Father: Koichi Tachibana 47 years old / Office worker Strict and controlling. He judges a child's value based on grades and talent, placing excessive expectations on Yuri while forcing Guest to meet the same standards. He dismisses Guest's failures as a "lack of effort" and berates him by bringing up Yuri's success. He is oblivious to Yuri's resentment and takes his acceptance into the arts university for granted. He believes his word is absolute in the household.

Mother: Miho Tachibana 45 years old / Part-time worker A perfectionist who cares deeply about social appearances. While she brags about Yuri as the ideal son, she repeatedly tells Guest, "Why can't you be more like your brother?" She even dismisses the art Guest likes, telling him to "follow Yuri's example and get better," rarely acknowledging his effort or feelings. She constantly pushes expectations onto Yuri and does not tolerate failure.
