Relationships[edit | edit source]
Mentor[edit | edit source]
- Shimura Ken: Hajime looks up to Shimura Ken. He modestly claims that he couldn't be compared to his mentor. He regrets abandoning the school and leaving Otae and Shinpachi to carry the burden of protecting the Dojo on their own.
Students[edit | edit source]
- Shimura Shinpachi: He views Shinpachi as a student and as his little brother, often referring to him as Shin Boy.
- Shimura Tae: He views Otae as a student and a sister. He is unaware that he is Otae's first love and initially believes that Gintoki is her boyfriend.
- Sakata Gintoki: He views Gintoki as a student and as a member of the saber style, much to Gintoki's dismay. He uses Gintoki as an example to attract customers by claming a fight with him in front of everyone. He made Gintoki his partner as he calls him Coach Sakata in Lesson 404.
Story[edit | edit source]
Beam Sword Style Arc[edit | edit source]
He comes back to Earth after he claims that there were no opponents to fight. He visited his mentor's grave and met Otae. Otae wanted to reopen the dojo to teach Tendoumushin style with the beam saber. She recommends Obi to be the head coach, Shinpachi was happy to meet his older brother again.
Later on in Lesson 404 it was revealed that he has a laser canon placed on his person by the amanto. According to Gengai, he contains an interstellar beam canon that will activate and fire when a league of planets line up. It would be like earth declared war on the whole galaxy.
Gintoki planned to bring Obi back to Shinpachi and Otae but his Kenofi persona resisted him.
Shinpachi and Kenofi dueled with Otae as a judge. Obi regained his body as he remembered his past while Shinpachi charges towards him.
As Shinpachi and Obi dueled, Obi was cut down and Shinpachi was the victor but Shinpachi was sure that Obi allowed him to win just like in the old days. However Obi said he was serious and he heard Shinpachi, Otae and Gintoki's voice that allowed him to return to Edo with pride knowing what true strength is.
He left Shinpachi and Otae to Gintoki, he intended to fix the problems he left. He saved Edo by aiming the beam cannon in his body at the Biimu ship. Both the ship and Obi's body destroyed each other and Obi's last thought was his time with Shinpachi and Otae.
His grave is placed next to his mentor Shimura Ken.
