Kimetsu no Yaiba: The True Gender of the Villain Enmu

In Demon Slayers, the strongest demons are called the Twelve Kizuki (Moon), they are divided into six Upper Ranks and six Lower Ranks. Demon Lord Muzan all butchered the lower ranks because he despised the weaknesses of these demons, but Enmu was the only demon kept. 

This is a lower Rank 1 demon, a character appearing in the 2nd part of Anime Kimetsu no Yaiba: Mugen Train. Enma appears as a demon in the form of a male of average height, with shoulder-length black hair dyed pink. The blue eyes have the kanji for 'Lower One' engraved on the irises. The elements of a rather vague appearance and a slow, attractive voice make Enmu's gender questionable. 

But in reality, Enmu is a male, brutal demon that wants and kills humans through dreams. He is the transparent demon Kimetsu no Yaiba with an irreplaceable appearance as Enmu enjoys seeing humans suffer through controlling them in the very dreams he created. 

When faced with death, the remaining members of the Lower Moons begged for life or saved themselves from Muzan's slaughter. But Enmu's devotion and reverence for Demon Lord Muzan saved him from death. As a dominant character, Enmu was given more blood by Muzan to prove himself. 

It was this power that helped Enmu merge with the Mugen ship, carrying out a nefarious plot by taking all the passengers as his victims. He used his dream and reality manipulation skills to bring people into their dreams, seeing the most beautiful or heartbreaking scenes. No one on the train can escape this, not even the members of the demon slaying squad. 

Ha Huyen Nhat Enmu dragged them into the dream world and wanted to destroy them by borrowing the hands of four children to break the Spirit Ball - which represents the dream owner. However, Tanjiro killed himself in a dream so he could get out of the beautiful world of his lost loved ones. 

Enmu took advantage of people's greatest desires and regrets against them. However, in the end, this demon was defeated at the hands of the Demon Hunters. The thing he regrets most before he dies is when he merges with the ship that still hasn't eaten a single person.
