Asa and Kame arrive at a palace hoping their new jobs will change their lives. Before they can settle in, they must throw a treasured possession into a well. Kame brings a comb from her grandmother. Her first day at work means giving up something she loves, and she has barely learned anyone’s name.

Mononoke The Movie: The Phantom in the Rain is a Japanese animated horror film about these two new maids. They work inside the Ōoku, the women’s quarters of Edo Castle, where servants answer to senior women who manage the ruler’s household. Asa wants a better job in the household. Kame wants to fit in. Then a dangerous spirit starts hurting people.

The girls give us a reason to care about the haunting. Their friendship makes the palace’s cruelty upsetting before we know what the spirit wants. But following everyone else can be hard. The film introduces names and ranks while cutting quickly between conversations, strange visions and clues.

Asa and Kame need each other

Kame is friendly and eager, but she struggles with her duties and gets picked on. Asa learns faster. When a senior maid berates Kame, Asa takes responsibility to protect her. Asa risks getting in trouble instead of leaving her friend to face it alone.

The friendship starts with small things, including sharing food. Kame’s excitement about palace life is easy to understand: she thinks she has arrived somewhere special. Asa sees opportunities too, but she is more willing to question the rules. They want different things from the same job, but Asa still helps Kame when it would be easier to stay out of trouble.

The well ceremony makes those rules especially uncomfortable. The women must surrender belongings that connect them to home. They also drink water from the well as part of a daily ritual. The film gives us a specific question to worry about: what happens to someone who cannot do everything this place demands? We do not need to know Japanese court history to understand Kame’s fear of being rejected.

Why the Medicine Seller cannot just kill the spirit

The man who investigates the haunting is known as the Medicine Seller. In this world, strong human feelings can combine with a supernatural spirit and create a dangerous being called a mononoke. He carries a sword that can destroy it, but he cannot use it straight away.

The Medicine Seller has to understand the haunting before he can use his sword.

First he must learn what the being is, what happened to create it and which feelings caused it to take shape. These are the film’s “Form,” “Truth” and “Reason.” Finding out how the women have been treated matters as much as finding the monster.

Officials come and go, servants follow different orders, and the film jumps between people before we have much time to remember them. Sometimes the confusion comes from keeping track of the cast, not from a difficult clue. A little more time with those introductions would help.

You can begin here without watching the earlier television anime. Asa and Kame are newcomers too. However, do not expect a full explanation of the Medicine Seller’s background or every part of his powers. This is the first film in a trilogy, not a complete introduction to every detail of the franchise.

The drawings deserve your attention

The palace is covered in painted figures and bright patterns. Even the characters’ faces have a rough, paper-like texture. Background servants sometimes have swirls instead of features, while Asa and Kame have eyes and mouths that show how they feel. The contrast makes the two girls easy to pick out among the workers.

The red, green and purple rooms are beautiful to look at. But during the action, the patterns behind the characters can make their movements hard to see. During faster scenes, there is little time to take in a drawing before the next one arrives. Reading subtitles adds another thing to watch. The film is available with Japanese audio and English subtitles, as well as an English dub; those options may vary by country.

Pixel Twelve verdict

The Phantom in the Rain is worth watching for Asa and Kame. Seeing them help each other makes us want them to get out of danger. We also want to find out why the haunting began, even when the film makes its clues difficult to follow.

But the rushed introductions and crowded action are real problems, particularly for a first-time viewer. Our score is 7.5/10. We recommend it if you enjoy animated horror and are happy to give a film your full attention. If you want a mystery where every clue and character is easy to follow on the first watch, this may frustrate you.

The Phantom in the Rain is on Netflix. See the film page for the trailer and streaming details. The trilogy’s final film arrives on Netflix September 29, 2026; our watch-order guide explains where each film belongs.
