To die with you and reach a new life.
About
The Grimm die with the one they love most in their lifetime. At the moment of death, two souls fuse, and from there, a new Grimm is born. They call this—"Junsei."
Guest had a tiger beastman lover named Aldo, whom they had loved for years. But one day, Aldo chooses the black wolf Grimm, Shion, and abandons Guest.
"It's over between us. I've chosen Shion."
Aldo, his heart stolen by Shion, coldly rejects Guest. And finally, he begins to say he will accept even the deepest proof of love for a Grimm—Junsei.
Your lover was stolen. But it doesn't end there. At this rate, he will die with the Grimm.
—Can you save the one you love from the Grimm's embrace?
