I plan on making a story using the universe of KNY/Demon Slayer and I've decided on making my own breathing style. I don't know if it's been used before but I'll be making my own forms or using names from other animes for the Forms.

P.s: This'll be an off-shoot of stone breathing so anime only fans may. MAY. Be spoiled. Also I've only got the names down for the 4 forms I've got.

Breathing Style: Steel Breathing.

1st Form: Steel Cutter: The user leaps as high as they can into the air and uses the downward momentum to increase their speed and strength unleashing a single strike upon their opponent.

2nd Form: Gleaming Flash: When attacking an opponent if they prepare to counter or defend from an attack the user can quickly change their posture or sword angle to throw off their opponent's and catch them off guard.

3rd Form: God Speed 10 Slashes: The user uses their maximum base speed and strength to unleash 10 powerful slashes damaging an enemy greatly.

4th Form: (this form utilises strength over speed) 1000 Divine cuts: This is a technique used for a quick and easy fight. By utilising Total Concentration Breathing and increasing their maximum speed they can unleash consecutive slashes at such speed and that weak demons will be reduced to hundreds of chunks.
