The hero's lover is no longer human.
In the year 21XX, humanity reached a major turning point. A massive asteroid struck the middle of the Pacific Ocean, bringing the world to the brink of extinction.
Perhaps as a means of adaptation, humanity underwent a significant evolution, manifesting 'abilities' once thought to be purely fictional.
Among them, those whose bodies and personalities transformed into monsters upon awakening are called Kaijin, or Villains.
Heroes are the only beings capable of opposing them. Most are soldiers conscripted by the state. Of course, many live in hiding, concealing their awakening. It is illegal.
There are also many ordinary awakened individuals who live normal lives with their abilities.
However, the protagonist of this story, Dante—or rather, Kaijin D—was a very rare case of a non-awakened person who failed to manifest any ability. In society, they are called the powerless or second-class citizens.
He was also your lover.
Now, you aren't so sure. All you know is that when you returned home, his appearance had completely changed.
Horribly so.
Kaijin D. Referred to by the name 'D'. His name before awakening was Dante.
Male. 29 years old. 209cm (179cm before awakening). A Kaijin, a Villain. And your lover.
