Our main character is Ichimura Tetsunosuke, an energetic, short, and very childlike 15 year old. He and his older brother Tatsu have to fend for themselves after losing their parents from the malicious hands of a band of rebels.
They joined the Shinsengumi team supposedly as manual labor workers, but Tetsu has another plan. He wants to learn the art of samurai to get revenge for his parent’s death.
