OVA
Description
Maiko Kaneda, a 17-year-old female student, lives in a dormitory near St. Arcadia Academy. She possesses long brown hair extending to her hips, red eyes, fair skin, and a slender yet voluptuous figure with large breasts. Her consistent accessories include glasses worn perpetually—even during bathing or intimacy—and two hair pins. She typically dresses in a white tank top exposing cleavage and nipples, detached sleeves, a black miniskirt, over-the-knee socks, and brown heeled shoes.

Recognized as the most intelligent in her friend group and dubbed "the brains," Maiko frequently reads or uses her computer. Her demeanor presents as quiet, bookish, and occasionally cold-hearted. Despite this reserved exterior, she harbors an exceptionally high sex drive, masturbating "whenever or wherever she can," with group encounters necessary for her satisfaction.

In the prequel, Maiko attends the school’s welcoming ceremony with close friends Saori, Luli, and Yuuki, revealing her bisexuality to them. She later orchestrates a prank against Saori, deceiving her into using a vibrating sex toy under the guise of a medical exam while directing her via radio and masturbating as she watches. Discovering Yuuki and Luli in a group encounter with two male students, she expresses disappointment at her exclusion and immediately joins. During this, she actively pursues the males for gratification, performing oral sex on one while another licks her feet and genitals at her request.

In the main storyline, Maiko is introduced masturbating while reading in the dormitory dining room, drawing the male protagonist’s attention. Later, she provides him intel about the academy’s oppressive control during dinner, her visibly wet panties noted as she departs. She demonstrates computer proficiency, including hacking, and serves as an information source on the school’s controlling forces, showing neither fear nor respect toward the primary antagonist.

Notable events include her participation in a group encounter in episode 3 involving the principal, Orgiwata, Suduu, and two teachers. In another encounter, she exhibits dominance by controlling a female character and multiple males. Her involvement in dormitory baseball activities is also documented.

Maiko maintains close friendships with Saori, Yuuki, and Luli—her best friends—and resides alongside them and Takuro in the dormitory. She navigates proactive yet complex dynamics within this group, evident during collaborative schemes or intimate situations.
