If you're not drawn to the mystical realm of the "Unseen World", Suiten, a town in Kyushu, may seem uninteresting and unworthy of a vacation. Yet, for Taro, Makoto, and Masayuki, three young boys tackling their personal struggles, Suiten provides a gateway to an alternate dimension. However, the Unseen World is anything but ordinary; it's a land inhabited by ghosts, and recent events have created a portal for departed souls to cross into the physical world. Embark on a journey with Taro, Makoto, and Masayuki as they navigate this perplexing domain in search of solutions.
