|“||The powers of Earth, Water, Fire and Wind. Devouring the souls of Dragon and Demon, Beast and Deity. Destroy these loathsome bonds!||”|
—Inverse Fiends, H Episode 37
The first two members of the group, Sofia and Shido, were recruited and served under Ikazuchi at the beginning of Future Card Buddyfight Hundred. For the majority of the season, they performed various acts under Ikazuchi's order in order to satisfy both his and Yamigedo's hunger.
After a series of events, such as Gratos's appearance, Noburu's kidnapping, and Ikazuchi's loss to Gao and disappearance, Gratos took over the role of Leader of the Hundred Demons and began to put into motion Yamigedo's revival. He began by using "Tiger" to defeat prominent Buddyfighters in the area of Cho Tokyo and, should their skills impress them, they would be kidnapped, brainwashed and turned to stone until they were needed.
Davide Yamazaki was recruited as a result of a chance reunion between him and Shido. After finding out Kiri's true origins and his subsequent loss towards him, he decided to offer his services for a chance at revenge.
In H Episode 37, all of the members were used for their intended purpose and with their powers combined, managed to thwart the Omni Lord's Sealing Ritual. With that, Yamigedo was able to successfully metemorphise into his most powerful form yet.
