The protagonist of the "The Seven Choshoguns" arc is Buino Suzumu, the eldest son of the Shinsei Daishogun, who has grown up and been given the title of "Musha". He has been a tomboyish boy since he was young, to the point that even his amulet Goten has a hard time dealing with him. He neglects his studies and spends all his time practicing swordsmanship with the Sword Saint Vice-General and the Shinsei Shogun Gundam. As a result, his sword skills are incomparable to those of his peers, but he is dissatisfied that his father does not recognize him as a master swordsman, saying that he is still only half-baked. When the New Dark Army is revived and the Choshoguns set out to reach the Anaheim Mountain, he follows them behind his father's back. His special move is the Hien Tatsumaki Gaeshi, inherited from the Sword Saint. He can also summon Metal Garuda by shouting "Tenraihengen" and wear it as a golden feather robe.
