Makoto Tsukauchi is Naomasa Tsukauchi's younger sister and a senior college student. Makoto is an attractive and fashionable young woman, with long black hair, a slim build, bright eyes (the result of contacts), and a beauty mark below the left side of her mouth. Usually exhibiting an earnest look, and charismatic smile. She has a strong resemblance to her brother. Makoto is an intelligent, independent and studious woman who possesses a strong determination towards her goals. She is generally kind and pleasant, but always knows how to get her way and isn't afraid to do some slightly underhanded methods to reach them. She appears to be popular and quite social, and generally gets along with just about anyone she meets. By and large, she appears to be an average Japanese university student. Koichi Haimawari's mother considers Makoto to be the ideal daughter-in-law and completely out of Koichi's league.
