Ideal type, what ideal type, big sister is the ideal in the world! After finally catching up with his eldest sister, an accident at the Paranormal Research Society pulled him into another world of "spells". In order not to involve his sweetheart, he reluctantly broke up with her. - However, he didn't expect that he would see his ex-girlfriend again when he was dying.
