Kiyoko Tatsuhara

6
Several years ago, Kiyoko Tatsuhara was a student at Akademi. Because of her strong sense of justice - and her tall, muscular build - the Student Council President identified her as a perfect candidate for the role of "Enforcer" on the Student Council. She eagerly accepted the position, and for the next three years, Kiyoko worked tirelessly to make Akademi a safe and peaceful place.
Although the primary purpose of Akademi is to be an educational institution, it also serves a secondary purpose for the organization that funds it - Saikou Corp. The premise of "an elite school for gifted young prodigies" provides Saikou Corp with a convenient way to gather talented people in one location where they can be observed and judged. If Saikou Corp determines that a student has exceptional skills and would be an indispensable employee, they are invited to join the company immediately after graduation. Many young men and women with genius-level intellect have been recruited into Saikou Corp this way.
However, intelligence is not the only metric that a student is judged by. Kiyoko's grades were lower than most, but her personal values, physical stature, and years of experience keeping Akademi safe made her a prime candidate to become a security guard at Saikou Corp.
