Tatsu, is a former legendary yakuza gang member known by the nickname "The Immortal Dragon" and he has since retired from a life of crime to work as a full-time house husband for his wife. Tatsu is an intimidating-looking young man with black hair that is usually slicked back, dark-brown eyes, he has facial hair on his upper lip and chin, he has yakuza tattoos that cloaks his entire backside, pectorals and stretch all the way down to his forearms that depict a dragon and he has several scars mark his body, presumably from lacerations due to their shape; one scar on the left side of his face starts at his hairline, dragging down over his eyebrow and ends at his cheek. He is usually seen in a casual-formal wear with a cream-colored Shiba Inu apron on top and he wears aviator shades most of the time, even indoors. Whenever he rides his bike, he is almost always seen wearing a dark fedora and carries a silver metal briefcase.
