Daimon is the fourth and last son of the Tatsumi family. Daimon is a Sergeant at the Capital Police Department. He is the hot head of the group, who rushes into things before thinking and getting into trouble. Anguished at his brother, Nagare, for being put on suspension for something that was not his fault, Daimon sticks up for him. Daimon is somewhat the joker of the team, being the youngest male he can be pretty reckless and cocky. Daimon had to learn to be a team player, one of the reasons why he is always yelled at by Matoi is because he thinks he can handle any situation on his own without his sibling's help. Matoi tells him that they are all a team to win a fight they have to work together, he cannot let his pride get in the way of saving the world. Then when the team works together they are far greater and more powerful then working alone. A lesson that Daimon learns the hard way. He can be somewhat indulgent. Although he might rush into a fight he can still be reliable in an emergency. He has an obsession with drinking milk. A wannabe bike cop, he is the only sibling not in the Fire Department. When Pierre returned and began terrorizing the city, Domon and his family came out of retirement and helped the Timerangers defeat the Saima demon. In Gaoranger vs. Super Sentai, Daimon taught Kai Samezu how to perform his famous "Banba-Style Cow's Killer Milk Tornado Drop" , which Samezu eventually uses on Lost Highness Rakushaasa.
