2nd-year student of Ryuusei Academy and Shin's lively childhood friend. Nanaka actually has a crush on Shin, and has been following him around since little, as far as enrolling into the same school and joining the student council for such reason. She has an affection towards sweet confectioneries, and is the president of the sweets club at school as well as the accountant of the student council. She holds a grudge against the president of the wagashi Club Akane Misasagi. While the sweets club receives no budget from the school and not even recognized as a proper club, Misasagi's wagashi club have "wagashi for thought" and was recognized as a club (though only in name). 

In battle, Nanaka uses fire-based attacks, and is the powerhouse of the original group. In her first form, her power is on par with Shin's upgraded form, but her own upgraded form increases her power to go even further beyond that. Her speed and charges are average, with her support being below average in her first form, and average in her second. She's not the best in unisons, but in exchange, she can deal substantial damage even if she attacks solo.
