A junior year student at Kiwiigami High School, student council president, and deuteragonist. Hard-working, stern, kind-hearted, cheerful, forgiving, and compassionate, she holds the traits of a true student council president and offering forgiveness to those that don't even deserve it. It doesn't stop her from taking action, however, as she's known to set rules for students to abide by and taking action immediately. She's also very patient and tough. Despite her outlooks, she's still a normal girl by the end of the day and can be overpowered easily (in the case of Raiko Naeki). Unaware that her family genealogy are the protectors and watchers of R'lyeh, who guards the earth from the rise of Cthulhu, she becomes a sole target for human sacrifice and to break the genealogy and release Cthulhu. Yua already has problems keeping Yaso in check, but lets him off the hook a few times since he's working hard, understands him, and acting out as a housewife for him. Thus, it's the reason why she feels safer when she's near him. Plus, she doesn't see any of the volunteered students a bad seed to society and are just misunderstood, while others she lays down her foot hard and makes sure that they are reported and due to extra work. After being saved by Yaso a few times during the night of the attack of cosmic horrors including the ultimate sacrifice by her once beloved teacher Kate Bushtail, the two began dating one another, showing that their bond that just forged increased drastically and successfully. She continues to be sweet, strong, kind-hearted, compassionate, forgiving, and tough as nails.
Powers:
Genealogical Barrier: As a living generation, Yua's powers are to protect the world from Cthulhu and keep him binded by the Chains of Knowledge, buried deep within the sunken city of R'lyeh. The seal was no longer needed thanks to the intervention of Yaso Inaba, known as the Boy Who Once Cried Wolf, who immediately stops the sacrifice and end the generational barrier, as it is no longer needed due to Cthulhu forever imprisoned within R'lyeh.
