Kanami Shiomiya, a third-year high school student with a slender frame, stands at 163 cm and weighs 43 kg, her physique accentuated by measurements of 83-58-84. Her brown hair cascades into a shoulder-length ponytail, framing blue eyes that contrast her pale complexion. An Aquarius with AB blood type, she finds solace in stargazing and surprises peers with her karaoke prowess.

Raised by her mother following her father’s early passing, Kanami shares a bond with childhood friend Yuuichi, their relationship strained when Kotaro—formerly linked to Yoko—began pursuing her. This entanglement sparked Yuuichi’s jealousy and Kanami’s own unease over the perceived unfairness to Yoko.

Active in a school sports club, her tennis-inspired attire hints at athletic dedication. Her story unfolds within a tight-knit circle of friends, including Mizuki, Youkou, Nagisa, and Karami, all students at Asa Mizushima’s institution. Kanami’s interactions with this group anchor her narrative, weaving a tapestry of camaraderie and interpersonal nuance.
