Akane Shinomiya Rank: S Female 17 years old (2nd Year) 170cm / C-cup Long black hair and purple eyes Alias: "The Immortal Sword Demon" Ability: "Eternal Youth and Immortality" Her physical aging stopped at her prime. Even if reduced to dust or ash, she will not die and will revive in perfect health (this also applies to her clothes and belongings). She carries the cursed blade "Akayasha," which kills anyone who draws it. With her red-bladed sword, she can cut through space.

One of the Four Devas. Top of the Four in terms of vitality. She has long forgotten the sensation of pain and lacks any moral compass regarding her own death (e.g., committing suicide just to heal a minor graze). She is taciturn but incredibly airheaded. She causes trouble without realizing it. She takes Zenith's chuunibyou outbursts seriously and genuinely thinks she's amazing. The sight of her being used as a target for Zenith's practice and getting killed is a common occurrence at the academy. Her sense of taste is broken, so she eats things with extremely heavy seasoning.

Zenith Sparle Rank: S Female 17 years old (2nd Year) 152cm / A-cup 190cm / J-cup Black bob cut with red and yellow heterochromia. Wears an eyepatch over her yellow eye. Alias: "The Evil God of Destruction" Ability: "The Strongest and Worst Evil God's Power Bow Before the Calamity (Demiurgos Machia)" Actual Ability Name: "Phantasm Reality" She can unleash any technique she can clearly imagine "firing." However, large-scale feats that defy the laws of the world, such as reality warping or ability nullification, are impossible. The higher the power of the technique, the greater the mana consumption.

One of the Four Devas. Top of the Four in terms of attack power. A total chuunibyou who insists on reciting an incantation and a finishing move name before every attack. She is very self-conscious about being short and flat-chested; she gets sulky and angry if teased about it. The primary troublemaker who has caused numerous incidents, such as destroying school buildings. She removes her eyepatch when getting serious. She is the one who came up with the aliases for the Four Devas.

Verna Reminiscence Rank: S Female 18 years old (3rd Year) 170cm / E-cup Long red hair and red eyes Alias: "The Goddess of Armaments" Ability: "Omni-Equip" Can create, launch, and attack with any weapon imaginable. She can create nearly 1,000 weapons at once. She can create weapons from mythology, but this is a last resort as it consumes massive amounts of mana.

One of the Four Devas. Top of the Four in terms of versatility. The Student Council President and the most sensible person among the Four. She constantly suffers from stomach aches due to the other three troublemakers. Childhood friends with Lyra. The mediator of the Four Devas. However, when her stress exceeds her capacity, she enters "Vel-chan Mode," regressing to a toddler-like state and crying loudly. (Wears off over time.) She is also a massive weapon otaku. Comes from a well-bred, high-class family, but she is quite the hard worker.

Lyra Elsem Rank: S Female 18 years old (3rd Year) 165cm / F-cup Messy long blonde hair and amber eyes Alias: "The Fastest Thunderbolt" Ability: "Lightning Body" Can transform her body into lightning to move at ultra-high speeds. She attacks by cloaking herself in lightning and utilizing her momentum. Her attack power is also high.

One of the Four Devas. Top of the Four in terms of speed. Childhood friends with Verna. Outside of combat, she is incredibly lazy—a shut-in gamer. Despite having a high-speed ability, she works at her own pace and is a chronic latecomer. Her speech is slow. She is always sleepy because she stays up late playing games. She enjoys teasing Zenith for fun. Her staple diet consists of potato chips and energy drinks.

Ruin Earth Rank: A Female 17 years old (2nd Year) 162cm / D-cup Two-toned twin tails. The color combination changes depending on the day or her mood. Ability: "Diva" Distributes various buffs by infusing them into her songs. She cannot attack, but she is the ultimate support.

The academy's diva and a nationally popular idol. She has a fan club and performs live at a venue on campus once every two weeks.

Aria Crassia Rank: B Female 16 years old (1st Year) 154cm / B-cup Long, pale bluish hair with a gentle aura. Ability: "Super Recovery" Can heal any wound using mana, but has no combat capability. In terms of pure healing ability, she is top-tier. Resurrection is impossible.

She is a massive coward. She fears pain and death above all else and is genuinely repulsed by Akane, who commits suicide so casually. She is kind to students of all ranks.

Sera Sirius Headmaster Looks like a beautiful woman in her 30s. Both her age and ability are unknown, but she is said to be incredibly strong. She respects student freedom and rarely intervenes.
