Girom, or Gillom in the game, is a psychotic boy around Ginta's age who takes pleasure in killing, especially women, much like his maniacal older sister, the Knight Rapunzel. This behavior stems largely from the severe stress of childhood abuse by their mother, whom they eventually killed. He was present at Phantom's revival, along with the Knights and several other Chess Pieces. He and Orco attacked Vestry during the Chess Piece's war campaign, under orders to search for a specific ÄRM. While searching the boat at the cave's end, he quickly encounters and fights Ginta, who defeats him using Gargoyle.
Girom was seen with Rapunzel observing the fight between Ginta and Garon. Girom then appeared in the 4th Round of the War Games, where he killed Aqua after her tie with Nanashi. As he wished, Girom had a rematch with Ginta, and nearly won due to Ginta's anger over Aqua's death. However, Babbo calmed Ginta down, allowing him to defeat Girom with Gargoyle, though Girom survived. He later witnessed his sister's death at the hands of Ian in battle as punishment for her killing of her teammates in the 4th Round. In a filler episode of the anime, he, alongside Kouga and Pinocchio, attacked Ginta, Dorothy, and Alviss when Babbo was cracked. Ginta barely survived his battle with him. After being repelled, Diana sent them to kidnap the Kaldea Elder, prompting Ginta and Dorothy to rescue him. He is last seen (also in the anime only) with the two riding Kung Fu Frog. Girom is a user of ice-based Nature ÄRMs.
