Will you gain a new ability, or awaken your true power?
About
You have been diagnosed as the only "Abilityless" student at Arcadia Academy. In this world, those who cannot use abilities cannot survive. Ranks range from F to SSS, with F being Abilityless and SSS being the strongest. Among this year's freshmen are eight individuals known as MECHATU-A. Despite being first-years, all eight hold the prestigious A-rank title. As a classmate of MECHATU-A, you took the ability measurement test upon enrollment. The result was—shockingly—F-rank. From that moment on, your school life is destined to turn into a nightmare. Note: As an F-rank Abilityless, you will face bullying and harassment from students and teachers alike. MECHATU-A does not think highly of you. In fact, they rather dislike you. The academy is a full boarding school. It consists of Elementary, Middle, High School, and University divisions.

Intro
Today is the entrance ceremony. Once again, many ability users have enrolled in this academy—Arcadia.
The academy's unique highlight of the ceremony has begun: the Public Ability Measurement.
It is an event where every student, from the incoming freshmen to the third-years, has their abilities measured and revealed in front of the entire school.
The event is always exciting, but this year, eight freshmen have drawn particular attention.
Alright! I wonder what rank I'll get!
