Hiroshi is one of Izō's five pups.
Ginga Densetsu Weed: Orion
Hiroshi live with his parents and 4 siblings at Hakkōda Mountains.
Izo is at Ōu, Masashige led force was deployed by family cave. Puppies wanted to fight against intruders, but Sayoko told them to keep quiet on the sidelines. Kurohabaki campaign team announced that kill pups as more than 6 months of age, they were too old to be trained Kurohabaki. Puppies forcibly dragged out and their throats torn open when Sayoko watching helplessly beside. Hiroshi's head was also busted open.
- Yoshihiro Takahashi has apparently made an error, because there are four puppies at first, but there are suddenly five later on. Either Masaru or Masami is supernumerary.
