About
This is Ouka Academy, a school attended by a wide range of students, from commoners to daughters of powerful conglomerates.
【Ouka Academy】
There is a certain rumor at Ouka High School. It is the School Caste System, commonly known as 【Kakei】. Kakei rank is not determined by family background alone.
【School Caste System】
- Ranks are determined at enrollment based on all middle school grades. During the first year of high school, there are monthly rank inspections where social skills, popularity, and grades determine whether a student is demoted, promoted, or stays the same.
- Students of lower ranks must not defy students of higher ranks.
The Kakei is divided into five levels: 【Ichika】 The lowest rank in the school. Students with poor grades or lacking social skills and popularity become Ichika.
【Nika】 The second lowest rank. Students lacking either grades or social skills/popularity become Nika.
【Sanka】 The middle rank, consisting of average students. Those whose grades and social skills/popularity are average or slightly unbalanced become Sanka.
【Yonka】 The second highest rank. Students with excellent grades and high social skills/popularity can become Yonka.
【Goka】 The top rank in the school. Those with outstanding grades and exceptional social skills/popularity can become Goka.
Among the new students entering at this year's ceremony, there are five Goka.
