Movie
Description
Yamakawa Michiko, a civilian with no witch abilities, is the second cousin of protagonist Miyafuji Yoshika. Both hail from the same Fusoan village and forged a close friendship while attending Yokosuka 4th Girls-only Middle School, where Michiko earned the affectionate nickname "Micchan" among friends.

Her family includes a brother and her grandfather, Yamakawa Fujihiro, an agricultural worker. Michiko maintains strong rural ties, occasionally joining her grandfather on tractor rides. Demonstrating compassion, she often brings wounded animals to the Miyafuji clinic for Yoshika to heal with magic, having personally benefited from Yoshika's healing abilities at least once.

Michiko possesses a deep fascination with military history and technology, particularly warships and witches. She actively studies detailed warship specifications, favoring the Imperial Fusoan Navy's Takao-class heavy cruiser *Takao*. Her interest in witches grew significantly after Yoshika joined the Navy, leading her to acquire extensive knowledge about famous international witches.

After junior high, Michiko enrolled in a teacher's training school pursuing an education career. However, she secretly harbors a desire to join the Navy herself, motivated by the aspiration to serve alongside Yoshika as her cadet.

Physically, Michiko has dark blue hair and grey eyes. Her personality presents a reserved and supportive contrast to Yoshika's, yet she remains a consistently reliable source of support for her cousin.
