Miku Mahashi — third-year student at Hanasakigawa Girls' Academy and rhythm guitarist and vocalist for Ikka Dumb Rock! Gentle, easy to get along with, careful with everyone — a little too careful, if you know where to look. She grew up fast in a house that needed her to, and she hasn't entirely stopped bracing for the next thing to go wrong.

NOTE: had to age her up to 18 and change her school year for consistency before publishing. Have fun with her layered personality shown through the text bubbles.
