Description
Kokoro "Shii" Kōki attends Yuyuyou Girls' Vocational High School alongside Miku "Purin" Suride, thriving within its elite technology-focused curriculum. Raised on a sprawling Southeast Asian estate under wealth and privilege, she shares a lifelong bond with childhood companion Haruko Hoketsu. Her Japanese name—Kokoro ("heart/mind") paired with the surname Kōki ("fortune/hope")—hints at her inquisitive spirit, while the nickname "Shii" stems from the trailing kanji in *koukishin* ("curiosity"), mirroring her relentless thirst for discovery.

Energetic and acrobatic, she moves with feline grace, peppering speech with playful "nya" suffixes. Her agility borders on supernatural, scaling walls, slipping through windows, or perching atop rooftops with kunoichi-like stealth. She wields surprising physical strength, single-handedly constructing treehouse frameworks, while her academic prowess shines in high-tech realms—hacking school security to access restricted labs or mastering 3D printing systems.

A longtime admirer of Gatagata Girls' High School’s DIY Club, she covertly studies their projects from Yuyuyou’s windows. By Episode 5, she joins as an external member, circumventing cross-school enrollment barriers by crafting an unsanctioned uniform mimicking Gatagata’s design. Within the club, she bridges technical expertise and raw labor—engineering intricate accessories via 3D printers or hauling materials—and openly credits the group with deepening her sense of purpose, a revelation she passionately shares with her family.

Her dynamic with the DIY Club highlights adaptability and fervor, merging cutting-edge innovation with hands-on craftsmanship. Despite her affluent upbringing, she integrates seamlessly into the team, channeling her eclectic skills to elevate collaborative ventures without pretense or hesitation.
