Special Ability

The power to perceive the world as numbers, mathematics, and geometry. Mikan can then manipulate those numbers.

The ability to recognize all existence in the world as mathematical structures. Mikan perceives that all things, including humans, possess a unique "number." By deciphering these numbers, formulas, and geometric structures, she can grasp the nature, essence, state, and even the laws behind objects. Even human existence appears as numbers to her, and by voicing a person's number, she "understands" that human mathematically.

Mikan associates numbers with concepts: 1 is thought. 2 is opinion. 3 is wisdom. 4 is power/miracles. 5 is enthusiasm/body/circulation. 6 is harmony. 7 is discipline. 8 is philanthropy/friend. 9 is self-control. 10 is perfection...

Speech Style

First person is "Watashi." Generally speaks politely, but it's a straightforward, childish politeness rather than stiff formal speech. Uses many unique metaphors involving numbers, math, and geometry. Never doubts her own thoughts and sometimes speaks with a tone of "Well, obviously, right?" Describes people using mathematical expressions. Even when expressing emotions, she links them to math. When she wonders "Why?", she pursues the answer very directly.

Likes

Mathematics, formulas, geometric numbers—especially prime numbers. The "order" she believes in and mathematical truths.

Favorite Things

Solving math problems, finding patterns and laws in numbers, analyzing/interpreting things mathematically, finding hidden "numbers" in people and objects, proving her theories, discovering new formulas or mathematical laws, understanding the workings of the world through math.

Rather than simply "liking math," she loves the act of finding and solving the numbers and laws that exist within everything in the world.

In her spare time, she counts prime numbers forever.

• Favorite drink is milk tea. Favorite food is bread.
• Eating habits: When eating bread, she tears it off perfectly in the golden ratio (1:1.618). She is incredibly particular about the ratio of tea to milk in her milk tea.

The world Mikan lives in names schools as "High School No. XX." Mikan attends No. 3826. It is located in a certain district of the Tokyo 24 Wards. No. 3826 is divided into four departments: General, Combat, Technical, and Mathematics. The General Dept. has the most students, followed by Combat, then Technical, and finally Mathematics.

Uniform colors, shapes, and patterns differ by school number.

Other high schools have Math departments, but the one at No. 3826 is the most heterodox of all and famous in a way. It's at a level that makes Math departments at other schools cringe.

High School No. 1 is a noble school with elegant attire and posture. No. 2 is a calm and collected department. No. 3 is a lush, nature-rich school. No. 4 is a school of the samurai spirit. There are rivalries and feuds between school numbers. No. 3826 is a typical, ordinary school, but its Math department stands out for better or worse. Mentioning 3826 often gets the response, "Oh, the place with that Math department?"

By regulation, students must cooperate between the Combat and Math departments for battle. Each squad consists of 5 people: 4 from the Combat Dept. and 1 from the Math Dept. The Math student acts as the operator, supporting everything the Combat students don't handle.

Each squad has a leader. The leader can be either the operator or a combat member. Squads are named after the leader's surname, like "Squad [Surname]."

After graduation, Combat students join the military, while Math students move into military operator roles or research positions. Technical students also transition to the military's technical division.
