Kaze Hikaru: Volume 4 (Manga)

In the year 1863, a time fraught with voilent social upheaval, samurai warriors of all walks of life flock to Kyoto with the hope of joining the Mibu-Roshi – a band of warriors united around their undying loyalty to the Shogunate system. In time, this group would eventually become one of the greatest (and most infamous) movements in Japanese history... the Shinsengumi!

Ordered by Katamori-sama to assassinate captain Serizawa, Captain Hijikata holds a secret meeting with the other leaders in the Mibu-Roshi to plan the murder of their charismatic comrade. Soji breaks in on the meeting, but rather than pleading for his friend's life, he offers to kill him.
