November 4 in Japan is unofficially celebrated as "Good Butt Day (Ii Oshiri no Hi)", derived from a pun on the Japanese writing of the date. The number 11 represents a double “i” (いい = good), the number 0 represents a letter “o”, and the number four maintains its pronunciation as “shi”. To the latter, the “ri” is added to create “ii oshiri (Good Butt)“, which gives rise to this peculiar celebration. And on this occasion we are joined by Lillandra, the self-proclaimed Demon Sworn Princess of the Seventh Circle of Hell (She isn't really, she's just a mutant, but go along with it).
