Clover Slayers kahonoelle <3 Kahono and the rest of the underwater sea temple are the sword-smiths, who get their village attacked by Vetto (Upper 4) + some other demons. (More about au under cut)
This is also for bc femslash month (Prompt is Crossover) @bceventshub
Kahono is Noelle's assigned swordsmith, and while giving Noelle her sword (which is freely given by the corps) she asks for an insane amount of money (adjusting for inflation at the time) which SHE GETS (Noelle has no idea how the demon slayer corps works since she's been purposefully sheltered from it her whole life).
Kahono has the same passion of haganezuka when it comes to sword making, but way less annoying. Whenever Noelle breaks her sword though, she IS a little miffed, and keeps asking for an increasing amount of money whenever it happens. However along with her passion for swords, another passion she has is making instruments, and singing, which she doesn't get to do often considering most money goes to make swords, and most time aswell. Part of the reason she asks for money is to save up so she can pursue music aswell as make swords in the future without anyone telling her off for using corps budget.
Kahono makes/hones swords, and Kiato, as the eldest is in charge of learning how to operate and maintain the training doll: Licht type zero.
Also in the main piece where Kahono is repairing/sharpening/wtv the sword (where she is showing a wild amount of devotion to making the best sword for her swordsman), the sword was used by either Undine (Sengoku Water hashira) or Leviathan (Undine's predecessor). Noelle uses this sword after the swordsmansmith village arc in this au.
