Miku's Father is the unnamed husband of Miku's Mother and father of Miku Kuroda. He has a stout build, thick brows, prominent sideburns, and a mustache. Initially fearful of his son-in-law Tatsu due to Tatsu's intimidating yakuza background and fearsome reputation, he nonetheless persistently tries to build a familial relationship with Tatsu. He actively seeks father-son activities like playing catch, reflecting his underlying care for his daughter's well-being and desire to foster a positive marriage despite his stern exterior.

He shares a distinct, aggressive, and chaotic cooking style with his daughter Miku, characterized as "knife 'Hacking' skills" and messiness, explicitly demonstrated during hotpot preparation. This culinary approach is established as a familial trait passed from father to daughter.

His character development focuses on his changing relationship with Tatsu. His initial wariness lessens as he witnesses Tatsu's commitment to domestic life and Miku. This leads him to actively pursue a closer bond, making repeated, sometimes awkward, efforts to treat Tatsu as his own son, even while acknowledging Tatsu's lingering intimidating aura.
