Background

Su Yang began as an unusually capable Devil whose growth greatly outpaced his formal rank. Even while still an Intermediate Devil, he wielded Parashurama's Heavenly Martial Arts and developed internal magic circles to improve the efficiency and simultaneity of his spellcasting 22 35. At Kuoh Academy, he fulfilled Student Council duties ahead of schedule, built an automated system to control avatars, and devoted the reclaimed time to magical research 41.

A near-fatal incident left him unconscious for twenty-seven days. He survived through a combination of Divine Talent, the Origin Human Bloodline, and Phoenix Tears; upon awakening, he recognized that his life form had changed into something stronger than most beings across realms 106. His recovery remained visibly incomplete for a time, marked by episodes of coughing golden blood, yet he rapidly resumed fighting opponents such as Cao Cao and later the Phoenix 108 124.

As his strength expanded, Su Yang accumulated Incarnations, Divine Tools, Sacred Gear abilities, Demonic Power traits, martial disciplines, and magical systems. His eventual sealing of Beast Emperor 666 brought Saint's power into his body and elevated him into the Sub Dragon God tier 239 281. He later used the Hub · Hakoniwa and the Modified Spear of Saint Slaying to erase the DXD universe's cosmic consciousness, reorganize its order, and establish Earth as the core of the resulting universe 340.

Afterward, Su Yang continued traveling through other worlds and timelines. His journeys placed him in settings involving Campiones, school-life worlds, simulations, Little Garden Communities, and the world of Titans; in each, he alternated between living an ordinary student life, teaching and mentoring others, and resolving supernatural crises 488 647 842 955 1115.

Appearance

Su Yang is repeatedly noted for an exceptional appearance and an increasingly captivating aura. The Origin Human Bloodline deepened his natural charm without substantially changing his facial features, making classmates perceive him as more attractive after his recovery 133.

• His blood is golden, a visible sign of his altered constitution 108.
• The Origin Human Bloodline gives him an aura described as naturally harmonious with attributes and rules 383.
• His World Dragon Armor manifests as azure armor decorated with platinum-gold jewels 79.
• Even after reincarnation and body changes, observers consistently identify him by his unusually striking eyes and presence 487 881.

Personality

Su Yang is composed, observant, and exceptionally confident in his own judgment. He habitually analyzes people, combat conditions, systems, and magical structures before acting; this allows him to recognize weaknesses in magic, predict opponents' reactions, and rapidly learn unfamiliar disciplines 22 43 393 493.

He is protective toward people he considers his own. He promises Koneko protection, thanks Jeanne for caring for him during his recovery, supports Aisha, and repeatedly intervenes when allies or civilians are endangered 41 110 150 1013. He also favors practical diplomacy when conflict can be defused without further harm, such as mediating the dispute between Mikasa and a child's parents 1149.

However, Su Yang openly recognizes his selfishness and can be manipulative when pursuing a goal. He teases Amano Yuma while concealing his supernatural nature, uses calculated emotional approaches during sign-in objectives, and has prepared an automated posthumous countermeasure meant to destroy an enemy even at catastrophic cost 43 170 715. His confidence can become blunt arrogance, especially against opponents he considers fundamentally outclassed 531 803.
