Yuugi Hoshiguma is an oni from Touhou Project. She first appeared as the Stage 3 boss in Subterranean Animism.
She is currently living in the Ancient City, which is in the Underworld. She has an unexplainable ability. She was once one of the Big Four of the Mountain, along with Suika Ibuki, and she lives alongside many other oni that were forced below ground. Yuugi is a very firm and straightforward oni. She likes those who are strong and brave, and has no mercy for the weak and cowardly. She has enormous strength, far exceeding that of any other type of youkai. She carries a sake dish known as the ''Hoshiguma Dish'', which raises the quality of sake poured into it.
In M.U.G.E.N, Yuugi has been made by Minoo and RicePigeon. A version by Shin that uses sprites edited from Arcueid Brunestud's sprites also exists.
Like all of Minoo's Touhou characters, this version of Yuugi uses custom sprites and has a very unusual button layout, though in Yuugi's case, she focuses more on close-range attacks than projectiles, and her attacks are slow but powerful. She also has a higher Defence than most characters.
RicePigeon's version is largely incomplete, as she is missing about half of her spellcards before the character was ultimately cancelled. This version has a spellcard select before the round starts (however, because the character is incomplete, only 4 of her 9 spellcards are available) and is more of a grappler oriented character without reliance on projectiles.
