 (between Hé and Vau) as of recent arcs—the second-highest student rank at Babyls.

Notable abilities include archery training under Bachiko, complementing his evasion skills with precise long-range combat. The Ring of Gluttony absorbs and converts ambient or enemy magic for his use, though its spirit Alikred initially causes personality shifts. He employs this ring to avert disasters. His tactical acumen shines during his Wicked Phase, orchestrating complex schemes.

His development centers on overcoming isolation. Initially fearing exposure as human would cost him friendships, he later accepts secrecy preserves these bonds. He evolves from seeking survival to aspiring to become the Demon King, fueled by his unifying influence and feats. He learns to rely on others and embraces his demon world life while retaining core human values like compassion and nonviolence.
