He lives in a moving castle powered by a fire demon named Calcifer. He has an pupil named Michael Fisher.

Howl first meets his love Sophie Hatter on May Day before the Witch of the Waste casts an aging spell on her. He takes her with him to escape the demons that are following him. Days later he gets back to the Castle and is surprised to find an old lady cooking on Calcifer. Despite Michael and Calcifer's complaints he lets Sophie clean the castle. Although he has been gathering clues about Suliman's missing Howl is concerned the King wants him to find Prince Justin. He gets Sophie to pretend to be his mother but the king is more impressed than put off and hires him as the Royal Wizard.

Howl battles with the Witch of the Waste after Mrs Penstemmon's funeral. Now that the Witch knows he lives in Porthaven, he decides to move the castle to escape. Taking Michael and Sophie's wishes into consideration, he takes the hat shop in Market Chipping so Michael stays close to Martha and orders Calcifer to find a nice house with lots of flowers for Sophie. Howl helps in the shop and discovers the dog is a bespelled human. He restores him to his human form and suspects he is made of Wizard Suliman and Prince Justin's body parts. He uses Sophie to get information out of him. As the curse is about to be fulfilled, Howl gets drunk, but he also arranges for Sophie's family to visit. When Sophie falls in the Witch's trap, he raises a wind to bring her back and explains his motives. His honesty seals his fate and the Witch's fire demon, in the shape of Howl's nephew's English teacher, gets hold of Calcifer and squeezes the heart Howl had given Calcifer to keep him alive. Howl collapses but Sophie saves him by giving him his heart back. By breaking Howl's and Calcifer's contract, Sophie returns to her true age. Howl gets rid of the fire demon, restores Suliman and Prince Justin to their true forms and asks Sophie to marry him.

Castle In the air
Howl has married Sophie and she is pregnant with their first child, Morgan. While Howl is casting a locator spell he discovers that a djinn intends to steal the castle from them. He sent Michael and his new apprentice away. He attempts to send Sophie to Wales to stay with his sister Meghan Hatter but Sophie refuses to leave him, asking him to turn her into something so the djinns just won't notice her. When the djinns appear, Howl turns her into a cat in the hope the djinns will think she's just a house cat and leave her be. However, the djinns notice Sophie and toss her out of the castle. Unable to help her, Howl is turned into a Genie and Calcifer into a magic carpet. Howl is cursed so that if he encounters Sophie she will not know it is him and he won't be able to tell her.

Both Howl and Calcifer find themselves in the hands of Abdullah, a carpet merchant, who has also lost his true love to the djinns. Howl promises to grant a wish each day to Abdullah, although Howl uses his powers to cause as much trouble for Abdullah as possible. He later encounters the cat Sophie, who is named Midnight by Abdullah's companion soldier, and she has given birth to Morgan who is a kitten. Although Midnight is unaware of the Genie, he notices her and occasionally suggests he knows Sophie and Morgan. When Morgan is turned back into a baby, the Genie takes him to the moving castle so he can keep an eye on him. Once the djinns are defeated, the Genie is turned back into Howl and he is reunited with Sophie, Morgan and Calcifer. In Castle in the Air, he had two apprentices: Michael Fisher and another unnamed apprentice.
