Hana (ハナ Hana?), like Saya, is one of the 'girls-in-training' under Akesato. She is the polar opposite of Saya, being very loud, blunt, upbeat and caring in her own strange way. She dislikes katanas. Her father was an umbrella maker and spoke loudly about honor. When her mother was sick, he did not sell his swords for a doctor. What happened to them is unknown but it is assumed that the mother died of the illness. She wants Tetsu to make her his new mother out of compassion. She has a big crush on Sanosuke after he saved her from thugs at a festival.

Although traumatized by witnessing the murder of his parents by one of the Choushuu, Ichimura Tetsunosuke's thirst for revenge lead him to desire strength. At the age of 15, Tetsunosuke approached the Shinsengumi, wanting to become one of its members. However, Tetsunosuke lacked the skill, mind and will to emotionlessly cut down whoever threatened peace and the Shinsengumi. Even with the support of his brother Tatsunosuke and his newfound friends of the Shinsengumi, little did Tetsunosuke know the blood and pain he would have to face being part of this historical group.
