This is a complete summary of the story of the Devil Children manga.

Chapter 1: AD 2000.7 Early Winter

The story begins in Ice Land, where a nameless deliveryman flees a horde of Nightmare Demons while carrying a parcel. The man fears he is running out of time, exclaiming the parcel is meant for the Devil Child who will gather the "seven horns" and save the world.

Meanwhile in the Real World, the date is July 31, 2000, 2:06 PM. Setsuna Kai loses a kendo match against Mirai Kaname, sparking a heated argument between the two. Their friend Zett Takajō tells them to stop fighting, and reminds Setsuna that his mother Tsubomi is watching over him. Zett refers to Setsuna's pendant, a memento of his father which his mother gave to him as a child just days she passed away. Since then, Setsuna has vowed to become strong.

As the three walk home, snow falls upon the city, which has been happening across the world since the day before. Setsuna wonders if it is the work of ghosts, but unbeknownst to the kids, the Nightmares from Ice Land secretly observe them. Setsuna retreats to his apartment to warm up, when suddenly, the deliveryman crashes through the wall, hands over the parcel, and dies. Nightmare then enters the apartment, addressing Setsuna as the Devil Child possessing a Messiah's Horn. Grabbing a broken piece of wood, Setsuna strikes Nightmare's neck, only to have it turned against him and stabbed through his heart. Nightmare takes the Messiah's Horn, the true name of his father's pendant, causing Setsuna to erupt with rage. As a pentagram flares on his forehead and his wounds get miraculously healed, he quickly reaches for the parcel. The packaging erupts into flames and transforms into a Deviliser, which Setsuna fires at Nightmare, blasting him out of the apartment.

In firing the Deviliser, Cool the Cerberus appears before his new master. He tells Setsuna that the unnatural weather is due to Demons from Makai, the Demon realm, and how Makai and the Real World are both in peril. To save both worlds, a Devil Child must gather the seven Messiah's Horns. Setsuna is reluctant to fulfill such momentous duties, being a mere elementary schooler, until Nightmare returns to fight. Cool gets injured by Nightmare's Zan spell, calling for his master to be brave and hone his powers. Motivated by wanting to become stronger, Setsuna opens a rift to Makai using his Messiah's Horn, while Cool fights back by casting Agi. With Nightmare defeated, Setsuna and Cool leap into the Makai rift. Mirai overhears the conflict and smirks, knowing that things are now in motion. As for Zett, he sees explosions coming from his friends' apartment complex, and enthusiastically says "Game Start."

Chapter 2: Excessive Expectations

Setsuna has a faint flashback to his childhood, wherein he was beaten up by bullies and wanted to kill them. He has a brief memory of young Mirai, until Cool distracts him and welcomes him to Makai. The rift brought them to Ice Land, which Cool claims is Makai's sixth stratum. Standing before the Ice Gate, or the "Door to Hell" as Cool puts it, Setsuna learns that by using a Vinecom, he can load Demons into his Deviliser's Memory Bullets and summon them. The two march into the Ice Gate, declaring they will save both Makai and the Real World. In the distance, another Nightmare and his Demon gang discuss how their master, Hel, said there are three humans in Makai. Suddenly, their attention gets directed to Mirai, who has entered the Demons' realm carrying a Deviliser.

Setsuna and Cool arrive in Frost Town, to which Setsuna exclaims how Makai is a lot less grim than he had imagined. Taking a lunch break, Cool further explain his master's importance, in that only people with power like Setsuna's can use the Messiah's Horns―the one Tsubomi gave him is the Rainbow Horn. There are seven in total, which must be combined with the seven Messiah's Eyes to form the Norn Keys, items capable of bending reality to the wielder's will. However, the remaining horns are scattered, and Cool fears that the world is doomed if the Great Demon Lord acquires them. Setsuna feels overwhelmed at first, but realizes his missing father and Makai must be related somehow, seeing as he previously owned the horn. Cool tries asking more about his master's father, but Setsuna explains how his father left before he was born and thus never got to meet him.

The duo approach a lopsided inn on Frost Town's outskirts, when Setsuna is nearly hit with a bolt of magic, and the Demon gang descends upon them. Cool prepares an attack, only for the Demons to lift the inn off the ground and throw it on top of him. One of them pummels a distraught Setsuna and takes his Deviliser, putting to his head as he declares he has no chance of escaping Makai alone. Luckily, Mirai leaps in and takes Setsuna's Deviliser, teasing that he is a lousy Devil Child. She then calls her own partner Veil the Griffon, whose skills tear the enemies to bloody pieces. Setsuna throws a fit after the battle, knowing Mirai is also a Devil Child and he will not save the world solo, proving she is better than him yet again. Cool recognizes Veil and is equally as surprised. However, the kids notice they are surrounded by a crowd of Demons, who take them away to Hel's castle.
