Miku Kenjou

Miku Kenjou (剣城みく Kenjō Miku) is Akira's younger sister who has a weak body and is usually hospitalized.

Miku has short red hair with a pink star brooch on her head, and she has magenta eyes. She is usually seen wearing an orange cardigan with a white collar and a red bow attached to it. Her pleated skirt is dark magenta with light magenta trim. Her white socks are knee length and her shoes are magenta

Personality
Miku is a friendly girl who loves her older sister, Akira, with all of her heart, to the point that she will do anything to make a chocolate cake to thank her for looking out for her. Much like Akira, she is very kind and helpful, but sometimes might force herself to achieve something a little bit too much.
