OVA
Description
Kotomi Tsuda affectionately calls her older brother Takatoshi "Taka-nii." She first appears as a junior high student before enrolling at Ousai Academy, choosing it for its proximity to home and following her brother's path. Teacher Naruko Yokoshima facilitated her admission, recognizing Kotomi as a kindred spirit during the entrance interview, which contributed to her acceptance despite academic challenges.
Physically, Kotomi possesses long dark brown hair typically styled in twintails, brown eyes, and a frequently smiling or grinning expression. She exhibits a more fashionable sense of style than Takatoshi, often seen in varied casual outfits. After starting high school, her physical development is noted, particularly her breasts, which outgrow her initial uniform, causing discomfort and surpassing Shino Amakusa's bust size—a point of irritation for Shino.
Her personality is characterized by cheerfulness, approachability, and an aptitude for making friends across different grades, including seniors like Mutsumi Mitsuba. Her natural charm leads others, such as Suzu Hagimura, to suggest she could be an idol. However, she struggles academically due to laziness and a lack of motivation, requiring extensive tutoring from Takatoshi or Suzu to meet school standards. She displays childlike tendencies, including vivid imaginations where she casts herself as a shōnen anime protagonist.
A defining trait is her unabashed interest in adult themes, particularly unconventional sexual topics. She is well-versed in pornography and dating simulation games (galge), often discussing explicit matters openly and inappropriately, regardless of setting or company. This places her among the most overtly perverted characters, alongside Shino, Aria Shichijō, and Yokoshima-sensei. Her airheadedness and penchant for jokes blur the line between humor and sincerity, especially regarding incest-themed remarks about Takatoshi. While she frequently teases about romantic or physical involvement with him, no concrete evidence supports genuine incestuous feelings; these are attributed to her provocative humor and lack of situational awareness.
Her relationships reflect her sociable yet eccentric nature. She shares a close, trusting bond with Takatoshi, relying on him heavily—especially when their parents are away—and often assisting with household tasks. Her friendship with Toki, her first high school friend, defies Toki's delinquent appearance, as Kotomi sees her true clumsy and non-confrontational nature. With Shino and Aria, Kotomi engages freely in perverse banter, leveraging Shino's tolerance and Aria's similar interests. She respects Suzu as a capable upperclassman but also subjects her to teasing, with Suzu occasionally acting as a straight man to her jokes. Kotomi also subtly perceives romantic tensions, such as Shino's feelings for Takatoshi, though her awareness of Suzu's feelings is less clear.
Her development includes transitioning from junior high to Ousai Academy, where her social circle expands. While her core traits remain consistent, minor growth is implied through physical maturation and occasional moments of perceptiveness—such as recognizing others' emotions—though these are often overshadowed by her comedic role. A notable moment occurs in an OVA wedding-themed segment, where she appears alongside potential brides for Takatoshi, highlighting the recurring ambiguity around her jokes about their relationship.
Her name's kanji means "harbor/port" and "paddy field." Her larger bust size compared to Shino is noted, and she shares thematic elements common to the author's other works, such as sisters with crushes on brothers—though Kotomi's case is treated humorously rather than seriously.
