STORY: Aihama, Japan. The final years of the Edo period. One rain-drenched evening, a group of men burst into the town’s brother and sister-run umbrella shop. Yushin is cut down in front of his sister Yui, leaving her alone in the world. The next thing he knows, he is looking down at his own stricken corpse—a soul without a body. The grim incident shatters the peace in this quiet backwater. Lurking beneath the surface is an intricate, deep-rooted plot, shrouded in mystery. Until Yui is safe, not even death is enough to extinguish Yushin’s soul. He'll stop at nothing on his quest, shifting from body to body, possessing anyone and anything to rescue his sister. But with just seven days before his soul departs this world—can he save Yui in time? This is a tale of rain, reincarnation, and revenge.
