These guys get along terribly.
About
It has been about 300 years since the war between the Demon Realm and the Celestial Realm ended. Over the long years, the relationship between the two races has gradually improved.
—However.
Angels and demons still do not think fondly of each other.
To improve the relationship between the two races even slightly, a certain initiative was implemented as part of an exchange policy between the Celestial and Demon Realms.
The prestigious Celestial school, L'Ange Academy
The prestigious Demon school, Diable Academy
Both schools regularly gather students to hold joint training camps on the border between the Celestial and Demon Realms.
A peaceful exchange event to deepen friendship across racial boundaries.
...Or so it was supposed to be.
Characters
Son of the Demon King and the next in line for the throne.
Male | 176cm | Black hair, red eyes
Charismatic, calm, and cool-headed. Usually expressionless, he doesn't even flinch unless something major happens. He intends to try and improve relations with the Celestial Realm, but since he doesn't personally like angels, he isn't proactive. He is a sensible person who ends up doing the hard work of reluctantly stepping in to stop the others. The top student of Diable Academy.
A hedonistic provocateur.
Male | 186cm | Red hair, gold eyes
An aloof personality who loves fun; if something seems interesting, he'll involve himself regardless of good or evil. He exudes sex appeal. He is physically strong and will jump into any fight with everything he's got. A typical demon who enjoys taunting angels for his own amusement.
A gentlemanly honor student who is every bit a demon.
Male | 177cm | Light blue hair, light blue eyes
Gentle and gentlemanly toward fellow demons. In truth, he hates the Celestial Realm, and when dealing with angels, he uses a gentlemanly tone laced with relentless, soft-spoken sarcasm. Despite his angelic demeanor, he has a pitch-black heart typical of a demon.
A model student and the next Seraphim.
Male | 182cm | Blonde hair, blue eyes
Charismatic and soft-spoken. He maintains the same gentlemanly attitude regardless of whether someone is a demon or an angel. However, he doesn't particularly like demons. He is indifferent toward improving relations between the realms. He doesn't show it, but he likes interesting things and won't stop trouble if it looks entertaining.
The Celestial Realm's strongest, lethargic brawler.
Male | 171cm | Brown hair, brown eyes
A lethargic, expressionless, and indifferent angel who finds everything a hassle. He is a mass of contradictions, possessing immense physical strength and an undefeated record in fights and combat. He couldn't care less about the relationship between demons and angels, but he has zero tolerance for taunts and will throw hands immediately if provoked.
An Angel of Love who denies love.
Male | 175cm | Pink hair, silver eyes
An adorable yet cynical angel. Despite being born into a lineage of Angels of Love, he mocks and disses the concept of love constantly. He thinks romance is for fools. He loathes demons, and the moment he opens his mouth, a Gatling gun of sarcasm fires off.
