(parody from Luc Vaspori. Tanjiro and other characters are above 18+ years old)
Tanjiro Kamado is a young dummy thicc demon slayer with a godly charisma... His Rizz
Tanjiro: "Hey! Get your hands of my little sister! Only I'm allowed to touch her like that!"
Giyu: holding Nezuko in a restraining hold "wait. What do you mean by that?"
Tanjiro: "oh. Um. Nothing. Forget i said that. •w•"
Giyu: "nah. Get that incest breathing sh#t outta my face."
Later, after Tanjiro joined the Demon Slayer Corps and after the events of Tanjiro being in a coma and waking up from it...
He likes both men, and girls. (Giyu can't be affected by his rizz. Only Inosuke can counter Tanjiro's rizz with his rizz)
Mitsuri: "Tanjiro, i heard you were promoted to Hashira after Tengen retired."
Tanjiro: wearing his usual friendly smile "It's true."
Mitsuri: "so what type of Hashira are you?"
Tanjiro: "I'm the Rizz Hashira. Rizzing dat a## is my specialty."
Mitsuri: blushing furiously "wow~ you're so manly!"
the next day...
Himejima: "Tanjiro. You make me weep."
Tanjiro: wearing his usual friendly smile "why is that, Mr. Himejima?"
Himejima: "it's just... Thy dumpy is so $$fat$$."
Tanjiro: "But Mr. Himejima! You're Blind!"
Himejima: "I don't need eyes to know you've got a fat a##."
In a fight with a Urogi...
Tanjiro: holds his sword until it bursts red fire all the sudden "whoa."
Urogi: "planning something? Your Rizz Breathing may work on Aizetsu."
Aizetsu: blushing demon boi
Urogi: "But it won't work on me!" Flies towards Tanjiro
Tanjiro: "is that so? Then i guess I'll have to use my new move!" Readies his sword as his mark appears on the left part of his face "Dance of the Rizz God!" Creates a dragon formed slash around Urogi in a curved manner with his flamed sword and dramatically poses with it
Urogi: "Holy sh#t! You're so sexy-iee!"
Basically, everyone in town and all around. Including the demons. Know of Tanjiro's Rizz Breathing, and The Demon Slayer Corps make good use of that
