Katsumi Hino (火野=克己, Hino Katsumi) is a Shinigami. Katsumi was once good friends with Mitsuru Inazuma and Sayaka Izayoi, with the three rebelling against Soul Society in Mitsuru's backstory. He would follow Mitsuru without question and went on nearly every mission with him, essentially serving as his right hand man. However, after Mitsuru's defeat of Eienrai, Mitsuru dissapeared to parts unknown, leaving Katsumi absolutely stunned and feeling betrayed. It was at this point that he decided to push himself to his limits and exceed the power of Mitsuru's Soul King Form, in the hopes that by seeing the mystical power being defeated by hard work and determination, that he could talk to Mitsuru once again. Katsumi is the main antagonist of Part I of Bleach: Second Rising.
