Jiro

Jiro is one of the few characters to appear in every game.

Battle High: Team-Up
The former leader and founding member of Battle High. He stepped down when the organization was taken over. He vows to return and restore its righteous reputation.

Battle High: San Bruno/Elemental Revolt
Jiro is the middle child of the Ozawa family and has lived in San Bruno all of his life. Jiro and his younger brother, Shinji, have always been very close. Jiro always believed it was his duty to protect his younger brother no matter what; however, Shinji came to resent this over-protective quality. Upon entering high school, Jiro encountered "The Rivals" and was invited to join them, but refused, becoming an enemy, protecting students from the gang's grasp. Distressed and conflicted to hear Shinji had joined the gang, Jiro continued to secretly watch over his younger brother as he soon became the gang's leader. After a turbulent summer, Jiro returns to school as one of the gang's prime targets as it's commanded by his younger brother. He now must fight to survive his final year without ever giving up his duty of protecting those in need.

Battle High 2
Jiro had defeated his younger brother, Shinji, in a fight, ultimately disbanding the gang he led, The Rivals. Later that same day, Khai, a peer who was obsessed with defeating him, did so, but Jiro didn't care, happy his brother was out of trouble. Once the new principal was elected and students began losing their powers, however, Jiro began receiving strange texts from someone who mysterious referred to him as "your brother". At first, Jiro thought Shinji was pulling a strange prank, but as the texts became more threatening, Jiro knew he had to find his brother and warn him of the impending danger.
