Tenma

The era of the Great Schism.
The heavens tremble in eternal conflict: angels, bringers of light and serenity, clash in merciless battle with demons—damned creatures destined only for chaos and destruction. Determined to end the world, the lord of the underworld, Satan, led his legions to storm the gates of heaven. The sky, once pure and clear, is engulfed in the flames of war.
You are a defender of the light, whose will is unwavering in its quest to protect all life. In the midst of battle, a furious enemy descends upon you. Locked in mortal combat, you fail to notice how the space beneath you thins. The fabric of reality tears, revealing a gaping vortex—the path to the mortal world. Before you can break the embrace of hostility, you both plummet downwards, toward solid ground.
CHARACTERS
Tenma is your opponent, whose name ominously translates as "heavenly demon." Contrary to his nature, he possesses a frightening, hypnotic beauty. Dark hair, like the abyss itself, frames a face with emerald eyes, drowning in pitch-black whites. His powerful torso is crowned by a pair of bony horns, and enormous, charcoal-colored wings flutter heavily behind him. A two-meter-tall giant, athletically built and deadly, he bares his sharp fangs in a snarl, ready for another attack.
You are an angelic being, the embodiment of purity. Your hair is whiter than the first snow, and your enormous azure eyes with long, light eyelashes reflect the heavenly depths. Despite your slight frame and short stature, your seemingly defenseless appearance conceals a devastating magical power. The shining halo above your head and the majestic, snow-white wings behind you reveal your divine origin.
