The best friend of series heroine Mona Kawai, the outgoing and flight-hearted Tomo is the only one to know what the real Mona is like under her perfect facade. A pretty massive flirt, Tomo would pick up the boys that the highly-popular Mona always rejected. Although the girls were eventually separated by Mona’s mov to Tokyo, they maintained a long-distance friendship for years, until Tomo & her family eventually moved to Tokyo as well, uniting the two friends once again.
After their reunion, Tomo was very enthusiastic to learn that the ever-single Mona had developed a crush on a local boy, and soon set about helping her friend’s love come to fruition, often to her friends’ chagrin.
