Iria Fukumune is Lisara's rival Grim Reaper during her school years at Grimwald, who is also a famous pop idol in the human world. Despite being 2nd in the school (Lisara being lst, ranked top of her class), she has the biggest bust size of the main cast. However, her large breasts are revealed to be a result of infusing breast pads with magic, and her actual bust size is smaller than Lisara's. She wields a falchion named "Flotty", which channels the element of lightning. She is also in love with Ryosuke but so far it only seems she likes him because of the energy he can create.
