The following contains spoilers For "Demos Slejer: Castle for Infinity".

Anime has a little demon moment. There are several major and popular shows for demons, such as "Jujutsu Kaizen", "Dan Dan" and - of course - "Demon Slejer" (not to mention it Anime-Inspired World Hit What is "KPOP Demon Slayers"). All of these shows show the violence and cruelty of the demons, and also try to give them depth and compassion, usually explaining how they have become as they are and give them relative deficiencies and traits. The problem of humanizing murderous demons is that it is inconvenient to balance them with enough sympathy that audiences care when they are defeated by the heroes, without sympathizing the audience. So Much that forgives more crimes for demons.

This is a big part of the "Demon Sleer", too. Based on the manga of the same name from Kooharu Gothz, the show is followed by Tanjiro Kamado, a young boy who joins the legion of soldiers killing demons, in order to find a way to turn his sister's condition (she was turned into a demon) and retaliates to their dead family.

Tanjiro has an unusual amount of empathy for demons compared to his comrades, walking so far as crying whenever he kills a demon by cutting off his head. Anime is constantly trying to make the audience a little cute towards the monsters that eat man, giving every demon tragic backstew. However, as sad as these stories of origin, they can be isolated, "Demon Slejer" continues to justify, and even link the sad backsters to demons' actions after they start killing people. No matter how tragic life of the character was before turning into a demon; They still became murderous monsters that caused them unbreakable pain.

That is changing to the "demon slaber: a castle for infinity", the first of Three theater feature films that will serve as the end of the story "Demon Slejer". The Infinite Castle gives Acaza (the demon hated by the fans to kill the desired character Ranguku) the most tragic backraging in the franchise yet - a backstew that finds the right balance between sympathy and responsibility.

First we meet with Acase in the "Mugen Train" that serves as The first film and technical second season of "Dem Demjer". Acase is one of the twelve Kizuki, the highest -ranked demons serving the demonic King Muzan. He kills hazering Kiooro Renguku, one of the strongest members of the Corps Demo Slayer and escaped in front of Tanjiro to take revenge.

In "Infinite Castle", we get a rematch between Tanjiro and Acaza. It is an exciting struggle, with spectacular animation and very power and reveals that it pays a story that began in 2020. Then, we find out the story of Acase, returning to several centuries when he grew up as a poor boy forced a crime to finance his father's drug. Unfortunately, after being caught stealing, Acaza's father committed suicide to escape. More bitter, angry and very prone to violence, Acase eventually found inner peace after joining Dogo in military skills and being inbes in Sensei's daughter. But the tragedy hit once again when members of rival dojo killed Sensei and her daughter while Acaza was far away.

Acase, who hated life from a little boy and did not think he deserved to live, decided to accept his hatred and become a demon so that no one could hurt him. It is difficult not to sympathize with him and to understand why he would be so determined to turn the people he thought was strong in demons. But the retrospective at no time justifies hundreds of people slaughtered Acase. During the struggle, Acase sees visions of the spirits of his loved ones, and they are all disappointed with what he has become and what he has done. This is what makes Acase's best story in "Demon Sleerer" and the one who fulfills the promise of the franchise to make demons cute.
