Description
Minamo Narukaze is a teenage girl with distinctive violet hair styled in twin tails, featuring an ahoge, straight long strands, and side hair, complemented by green eyes. She stands 158 cm tall, weighs 46 kg, and has bust-waist-hip measurements of 82-58-85 cm, presenting a pale, slim figure. Her attire frequently includes a school uniform, maid's dress, yukata, one-piece swimsuit, Mary Jane shoes, ribbon ties, and ribbons for her hair or body.

Born on July 21 in Kazune City, Minamo formed a deep childhood bond with Makoto Okano and his younger sister Hinata. After the death of Makoto's father, both families relocated separately. During their second move, Makoto gave her a harmonica, and they sealed a pinky promise to reunite and marry. Minamo kept the harmonica, practicing it for four years while holding their promise as a sincere vow.

Her personality blends kindness, honesty, and emotional openness with occasional clumsiness, especially in cooking, which she continues despite limited skill. She exhibits deredere traits—open affection—alongside a serious, friendly nature. Generally reserved and shy, she becomes assertive and straightforward about her romantic feelings for Makoto.

Ten years after their separation, Minamo reunites with Makoto and Hinata upon their return to Kazune City. Now an eleventh-grade high school student and Makoto's classmate, her family background reveals she is the biological daughter of Professor Akihito Narukaze and the full sister of both Hinata and Wakaba Fujimiya, though they were separated and raised in different households.

Minamo possesses the supernatural ability to control wind, a common trait among Kazune residents. Her activities involve playing volleyball, shopping, and assisting her father's investigations into the town's mysteries, which include murders and disappearances linked to the origins of these powers.

Throughout her story, she actively pursues a romantic relationship with Makoto, emphasizing their childhood promise and her desire to marry him. Her involvement in uncovering Kazune's secrets alongside her father and friends is central to her narrative. Her familial bonds, particularly with Hinata and Wakaba, are reaffirmed, solidifying their sisterly connection despite their separation.
