"Once the leader of a notorious group of bandits and could subdue an Oni with his bare hands! After being defeated by humans, he blamed it on his large consumption of alcohol and now has switched to sports drinks."
Thurston has tan skin, messy blonde hair with brown tips on the top spikes and the hanging part, small canine teeth, eyes with black sclera and green irises, and short dark sharp claws on his hands and feet. He wears a red mask with horns, a golden tan bead necklace, a red ragged vest cloak with white ends held by a dark teal sash, and navy blue hakama pants. He is seen holding a large dark blue-grey slender bowl on his right hand and a bottle gourd on the left. As he does not wear shoes, Thurston is always barefoot.
The holder recovers HP when they deal critical attacks.
Thurston is based on the legendary oni king Shuten-dōji, which is a nickname meaning "little drunkard". He is noteworthy in being one of Japan's three most evil youkai (Japanese: 日本三大悪妖怪,Nihon San-dai Aku Yōkai), along with Emperor Sutoku, who, depending on the source, either turned into a daitengu or an onryō, and the nine-tailed kitsune Tamamo-no-Mae.
There are many versions to his story, but the most commonly accepted one is that he was not born a youkai, but instead an alleged "devil child" who was feared and scorned for his exceptional intellect and physical strength. Abandoned by his own mother, he was adopted into a monastery but was treated in the same way by his peers, which made him drown his sorrows in sake and grow to despise humanity, until he became a full-fledged youkai. In particular, one version says that during a festival he donned an oni mask to scare the other monks, but then later found that he could no longer remove it.
Retiring to Mt. Ōe, he learned dark magic and assembled an army of oni and other youkai, with which he terrorized Kyoto for years, even taking up a right-hand oni by the name of Ibaraki-dōji, until Shuten-dōji was finally defeated by Minamoto no Yorimitsu.
Thurston is a combination of "thirst" (referring to Shuten-dōji's name meaning "little drunkard") and the name "Kurston".
