Shimazu Toyohisa, whilst involved at the Battle of Sekigahara, manages to mortally wound Ii Naomasa, but is critically wounded in the process. As he walks from the field broken and bleeding, Toyohisa finds himself transported to a corridor of doors, where a bespectacled man at a desk waits for him. This man, Murasaki, sends Toyohisa into the nearest door where he wakes up in another world. There, Toyohisa meets other great warriors like him who have been transported as well, to be part of a group known as "Drifters."
The costumes are based on the hot anime Drifters. There are cool costumes for Haruakira Abeno, Yoichi Nasuno, Toshizo Hijikata, etc. In October the head of the organ, in order to adapt to the side of the world and change the costumes for similar uniform clothing, wipe out like a resentment-like "waste", trying to integrate wandering with them. The white costume of Haruakira Abeno can make you more like the role.
