Description
Kazuya Watari is the central male protagonist of the series. He begins as an ordinary high school student whose life is thrown into chaos after he accidentally discovers the secret identity of Hina, a Guardian Heart sent to protect Earth. To preserve Hina's secrecy, he has no choice but to allow her to live with him, a situation his mother readily agrees to despite his strenuous objections. This event sets a pattern for Kazuya's life, as every subsequent girl whose supernatural identity or secret he uncovers also ends up residing in his home.
His personality is marked by a kind-hearted and easygoing nature, often displaying a willingness to help his friends and the girls who come to live with him. Although thrust into bizarre and otherworldly situations, he maintains a relatively grounded and dense demeanor, frequently remaining oblivious to the romantic advances and intense feelings of the female characters surrounding him. This obliviousness, combined with his role as the secret-keeper for multiple magical beings, makes him the calm, if sometimes overwhelmed, center of a chaotic and crowded household.
Kazuya's primary role in the story is to serve as the anchor for the various female leads, each with unique origins and motivations. These include Hina, the fiercely territorial protector; a runaway magical princess who declares him her destined husband; a stoic ninja fugitive named Maya who, bound by clan honor, must become his wife after he saves her life; and an alien mimic who cosplays to use her powers. His motivations are not driven by grand ambition but by a need to manage the escalating supernatural crises and the intense jealousy and rivalry that fracture the group. He is often placed in the position of a mediator, trying to balance the competing hearts and secrets under his roof. Over time, through shared trials and conflicts, the initial hostility from some of the girls, like the ninja Maya, transforms into fragile trust and simmering romance, and he begins to develop a deeper awareness of the romantic tensions surrounding him.
His key relationships are defined by these cohabitation pacts. His bond with Hina is particularly significant, as she loves him and works to keep other girls away, all while hiding her dual life as a Guardian Heart. Other important relationships include Maya, whose icy demeanor thaws into reluctant admiration and a belief that they are fated to be together, and the princess, who is obsessed with him and constantly daydreams about their future. Kazuya's mother also plays a crucial supporting role, as her willingness to let the girls live with him often overrules his own protests.
In terms of his development, Kazuya grows from a normal student into someone reluctantly accustomed to living with supernatural beings. While he is often the target of romantic competition and magical mishaps, he also demonstrates reliability and kindness, which gradually endears him to the women in his life. Regarding notable abilities, Kazuya himself does not possess any innate supernatural powers. However, from time to time, a mysterious entity observes the chaos around him and gifts him transformative heroic powers, allowing him to actively participate in the conflicts that arise within his own home.
