Story
Badigadi appears as early as Rudeus's wedding feast, where, making merry, he carries Julie on his shoulder. In the final war, in repayment of an old debt, he agrees for the one and only time to take the Hitogami's side: the Hitogami asks him to kill Rudeus and Orsted. Badigadi carries Geese on his shoulder and effortlessly presses back even Atofe and other demons.
In the decisive battle Rudeus, in the Magic Battle Armor (tempered by training with Orsted and Eris), holds him off and severs his arms, placing them in special seals where they do not regenerate, which causes Badigadi himself to shrink. In the end Orsted seals him — but does not kill him, at Kishirika's request; sealed away along with him are both the Battle God's War Armor and the Royal Dragon Sword.
Orsted offers the defeated Badigadi a chance to abandon the Hitogami and swear fealty to him, but he flatly refuses — not out of loyalty to the Hitogami, but because his “one time” of war is over and he no longer fights for anyone. He agrees to wait patiently in captivity: when — a hundred years or so hence — Orsted's war with the Hitogami ends, there will be no more point in holding him, and he will be released.
