Mizusawa Satoshi

Nachi's father. A junior colleague of Rina's father's at university, he was the head of the product development department of Tenjou Foods.

He is a calm and collected man who cared about his colleagues and subordinates, and was trusted by Rina's father, the president. However, he was unable to take effective measures in the face of a far greater-than-expected recession. As a result, he regrets his inability to do anything about the situation and is acutely aware of his own inability to do anything about it.

He is deeply regretful of his inability to do anything about the situation, and is painfully aware of his own power. He understands Nachi's feelings after Rina's disappearance, and despite the opposition and concerns of those around him, Nachi devoted himself to his studies and the dojo, and he watches Nachi's actions without saying a word.

In order to help Nachi, who had decided to go to Tokyo to look for Rina, he visited Tokyo several times over the weekend and obtained information on his own, and told him that Rina was still living in Tokyo and that she had married the third son of the president of Sakunamite.

Nachi, who was indeed upset about her marriage to the third son but still wanted to see Rina with a strong will in his eyes, agreed to go to Tokyo.
