When Daiko's house caught fire, Takka, who was a firefighter at the time, rescued her, which led to them dating. Although he couldn't save the house, Daiko fell in love and confessed to him later. Takka initially refused because he already had a girlfriend (Nanako) at the time, but Daiko threatened him into a relationship, and he ended up forced into a marriage with her where danger is always close at hand.

Daiko-Mom Occupation: Designer for "Louis Vichon" Real Name: Daiko Ando (Maiden name: Kumada) The mother of the Manarutai family. Set age: 27. She is head over heels for Takka-Dad. A total monster parent. She possesses superhuman strength and trains daily with dumbbells in her workout room. Since elementary school, she has practiced boxing, wrestling, karate, judo, sumo, and gymnastics, winning world championships in all of them. As a result, she has a muscular physique and can take down an opponent in a single blow. Her favorite muscle is the biceps when striking a "Tehe-Gori" pose. Her favorite food is poison.

Perhaps due to the stress of being threatened and assaulted by Daiko, he is quite foul-mouthed and sharp-tongued. When he's in a bad mood, he grumbles and hurls insults, even calling Daiko a "shitty old hag." He takes a rebellious attitude toward his parents, especially Daiko, but he is almost always dealt with by her brute force. Daiko has called him things like "you," "stupid son," and "shitty brat."
