Sun Breathing Styles:

First Form, Dance: It is one of the simplest forms where the user delivers a single vertical slash.

Second Form, Clear Blue Sky: Much like the second form of water breathing, the technique involves a 360-degree rotation to amplify the vulnerability of a slash.

Third Form, Raging Sun: No fighting technique can be effective just by relying solely on the attack. So, Yoriichi created the third form, which involves horizontal slashes to hit or defend from incoming attacks simultaneously.

Fourth Form, Burning Bones, Summer Sun: If the previous form was the perfect balance of attack and defence, this one is entirely defence-centric, where the user unleashes a large circular slash that defends from imminent frontal attacks.

Fifth Form, Setting Sun Transformation: Focusing mainly on agility and swift movements, here, the user back-flips in mid-air to land a powerful slash.

Sixth Form, Solar Heat Haze: This technique deceives the opponent with a simple slash that seems to miss but actually hits the target when the time comes.

Seventh Form, Beneficent Radiance: Have you ever seen how a pack of wolves surrounds its prey? This unique stance is highly inspired by the same idea, where the user has to surround the enemy with a slash.

Eighth Form, Sunflower Thrust: As you can guess from the word "thrust' in its name, the technique involves a single thrust attack with the pointed end of the sword.

Ninth form, Dragon Sun Halo Head Dance: This is a flashy technique that takes the form of a Japanese Dragon made from solar flames. It is a tailor-made move for dealing with 1 vs. many fights.

Tenth Form, Fire Wheel: Similar to the Water wheel, the Fire wheel involves swinging the solar flames sword. It is superior to the second form of Sun breathing in terms of power generated but requires a lot of stamina to pull it off.

Eleventh Form, Fake Rainbow: The concept of using afterimages in battles has always been popular in the shonen genre, but little did we expect to see it in the Demon Slayer series too. This technique creates after images to distract the enemies and has succeeded in deceiving even the sharpest eyes.

Twelfth Form, Flame Dance: It is a simple two-combo strike that starts with a vertical slash and then a horizontal one right after.

Thirteenth Form: This isn't a separate form; rather, it's the combination of all 12 forms of Sun breathing since using just one form at a time isn't enough to kill the sinister creature. This anti-Muzan technique is developed keeping his body structure in mind so that his 12 vital organs (7 hearts and 5 brains) can be completely destroyed despite their self-shifting ability.
