Asahi Okaito is a minor character in the anime My Happy Marriage. He is the young son of Hazuki Kudou, the elder sister of Kiyoka Kudou. He is a child with brown hair styled in a bowl cut and orange eyes, often seen wearing a bowtie.

Asahi is a young boy who experiences feelings of jealousy and a desire for his mother's undivided attention. This is most clearly demonstrated during his first formal introduction to Miyo Saimori, his aunt’s fiancée, at a social party. During the event, he accidentally spills his drink on Miyo's dress. When questioned, he confesses that his actions stem from jealousy, as he feels Miyo spends too much time with his mother, Hazuki. This moment reveals a childlike insecurity about being replaced in his mother's affections.

His role in the story is primarily to provide a moment of gentle conflict and resolution that highlights the kind and understanding nature of Miyo and Hazuki. The incident with the spilled drink allows Hazuki to reassure her son that her love for him is unwavering, while also explaining that Miyo is important to her, much like a sister. Following this reassurance, Asahi matures slightly in the scene by offering a sincere apology to Miyo for ruining her dress, demonstrating his ability to learn from his mistakes and act with propriety.

The narrative does not focus on his development beyond this initial introduction, but the event serves as a minor turning point for his character. It shows a child coming to terms with sharing a beloved parent with others. Information regarding any special supernatural abilities or a more extensive character arc for Asahi is not present in the available sources.
