Uehara Himari is a second-year student at Haneoka Girls' High School and is the leader and bassist of Afterglow. She is a huge fan of Kaoru's. 

Himari is cheerful, good-natured, and is the band coordinator. She struggles to read the mood of a situation, which means she sometimes does things that have no effect. She's weak to tear-jerkers and sentimental episodes, and is fairly romantic. She is also weak to being teased, and tends to be clumsy and fall around at times.

She enjoys comparing the different sweets she buys from convenience stores and likes making them as well. She also likes cute things like clothing and stuffed animals, but wants to be seen as "cool" by others. Her ideas are normally teased or rejected - but her bandmates try to show support in their own way.
