人生のメリーゴーランド _ハウルの動く城 Howl's moving Castle

Howl's Moving Castle (ハウルの動く城 Hauru no Ugoku Shiro?) is a 2004 Japanese animated fantasy drama film written and directed by Hayao Miyazaki of Studio Ghibli and based on the novel of the same name by Diana Wynne Jones

The film is very different from Jones's original novel. The plot is similar, but it is flavored with Miyazaki's familiar style and characters, as well as several missing or drastically altered key plot points from the book. The plot is still focused on Sophie and her adventure while cursed with old age; however, the main action of the film's story takes place during a war, and its plot is chiefly concerned with Howl's attempts to avoid fighting in it for pacifist reasons. This aspect of the film's plot is actually rooted in Miyazaki's political views as a pacifist

Plot
Sophie, a hatter, is a responsible-yet-plain 18-year-old girl who on her way to the bakery to visit her sister encounters by chance a mysterious wizard. This encounter arouses the Witch of the Waste, who comes to the hat shop and curses Sophie, transforming her into an old woman. As the curse prevents her from telling anyone of her condition, Sophie decides to leave and seek out a cure.
Sophie meets the fire demon Calcifer, who powers the castle and recognizes that Sophie has been cursed. Calcifer offers to break the curse in exchange for Sophie's help in breaking the spell he's under, which keeps Calcifer bound to the house. When Howl appears, Sophie announces that she is the castle's new cleaning lady, hired by Calcifer because he was sick of how dirty the castle was.
Currently, the country Sophie is in is caught up in the beginning of a war with its neighbor following the mysterious disappearance of the other realm's Crown Prince, and slowly the war begins to creep into Sophie's country itself. Howl receives summons from the King, who orders his various assumed identities to fight in the war. However, Howl comes up with an idea to send Sophie, as his mother to announce what a coward he is and that he would be useless. At the palace, Sophie runs into an asthmatic dog, Heen, who she thinks is Howl undercover. She also meets the Witch of the Waste, who Suliman punishes by draining all of her power, causing her to regress into a harmless old woman, with little memories of her past actions. Suliman tells Sophie that Howl will meet the same fate if he does not contribute to the war. As Sophie vehemently protests these measures, the Witch's spell temporarily weakens due to the love in her words. Suliman realizes Sophie's true relation to Howl and her feelings towards him. Howl then arrives to rescue Sophie, Suliman tries to entrap Howl, but with Sophie's help, they manage to escape.
Sophie learns that Howl transforms into a bird-like creature to interfere in the war, but each transformation makes it more difficult for him to return to human form. Sophie fears that Howl is preparing to leave them, as his remaining time as a human is limited, he returns to interfering in the war. Sophie's mother shows up and is actually under Suliman's control and leaves behind a bag containing a "peeping bug" under her orders. The former Witch of the Waste discovers it and promptly destroys the bug by tossing it into Calcifer. Unfortunately, Calcifer gets sick after eating the bug, rendering him unable to protect the castle from being discovered.
A few hours later, the city is carpet-bombed by enemy aircraft while Suliman's henchmen invade the hat shop. After arriving in the nick of time and protecting the hat shop from the bombing, Howl draws the guards away just after healing Calcifer. He tells Sophie he is not going to run away anymore because he has something he wants to protect before leaving to interfere with the war. Deducing that Howl must be saved, Sophie moves everyone out of the castle and removes Calcifer from the fireplace, destroying the castle. She offers Calcifer a piece of her hair to give him strength enough to power a portion of the castle. They head toward Howl when the former Witch of the Waste discovers Howl's heart within Calcifer. Sophie pours water on Calcifer to make her let go of the heart, making Calcifer lose his power. The segment of the castle is split, and she and Heen fall down a chasm.
Making her way toward Howl's heart, Sophie enters through the door into the black region, Howl's childhood. She sees a recollection of how Howl and Calcifer meet: Howl eats Calcifer, who then gains his heart. Sophie finds Howl, having now lost his human consciousness in bird form. They head back to the group, and Sophie asks the Witch for Howl's heart. She gives it to her and places the heart back in Howl, resurrecting him and freeing Calcifer. She kisses the scarecrow who reveals that he is actually the missing prince. Heen shows the scene of their happy end to Suliman, and the war is finally over. Howl, Sophie, and the others are seen high above the bomber planes returning home from the end of the war.
