Father Michishio

満潮の父

Nagasumi's father is always shown as an object of suffering, due to his wife's dying love for Masa. Whenever his wife shows her interest in Masa, he is shown in a depressed state, like the time she offers Masa her home cooked meal, he is shown coughing on a burger and then subsequently harangued by his boss to get back to work.
