Movie
Description
Mikio Yatsuse is the father of Hiiragi Yatsuse, the protagonist of the story. He is a supporting character who represents the rigid and structured adult world that Hiiragi struggles to navigate. He is a hardworking man with an unshakable belief in his own sense of rightness, and he pursues everything according to that conviction. This trait often makes him insensitive to the feelings of others, particularly his son. His focus on societal expectations and professional stability has created a palpable emotional distance between him and Hiiragi.

In terms of personality, Mikio is characterized by a lack of open communication and a tendency to rely on unspoken expectations. He is a distant figure of authority who is largely unaware of his son's internal struggles. His approach to parenting inadvertently pressures Hiiragi into becoming a people-pleaser who suppresses his own desires. Rather than being actively malicious, Mikio's actions stem from a genuine but misguided wish for his son to succeed. He pushes for private tuition instead of a summer camp, believing he knows what is best. He is also a paranoid and anxious parent who cannot sit still when he thinks his son might be in danger.

Mikio's primary motivation is his concern for Hiiragi's well-being, even if he expresses it through control rather than warmth. He wants his son to excel and follows him during the journey to ensure he is safe. His role in the story is that of a grounded, human contrast to the supernatural chaos introduced by the oni girl Tsumugi. His presence highlights themes of domestic tension and the difficulty of expressing true feelings within a traditional Japanese household. He serves as a catalyst for Hiiragi's rebellion and eventual journey toward self-discovery.

The key relationship in Mikio's life is with his son, Hiiragi. It is strained and formal, defined by unspoken expectations and a lack of emotional warmth. Their dynamic is one of awkward silences and a lack of meaningful communication. Mikio is also the husband of Kaede Yatsuse, though the family dynamic is defined by a quiet adherence to routine over genuine connection. His interaction with Tsumugi is limited, but her presence acts as a disruptive force that challenges his orderly lifestyle and forces him to acknowledge the hidden unhappiness in his home.

The most significant moment of development for Mikio occurs when he catches up to Hiiragi just as his son is swept up by a snow god. He watches helplessly, unable to intervene. This moment forces him to confront the reality of his failing relationship with his son. By the end of the film, there is a subtle shift toward reconciliation. He begins to see Hiiragi as an individual rather than just a reflection of his own parenting. Hiiragi returns home and reconciles with his family, suggesting that Mikio makes an effort to bridge the emotional gap between them.

Mikio does not possess any supernatural abilities. He is an ordinary human who relies on his sense of duty and parental instinct. His notable trait is his unwavering conviction in his own rightness, which defines his actions and his limitations as a father.
