Description
Chisa Kotegawa is a first-year student majoring in mechanical engineering at Izu University. She has a petite build, standing at 152 centimeters tall, with short brown hair and brown eyes. Her family owns the Grand Blue diving shop, which serves as the base for the Peek a Boo diving club, and she has been immersed in the world of diving from a very young age. This lifelong exposure has given her a deep passion for the ocean, and her primary motivation is to become a professional diving instructor. She also assists at an aquarium, applying her diving skills in a practical setting.
Chisa is typically level-headed, serious, and rational, often acting as the voice of common sense in contrast to the chaotic behavior of the other club members. She is generally disinterested in fashion, romance, and the drunken parties that frequently occur at Grand Blue, usually choosing to observe from the sidelines. Her aversion to the club's drinking culture stems from an extreme sensitivity to alcohol. Despite her calm demeanor, she has a fierce and expressive side that emerges when she is angered. This is most often triggered by the vulgar antics of her non-blood-related cousin, Iori Kitahara, to which she reacts with sharp, sarcastic insults and terrifying, contemptuous glares that can convey genuine murderous intent.
Chisa and Iori are considered cousins, but they share no blood relation due to a family adoption arrangement. Initially, she viewed Iori with disgust, particularly after their first reunion saw him drunk and half-naked. Over time, however, her feelings evolved as she witnessed his sincere and kind nature, especially after he helped resolve a long-standing misunderstanding with her mother, Sayaka, during a trip to Palau. This misunderstanding had led Chisa to believe her mother disapproved of her career aspirations, but Iori discovered that Sayaka was simply deaf in one ear and had not heard Chisa's request. The resolution of this conflict marked a significant turning point, leading Chisa to become more积极主动 and open with her feelings toward Iori. She later initiates a scheme to have Iori act as her fake boyfriend to deter other suitors, a pretense that becomes complicated as she grows increasingly possessive and jealous, particularly when other women show interest in him. This internal conflict marks her key development, as she struggles to process and accept her emerging romantic feelings.
Chisa also has a close but complicated relationship with her older sister, Nanaka, a diving instructor who harbors an intense, obsessive affection for her that largely goes unnoticed by Chisa. Within the diving club, she is good friends with Aina Yoshiwara, though she remains unaware of Aina's envy regarding her relationship with Iori. Despite her disapproval of the club's rowdy behavior, she shares a strong bond with its members through her love of diving and is often praised for her cuteness by senior member Azusa Hamaoka. Chisa is noted for her stubbornness and physical fitness, possessing the athleticism and strength necessary for demanding underwater activities. She is also one of only three female students in her engineering major, making her a subject of admiration among her male classmates, though she consistently rejects their romantic advances.
