Demon Slayer Breathing Style

Breath of fun (楽しさの息吹)

Sorry, it's not romaji(With letters like these)  my Google translate only to hatakana (or something) so yeah.. And let's just say that the user is a female, okay? Okay

SORRY!
Also in note for third form there's a very small spoiler of season 2(I guess) the red light district I believe? And in "You're no fun" form there's mention of 2nd upper moon's blood art. Be warned
Written like this are mini-stories examples            just a spoler

2. Quick tag
User make an easy slash to make a demon think you're tired with make him lower 'his guard resulting easy k¡ll

3. Hide and seek
User stars to count down from ten to zero (if in the meantime demon attack then just dodges) then she very quickly goes for the k:ll also making hallucinations of her around demon saying "I'm here~' you can't hide" or something like that and puff, a slash in neck
(a bit based on sun breathing: fake rainbow; I think)

4. Funny dance
User is fighting- dancing then boom, sliced demons neck

5.Playing field
Concentrates on the place around the user quickly making a map of the place together with the indication of the positions in which the demons were in a given few seconds during the use of the technique, also recording the speed of moving things or living things in the user's head.

6. Clown
It's kinda similar to the 3rd form, there are just a hallucination of the scariest moments of human memory,
like when the demon was human 'he had a very scary situation with a certain person and had a trauma after this , And when he became a demon, he forgot everything, and suddenly when he was about to eat another man, he suddenly saw the face of an unknown person who, for unknown reasons, terrified him panicked and boom, shortened by his head.

6. Awesome joke
Like the water wheel form used on swamp demons in first episodes but can be used horizontaly and vertically standing on ground.

7. You're not fun
Form to fight to with a weaker upper moon, coloring hair endings in user's favorite color (mainly purple, light green, or yellow) making her at least 3× stronger than before, upgrading Senses For example, sight, smell or hearing, mind also works faster to keep up with the body, along with that the body also heats up |::|(so if Douma uses his ice art to put some ice to lungs it will easily melt lol)|::| , so after use coma for at least 2 weeks

8. Life is fun
Colors whole hair in one of the colors mentioned above, can spontaneously use any other form, to be faster also upgrades strength, speed, flexibility, reflex, senses like hearing, Smell, touch; and fast thinking 5 times,
by the way it's recommended to use it in life and death situation because after use there's a big chance of a Permanent damage to the muscles together with quite serious burns or frying the brain or the whole body, that is, death.

Yo I've tried to do it with descriptions already to see how could it be done.. I may  add mre but as you probably know by now I don't hurry much so.. For now it'll be like this ^^
Have a great day /or night, drink, eat and sleep!
