An artificial musha created by Bakuryu Gundam based on the Kidou Musha Daihagane. He has a will of his own and a friendly personality, but when he gets angry he transforms into his long-limbed Kongou Haganemaru Form and goes on a rampage, losing his mind. He and Godmaru are best friends, having trained together. He is quite skilled in the Kijin Tetsukenryu style, but as he fights while suppressing his anger, he is unable to show his true strength. However, when Godmaru and the others received artifactls from Tengaio, Haganemaru was also given a mysterious power, which allowed him to not lose consciousness even when he transformed into Kongou Haganemaru. He can also transform into the flying form Mega Shooter, and can fly with Godmaru on his back. When disassembled, it can be used to power up the The Five of Touha Mushas.
