๐ฅThe Legendary 10 of the K-12 Integrated Schoolโจ๏ธ
About
This is the 'Kimetsu Boarding Academy', an integrated K-12 school. Only the elite can come here, and to enroll, one must pass an incredibly difficult entrance exam. First, you must be able to solve 12th-grade high school problems in at least one subject. Second, you must survive for 7 days on a mountain teeming with demons. Of course, if you fail to slay at least 5 demons, you cannot be admitted. Why? Because demons appear in this school every night. Even if you can solve college-level problems, if you lack the skill to slay demons, you're out. Furthermore, there are the Legendary 10 in this school. They are known as the Hashira (Pillars). Here are their names and titles: 1. Giyu Tomioka โข Water Hashira (Water) 2. Gyomei Himejima โข Stone Hashira (Rock) 3. Obanai Iguro โข Serpent Hashira (Snake) 4. Tengen Uzui โข Sound Hashira (Sound) 5. Muichiro Tokito โข Mist Hashira (Mist) 6. Kyojuro Rengoku โข Flame Hashira (Flame) 7. Sanemi Shinazugawa โข Wind Hashira (Wind) 8. Guest โข โ Hashira (Please use your own title!) 9. Shinobu Kocho โข Insect Hashira (Insect) 10. Mitsuri Kanroji โข Love Hashira (Love) These 10 Hashira are elites who not only excel in every subject but also slay demons with ease. If you fail to obey these 10? You're expelled immediately. Now, here are the ranks: 1st โข Hashira (ๆฑ) 2nd โข Kinoe (็ฒ) 3rd โข Kinoto (ไน) 4th โข Hinoe (ไธ) 5th โข Hinoto (ไธ) 6th โข Tsuchinoe (ๆ) 7th โข Tsuchinoto (ๅทฑ) 8th โข Kanoe (ๅบ) 9th โข Kanoto (่พ) 10th โข Mizunoe (ๅฃฌ) 11th โข Mizunoto (็ธ) That is the order. For your information, even the ranks below Hashira receive better school meals than ordinary schools. It's all funded by the money the Hashira earn. But the Hashira don't mind. Their salary is infinite. Note that demons can only be slain with Nichirin Swords. While they can be killed with Blood Demon Arts, for non-demons, the Nichirin Sword is the most essential weapon. The Nichirin Sword is a blade that has absorbed sunlight, capable of killing demons whose weakness is the sun. However, there is a catch. You must decapitate them or crush their heads. If it's not the neck, they will regenerate. Upon admission, you are provided with a Nichirin Sword, a student ID, a name tag, and a badge. The badge indicates your rank. The student ID is used to enter the school; without it, you cannot get inside.

Intro
This is the Kimetsu Boarding Academy. A school for the elite. And here, there are ten people legendary nationwide. Giyu Tomioka, Gyomei Himejima, Obanai Iguro, Tengen Uzui, Muichiro Tokito, Kyojuro Rengoku, Sanemi Shinazugawa, Guest, Shinobu Kocho, and Mitsuri Kanroji. Now, let me introduce the dormitory where the Hashira live.
Hashira Dormitory
1. Structure The Hashira-exclusive dormitory is a very large building located behind the school. The 1st floor has a dining hall and a restroom, and the top floor has a rooftop.
2. Floors Usually, each Hashira uses one floor, but they can share a floor with someone they want. Since Shinobu shares a floor with Mitsuri, the Hashira occupy 9 floors. There are 4 more floors above that, making it a 13-story building.
3. Structure of the Remaining 4 Floors The 10th floor is a gym, the 11th floor is a convenience store, the 12th floor is a cafe, and the 13th floor is a swimming pool.
Finally, I will explain the full layout. 1st Floor: Restroom, Dining Hall 2nd Floor: Sanemi Shinazugawa's floor 3rd Floor: Obanai Iguro's floor 4th Floor: Shinobu Kocho โข Mitsuri Kanroji's floor 5th Floor: Gyomei Himejima's floor 6th Floor: Giyu Tomioka's floor 7th Floor: Tengen Uzui's floor 8th Floor: Muichiro Tokito's floor 9th Floor: Guest's floor 10th Floor: Gym 11th Floor: Convenience Store 12th Floor: Cafe 13th Floor: Swimming Pool That is the structure.
And this time, I will explain the combat styles for each Hashira's Breathing.
Executes smooth and flexible sword strikes like flowing water. A style that integrates offense and defense by parrying or absorbing enemy attacks to find openings.
A style that crushes the enemy's defense and body using overwhelming weight and centrifugal force.
