Makiko Terakado is a supporting character from the manga and original video animation Nozoki Ana. She is a female college student at an art school, born on July 17 and aged 18 with blood type A. She has auburn hair that she typically wears up and brown eyes. Makiko is part of the same friend circle as Tatsuhiko Kido, Yoneyama, and Emiru Ikuno, having bonded with them after a karaoke event organized by Yoneyama. She is portrayed as a mutual and supportive friend who values her connections within this group. Makiko is intelligent and observant; she actively investigates the nature of the relationship between Tatsuhiko and Emiru by checking the apartment register, thereby deducing that they are neighbors. This leads her to discover the existence of the peephole between their rooms. Her personality is marked by a blend of amiability and perceptiveness, and she is not afraid to involve herself in the personal affairs of those around her. Her motivations are deeply tied to her feelings for Emiru. It is revealed that Makiko is a lesbian or bisexual and harbors romantic love for Emiru. This unrequited affection serves as a central driver for her actions, prompting her to visit Emiru's room and further explore the dynamics at play. Her role in the story is that of a secondary character who provides additional insight into the main pair's secret arrangement and becomes a source of external perspective on their relationship. In the original video animation, her role is more limited compared to the manga, where her backstory and personality are more thoroughly developed. A notable detail from the manga is that she had already known Yuri Kotobiki before becoming closer with the rest of the group, indicating pre-existing social connections within the art school setting. Makiko's key relationships are with Emiru, towards whom she feels romantic affection, and with Tatsuhiko and Yoneyama, whom she considers close friends. Her development primarily revolves around her handling of her feelings for Emiru and her growing awareness of the secret arrangement between Tatsuhiko and Emiru. In terms of abilities, Makiko is characterized by her deductive reasoning and her capacity to gather and piece together information about her peers, demonstrating a sharp and investigative mind. She serves as a figure who is both part of the central social circle and slightly outside its most intimate secrets, giving her a unique vantage point within the narrative.
