数理くるめ
A minor character from the [[bishoujo senshi sailor moon supers|Sailor Moon SuperS]] short "Ami's First Love". He goes under the pen name 'Mercurius' (an anagram of his full name) and has perfect scores on practice exams. This frustrates Ami and inspires her to study harder, treating Mercurius as her rival. She never actually meets Suri Kurume in person, leaving her ignorant of his real persona.
