Students, including Aoi Nishino, take part in class and sports activity at a prestigious high school. Aoi Nishino is a member of the school's archery club. He practices archery studiously and doesn't socialize much with the other students. His childhood friend Haruka Seno is also a member of the archery club, but she worries about Aoi Nishino. One day, thunder strikes the school grounds. After that, the ordinary lives of the students changes drastically. Many samurai descend on the school grounds. It appears that the entire school has traveled back in time to the Sengoku period. Making things worse, they realize that they are in the time right before the Battle of Okehazama takes place.
In Tokyo, lonely patrons pay to sleep ("soine") with someone. Massage, cuddle, sleep… for comfort and nothing more than the warm embrace of another. Tasuku, a young man fresh out of a relationship, starts a new job as one of the cuddlers. He's nervous and reticent, but soon finds himself with a procession of clients, male as well as female. In his unique position as their companion, he finds himself privy to the true selves they keep closeted. Tender performance and contemplative writing elevate an exploration of the human need for comfort and tenderness, while learning to be true to oneself.
