A 13-year-old half-Japanese, half-British Earthling summoned to the alternate world of Flonyado, the Kingdom of Biscotti Republic as Princess Millhiore's "Warrior". He wields the Divine Sword of Biscotti, Palladion, a weapon that can assume different forms depending of its owner (in Cinque's hands, it becomes a staff). He has a cheerful and straightforward personality, always going at his own pace. Athletic and acrobatic, he loves sports as well. Was a first-year middle school student in Japan's International School prior to the summon. He can fire destructive energy beams from the tip of Palladion. Seems to have feelings of attraction towards Millhiore.

Note: Official romanisation of "Cinque" was taken from New Type publication.
