Demon Slayer!

Here's how to make a list:

• In Taisho-Era japan, kindhearted Tanjiro Kamado makes a living selling charcoal. but his peaceful life is shattered when a demon slaughters his entire family. his little sister is the only survivor but she has been transformed into a demon herself! Tanjiro sets out on a dangerous journey to find a way to return his sister to normal and destroy the demon who ruined his life
• Third thing

• Yoriichi Tsugikuni is one of the most powerful demon slayers out there. He is the younger brother of Michikatsu Tsugikuni,who is gets turned into upper moon 1. Yoriichi is the mystirous demon slayer to beat Muzan in a fight 500 yeaars before the demon slayer story. Yoriichi is the one who made all the breating styles, like sun breathing which is the original breathing technique, every breathing style is just a rip off, of sun breathing.
"kokushibo is the upper moon 1, also known as the second strongest demon to ever excist, he was orignally called Michikatsu Tsugikuni when he was human, he is the older brother of Yoriichi Tsugikuni. Kokushibo's breathing technuique is called Moon breathing,Kokushibo is the great great grandfarther of Muichiro Tokito who is known as the mist hashira."
• "Breathing Styles are swordsmanship styles that makes use of an esoteric breathing technique known as Total Concentration Breathing practiced and taught by members of the Demon Slayer Corps and are used in combat by Demon Slayers (later passed on as traditional dances post-time skip). All known Breathing Styles currently taught within the Demon Slayer Corps are derived from Sun Breathing, the first one ever created. The majority of known Breathing Styles mimic a certain element of nature (i.e. flame, water and wind) and replicates it with the user's movements, techniques and abilities. The weapon attacks of Demon Slayers who use Breathing Styles are also longer ranged, possibly due to shockwaves or air pressure generated from their weapon itself when swinging and striking. New Breathing Styles are always being created to suit a Demon Slayer's combat needs,[1] which results in new weapons being utilized in demon hunting (i.e. flails and whips). Such Breathing Styles embody a bigger variety of concepts, like animals, plants and emotions (i.e. serpents, flowers and love). When utilizing a Breathing Style, users automatically visualize themselves manipulating the subject behind their style, making it seem as if they were using magic, though those that are less apt and proficient in their style will visualize less of it than one who is. It is possible to mix different Breathing Styles if the user cannot master one particular Breathing Style alone in order to use the stronger aspects of different styles to compensate. Tanjiro, realizing that he could not master Water Breathing like Giyu Tomioka nor could he handle the strain of Hinokami Kagura, showed to be able to combine the two techniques together in order to have stronger strikes than when he used Water Breathing alone and move for longer periods of time than if he used Hinokami Kagura alone. He did this to save Hinatsuru from Gyutaro[2], and later used it once again during the Infinity Castle Arc to slay dozens of demon."
