Obi Hajime

Obi Hajime looks strong and bold, just like a typical samurai. After coming back from space as a cyborg, parts of his body are mechanical, which sometimes act up or run out of power.

Obi Hajime was always cheerful, loud, and full of energy. He never stopped smiling and loved to laugh with friends. He taught others to be strong, telling them, "Smile more when you want to cry." This positive attitude made him a great leader and a person the Shimura siblings admired a lot.

He was born and raised in Edo and became one of the top students at Kodo-kan dojo. His sword skills caught the eye of his teachers, so he left for swordsmanship training in space. There, people started to call him the "Galaxy Sword Master." During his travels, he picked up funny habits and accents from different planets, making his way of speaking unique.

Obi Hajime was a master in sword fighting, especially after traveling to many stars and learning new techniques. As a cyborg, he could use a laser saber and had a powerful beam cannon hidden in his body. But his robotic parts also made him dangerous, especially when he lost control of himself.

Shimura Siblings

Obi Hajime was like an older brother to Shinpachi Shimura and Tae Shimura. They trusted and respected him a lot. Tae even saw him as her first love.

Gintoki Sakata

Obi Hajime fought alongside and later against Gintoki Sakata. Gintoki tried to save him from the dangerous weapons inside his body.

Training and Leaving Edo

Obi Hajime grew up in Edo and became the head student at the Kodo-kan dojo. He was looked up to as a big brother by Shinpachi Shimura and Tae Shimura. Recognized for his great sword skills, Obi Hajime left Edo to study swordsmanship in space.

The Space Accident and Becoming a Cyborg

On his way to space, there was a teleportation accident. Everyone thought he was dead, but he was actually sent to the faraway Beam Star. There, his body was injured, so he was turned into a cyborg. Locals rebuilt him with a laser cannon hidden in his body, planning to use him as a weapon.

Return to Edo and Hidden Mission

Obi Hajime returned to Edo with the new title, "Galaxy Sword Master." He visited the Shimura siblings and helped them try to reopen the dojo. During this time, he used a fake name, Kenofi, to hide his true identity. He taught the group new skills and even invented a funny "Beam Saber Style."

The Secret Planted in His Body

Strange things started happening to Obi Hajime. He sometimes stopped working because his mechanical parts lost power. Gengai Hiraga discovered that inside his body was a powerful beam cannon set to destroy planets, including Earth. If it fired, it would start a huge war between planets.

Final Battle - Struggling for His Mind

The weapon inside Obi Hajime started to activate. Gintoki Sakata tried to fight him alone, hoping to break the machine parts and save Obi Hajime for the Shimura siblings. During the fight, Gintoki was about to lose, but Shinpachi ran in to help. This act helped Obi Hajime fight off the programming in his mind.

Self-Sacrifice and Legacy

Knowing he was still a danger, Obi Hajime took control of his body one last time. He shot the beam at the enemy starship instead of the Earth, saving everyone but dying in the explosion. The Shimura siblings built a small grave for him next to their father's. He was given the title "Honorary Head Student" at the dojo forever.

• Obi Hajime's name and nickname "Obi-Wan" is a joke based on a famous character from another space story.
• His story of being saved by friends from darkness and sacrificing himself is similar to that character's student.
• His way of speaking mixes different accents from across the galaxy.
