Harry Potter Reacts to Harry Potter as Yoriichi Tsugikuni (Part 2?) *Important Note in Description*

I know a lot of you were waiting on the Will Graham as PM! Dazai video but that's on hold for a bit. I don't know why but doing videos about Dazai gives me so much trouble. I think Dazai hates me, lol

AU:

-Battle of Hogwarts never happened. Dumbledore is alive. Snape is alive.

-Set during seventh year of Hogwarts (for Hermione, Ron, Dumbledore, and Snape) and a bit after Yoriichi gave Muzan PTSD (for Voldemort/Muzan).

Voldemort as Muzan:

Voldemort found out that the golden trio knew about his Horcruxes too late. 4 out of the 7 had already been destroyed: the diary, the ring, the locket, and the cup.

Finding that this method of immortality was not sustainable any longer, Voldemort performed a dark ritual to recall his remaining souls pieces: the diadem, Nagini, and the piece he unknowingly placed in Harry Potter.

After the ritual Voldemort regained his mostly human visage; though the Red snake-like eyes and pale skin remained.

Voldemort started searching for a way he could gain true immortality. Eventually he came across a theoretical potion that could grant him the true immortality he desires.

Snape, tasked by Voldemort to create this potion, alters the ingredients slightly (taking the blue spider lily out of the potion). Snape creates the potion, granting Voldemort immortality, but not true immortality; sunlight being Voldemort's only weakness.

Voldemort, angry at the sabotage, tries to kill Snape but Snape gets away (Voldemort was weak from the transformation).

Snape runs to Dumbledore to inform him of what happened.

After figuring out how Snape altered the potion, Voldemort goes to Japan in search of the blue spider lily; creating other demons with his blood to assist with the search.

(Voldemort now goes by Muzan Kibutsuji)

The Ubuyashiki family—related to Voldemort through a squib line—created the Demon Slayer Corp to combat Muzan and his demons.

Harry as Yoriichi:

(Harry was born with the flame-like marking on his forehead. Everyone assumed it was just a birthmark.)

After hearing about what happened to Voldemort from Dumbledore, Harry, without telling anyone, follows after Voldemort to Japan.

After encountering a demon slayer and finding out who they were fighting against, Harry decided to start training with a sword to join them.

Even with having never picked up a sword before, Harry was able to overpower his sword instructor, causing him to go unconscious and inflicting many injuries all over his body.

Harry eventually invents Breathing Styles, modifying the original Breathing Technique—Sun Breathing—to suit the individual abilities and strengths of others.

When Harry used Sun Breathing for the first time his hair and eyes turned red.

Harry changed his name to Yoriichi Tsugikuni to keep a low profile and not alert Voldemort to his presence.

~the rest of Demon Slayer is Canon~

Additional Information:

-Dumbledore, Snape, Hermione, and Ron know Muzan Kibutsuji and Voldemort are one and the same.

-Voldemort/Muzan doesn't know Harry is Yoriichi.

-Voldemort gave Nagini some of his blood, causing Nagini to turn back into a human form. Nagini now goes by Nakime.

-No one at Hogwarts has heard from Harry since he left.

-Michikatsu Tsugikuni is not Harry's brother but a fellow student training under the same sword instructor. Harry looked up to Michikatsu greatly, admiring his sword skills. Harry started using the last name Tsugikuni after Michikatsu became a demon to honor and remember the man Michikatsu was before becoming a demon.
