Sleepy Princess in the Demon Castle is a hugely popular manga currently being serialized in Weekly Shonen Sunday. Its charm lies in its adorable characters and unconventional fantasy development. The novel story of a captive princess trying to get a good night's sleep in a castle using every trick in the book has been a hot topic, and it has been decided that the series will be made into a TV anime in October 2020. But what kind of characters appear in Sleepy Princess in the Demon Castle? In this article, we will take a closer look at the unique characters that appear in Sleepy Princess in the Demon Castle.

Character 1: Aurora Suya Reese Kaimin (Princess Syalis)

Princess Syalis

First, let me introduce the main character, "Aurora Suya Reese Kaimin". Although her name is quite long, people often call her "Princess Syalis" and monsters often call her "Princess". She is the princess of the Kaimin country, a unified nation of humanity. She inherited everything except for her name "Suya", and the stars in her eyes are a sign of royalty. This story begins when Princess Syalis is kidnapped by the Demon King and imprisoned in a castle. Although she has a quiet personality, she is actually quite sharp-tongued and does things at her own pace. Furthermore, she has incredible drive, and even after being imprisoned in the castle, she continues to manipulate the demons. When she gets serious, she has a scary side.

Her fighting ability is quite impressive! ?

Princess Suyaris

Contrary to her cute appearance, Princess Suyaris has considerable fighting ability. However, unlike demons, she is a flesh-and-blood human, so she cannot deal with abnormal conditions or traps, and she dies frequently (!) and has to be revived by the "Demon Army" each time. By the way, the princess is also very dexterous, and she makes everything herself, including the things around her and large furniture. Although he is imprisoned in the castle, he has no problems with food, clothing, and shelter, and most importantly, he has nothing to do but sleep, so he spends his time doing whatever he likes, as if he will do anything to get a good night's sleep.

Character 2: Demon King Tasogare

Demon King

Demon King Tasogare is, as his name suggests, the demon king, the master of the Demon King's castle, and the person who kidnapped Princess Suyaris. In this world, power is divided between humans and demons, and he is trying to take over that position entirely. By the way, this work "Sleepy Princess in the Demon Castle" contains role-playing game elements, and the Demon King Tasogare carefully balances battles, manages flags, and adjusts game balance to prevent the hero Akatsuki from reaching him easily.

What kind of character is he?

Even though he is a demon king, he usually looks like a young human. However, when he gets serious in a battle, his appearance changes. As a demon king, he has considerable power, but he has a slightly weak personality. By the way, he feels guilty about kidnapping Princess Suyaris and is considerate of her, but he is often at the mercy of the free-spirited princess. He loves the previous demon king (his father) too much, so he has a daddy's girl side.

Character 3: The Devil's Church

The Devil's Church

The Devil's Church is a demon and the boss of the Devil's Church. He looks like a gentle young man with a soft demeanor, but he is actually quite old and is often called an "old man." He is also in charge of reviving people in the castle, such as Princess Suyaris. The Devil's Church also worships the evil god, and is very busy at Christmas, when they hold a dark mass. (But it's just a normal Christmas party.)

A pretty pitiful position

The demon army is in a pretty inconvenient position, just like the Demon King. Since Princess Suyaris arrived at the castle, the monsters he's been manipulating have been dying one after another, and he's been busy reviving them. At first, he thought of the troublesome princess as a granddaughter, but people around him have pointed out that his feelings have gradually turned to love, and it seems he can no longer hide his feelings. By the way, his real name is Leonard. The princess calls him "Leo-kun."

Character #4: Red Siberian Kai

改

Red Siberian Kai is a demon of the Demon Beast tribe. He is a close aide to the Demon King. He regulates the morals within the castle with the "Demon King Castle Code" and has a personality that values discipline. He also has many "Red Siberians" under his command. His favorite food is meat. He is characterized by his fluffy chest hair. He fights in groups, but when attacking alone, he uses his claws, sabbats, and fangs. He tries to lecture Princess Suyaris every time she does something wrong, but it doesn't go well because the princess uses her chest hair as a blanket and falls asleep while he lectures her. He once tried to cut her chest hair, but the Demon King likes it, so he can't cut it.

Character 5 Neo Alraune

Neo

Neo Alraune is a plant-type monster and a woman. She is the boss of the plant area "Secret Garden". She has a kind personality, and at first she sympathized with Princess Suyaris, but after seeing her behavior, she seems to have changed her mind. By the way, she has an excellent figure, and flowers bloom from her head and hair. The princess calls her "sexy".

Character #6: Kaendokuryu

Kaen

Kaendokuryu is the boss of the fire area "Ancient Volcano" and is half dragon and half demon (though he doesn't look like a dragon). He covers his face with a shield to protect himself from poison. He is also quite unlucky and has a vindictive personality.

Character No. 7: Hades

Hades

Hades is a demon relative. He is one of the "Ten Masters" who has considerable power, but he does not acknowledge the Demon King Tasogare, so he has left the current Demon Castle and is calling himself the master of the old Demon Castle. His weapon is a giant scythe. He calls Tasogare a "youngster" and at first glance seems to be in conflict, but deep down he does not seem to hate him that much. He also kidnapped Princess Suyaris from the Demon Castle and provoked Tasogare, but Hades himself was at the mercy of the princess who was too free.

Character #8: Poseidon

Poseidon

Poseidon is the boss of the deep sea area "Forgotten Deep Sea" and is a monster of the divine tribe. He is the god of the sea and the younger brother of Hades. Although his status is quite high, he is currently under the command of the Demon King. He looks and feels young, and as the god of the sea, he has a water attribute. By the way, on Marine Day, he gathers faith from humans and can transform into an adult.

Character #9: m.o.t.h.e.r

m.o.t.h.e.r is the boss of the "Karakuri Area". He has a worrisome and secretive personality. He withdraws into the "Perfect Paradise (Alpha Paranoia)" in the Karakuri Area, where he has created many Karakuri tribes. He found his body, born as a chimera, inconvenient, so he modified it several times to become what it is today. When he saw Princess Suyaris, he created the Weapon Princess Robot Mark III.

Character #10: Debiakuma

Debiakuma

Debiakuma is a mascot character that is loved as a pet. It is a low-ranking demon among the demon tribe. Princess Suyaris has tamed him as a pet. Brushing it will give you good cotton, so the princess often brushes it for you. At this time, the Devil Bear became addicted to brushing and offered the key to the cell in exchange. Since then, even if the princess loses her key, she can get it back by brushing the Devil Bear... and so on. As a low-ranking monster, its combat ability is extremely low, and when it comes to fighting, it either runs away or calls its allies (occasionally the princess is called).
