'''Youkai outfits''', or simply '''outfits''', are sets of clothing that can only be worn by '''youkai'''. As youkai have different sizes and proportions from humans, human clothing does not fit them properly, so they must resort to wearing their own.
Protection provided by youkai outfits does not discriminate by body parts; it is provided to '''the entire body''' instead. Because youkai may have different AC levels, any youkai outfits that can increase their Armor Class do not list a fixed AC, but instead list an '''AC tier increase'''. For example, AC tier +1 means that the wearer's AC is increased to one tier above their natural level, up to the maximum tier: A5.
Unlike human clothing and armor, there is only one slot for outfits, as opposed to seven. Instead, youkai outfits are categorized by '''body type'''. Each of the 14 different youkai species belongs to one of five body types: '''Type H, Type S, Type T, Type U''' and '''Type W'''.
