A long era of war finally came to an end, ushering in a new age. But this new age was far from peaceful—twisted souls of the countless dead, born from the chaos of war, had taken monstrous form as Mikubi, manifestations of malice that spread fear among the people. In these troubled times, a boy named Tsubakuro, who holds the one and only power capable of defeating the Mikubi, sets off on a journey in search of the memories of his father, who was devoured by one of them— Thus begins a tale of memory and bonds, a Japanese-style battle fantasy!
