A once-failed swordsman takes Kikyo's duty as a shrine maiden in the world of Inuyasha.
In the world of Campione!, he joins that "sword freak" in slaying Heretical Gods.
In the world of Noragami, he walks the world as a god, yet can cut down the power of gods without the slightest attachment, as a human.
In the world of the Holy Grail War, his own doubts will lead him to fight a red-clad boy, and he will also rebuke the stubborn fixation of a girl holding an invisible sword, a fixation that is anything but strength.
...The many things that happen along the journey are my life. Whether I reach the end or am still on the road, my resolve will not change.
