The Imperial Seal has been passed down through the generations since ancient times. It confers great power unto the warriors that it chooses. This is the story of those warriors. It is a time of chaos and of civil war. It is a time when great armies clash in titanic battles and great heroes carve their names in history. It is also a time of death and destruction, when the people of the land live in constant fear of the sword. Onto this stage steps the reluctant Rikuson (Lu Xun), whose family had been the guardians of the Imperial Seal up until it was stolen by Sonsaku. At the behest of his mentor Rikuson offers his services to Sonsaku with the intention of confirming the will of the Imperial Seal. However, assassins strike down Sonsaku and the Imperial Seal is lost. So begins, Rikuson’s journey to recover the Imperial Seal and discover his destiny.

As the world is in the middle of an industrial revolution, a monster appears that cannot be defeated unless its heart, which is protected by a layer of iron, is pierced. By infecting humans with its bite, the monster can create aggressive and undead creatures known as Kabane. On the island Hinomoto, located in the far east, people have built stations to shelter themselves from these creatures. People access the station, as well as transport wares between them, with the help of a locomotive running on steam, called Hayajiro. Ikoma, a boy who lives in the Aragane station and helps to build Hayajiro, creates his own weapon called Tsuranukizutsu in order to defeat the creatures. One day, as he waits for an opportunity to use his weapon, he meets a girl named Mumei, who is excused from the mandatory Kabane inspection. During the night, Ikuma meets Mumei again as he sees Hayajiro going out of control. The staff on the locomotive has turned into the creatures. The station, now under attack by Kabane, is the opportunity Ikoma has been looking for.

The world is in the midst of the industrial revolution when horrific creatures emerge from a mysterious virus, ripping through the flesh of humans to sate their never-ending appetite. The only way to kill these beings, known as "Kabane," is by destroying their steel-coated hearts. However, if bitten by one of these monsters, the victim is doomed to a fate worse than death, as the fallen rise once more to join the ranks of their fellow undead. Only the most fortified of civilizations have survived this turmoil, as is the case with the island of Hinomoto, where mankind has created a massive wall to protect themselves from the endless hordes of Kabane. The only way into these giant fortresses is via heavily-armored trains, which are serviced and built by young men such as Ikoma. Having created a deadly weapon that he believes will easily pierce through the hearts of Kabane, Ikoma eagerly awaits the day when he will be able to fight using his new invention. Little does he know, however, that his chance will come much sooner than he expected...

Keiichiro, a young man who lives alone in his house, went through a lot of pain in his life, since the tragic car accident that killed his parents and younger sister, blaming himself for surviving.One rainy day, he seeks shelter in an old shrine. There he notices a little girl, sitting on a chair, surrounded by garbage. She herself is garbage — an abandoned android dumped here by someone, holding a sunflower in her hands. Stricken by sudden sadness, he takes her with him to an android repair shop, where he is told that she will never function. So returning home, he dumps her in the dirty bathroom. Waking up the next morning, though, Keiichiro finds the little android girl standing in the kitchen, preparing breakfast. Still without a name — remembering the sunflower — Keiichiro names her Flower. And so begins the life for these two unlikely protagonists.
