Synopsis

Setsuna Kai's been training hard at his elementary school's kendo club ever since his mother died, determined to get stronger in her memory. Problem is, he still can't beat his rival and best friend Mirai Kaname, no matter how much he practices. Then one day on the way home from practice, everything changes—a bizarre black fog rolls over Tokyo, the temperature drops, and the city gets buried in snow despite it being the middle of summer. When Setsuna gets back to his apartment, a kid suddenly crashes through his wall, shoves a wrapped box into his hands, and dies right there in his arms. Before he can even process what's happening, a demon shows up trying to kill him. Cornered and desperate to survive, Setsuna taps into some hidden power and manages to summon a demon of his own. The demon, a Cerberus named Cool, drops the bombshell that Setsuna is one of eight Devil Children destined to fight Hell itself and save the world from destruction. Setsuna's not thrilled about it, but his drive to finally surpass Mirai pushes him to accept the role. Turns out Mirai's a Devil Child too, so together they head into the Demon World to hunt down the other six and complete their mission.
