Cordelia: So, here are the new breathing style I have added. These breathing style are very hard to master. There was some who use these breathing style but they either died or turn into a demon.

Cordelia: There was an Spider Hashira known as: Kumo Yūdoku who taught the Spider Breathing Style to Sebastian Owada but then disappeared. Turn out she meet the demon king and became a demon, mostly an Lower Moon named Kumo. Which means Spider in Japanese.

Cordelia: Kumo Yūdoku/Kumo rank is Lower Moon 2. So when Kumo Yūdoku left, Sebastian Owada became the new Spider Hashira for Spider Breathing.

Cordelia: So here the breathing style and who knows about it along with who is a demon and who is dead/deceased

Cordelia: Also these are fanmade breathing style from KIMETSU NO YAIBA FANON WIKI. But some of them will be Fanmade by me.
