This is my oc Konturu Tsugikuni, but as a demon :O Since he still has access to sun breathing, he's immune to sunlight, meaning he can fight demon slayers in the day time, also meaning that he's almost impossible to beat, kind of like Demon king Tanjiro :D he even has access to his demon slayer mark. His blood demon art compliments his sun breathing styles, because his blood demon art allows him to create flaming sun shaped blades that mix in with his breathing styles. He can also enhance his sun breathing into a demonic form of sun breathing known as dark sun breathing, which is way more deadly than his sun breathing. He can also change his sword's appearance, making it have four blades sticking out of his original, two on each side. Made Up Sun Breathing Forms Regular sword (It's sun breathing but remastered :D) 1st form: Solar flare: He dashes forward in a zig zag pattern at high speeds and slashes the target, causing wherever the blade slashed to get 3rd degree burns. 2nd form: Summer heatwave: He spins his blade in a circular motion which creates a vortex of fire that sucks up and blasts back any enemy that gets caught in it. 3rd form: Drought: He swings his sword multiple times and releases three sword slashes that shoot toward an enemy, drying up everything around them. 4th form: Constant heat: He charges toward an enemy while the fire emitting from the sword creates a dragon-like head that he slams down onto the enemy, creating a massive crater. 5th form: Sunny sky: He swings his sword in a vertical, circular motion which creates a circular slash that cuts and burns everything around it. 6th form: Solar eclipse: Hes wings his sword multiple times in quick speed, creating a huge slashing shield that blocks incoming attacks. 7th form: Solar wind: He jumps up into the air, or hangs onto something, and swings his sword in a horizontal arc formation, creating super heated air currents that blow the enemy back at a distance at the same time scorching the enemy's skin. 8th form: Sunlight: He slams his sword onto the ground which makes it glow really bright, which blinds nearby enemies. 9th form: Sunburst: He swings his sword in the way that you swing a baseball bat and it causes an explosion of heat that massively burns the enemy. It will do even more damage if the enemy is hit directly with the sword. 10th form: Daytime dragon: He swings his sword in different directions, creating a dragon-like figure all around him. He uses his sword to control the dragon cloak. It only lasts for 2 to 3 hours tho. 11th form: Warm rainbow: He swings his sword one way, creating one slash, while another slash appears on the other side of him. Whenever the slashes hit, they explode in rainbow colors, temporarily blinding the enemy. 12th form: Mirage: He points his sword at the enemy, which the sword emits heat off of it and whenever an enemy hits him, he creates a clone of himself that gets hit while the real Konturu gets behind the enemy, giving him a chance to slash them. By the time the enemy notices it's too late. 13th form: Sun shuriken: He spins his sword in a circular motion and throws it, slicing through anything it comes in contact with, at the same time burning it. It will also return to him like a boomerang. 14th form: Scorching heat: He slashes at the enemy multiple times, causing severe burns wherever the enemy has been slashed.
