Also known as: 数理くるめ
A minor character from the 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.
