Kasumi: This battle is brought to you by Starzal!

Ann: With two power-loving demons who love to fight and are only held back by the sun itself!

Name: Akaza, Hakuji, Hakuji Soyama (Kimetsu Academy)

Origin: Kimetsu no Yaiba

Gender: Male

Age: 18 years old as a human, at least over 133 years old as a demon

Classification: Human (Formerly), Criminal, Martial Artist, Demon, Twelve Kizuki member, Upper Moon Three

Ann: Starting with Akaza, one of the Upper Moons in Demon Slayer!

Kasumi: And one of the top guys who like to make human-sized flaming donuts! Hey Ann, do you think you'll ever be a flaming donut?

Ann: Don't even joke about that!

Kasumi: Anyway, Akaza is a demon who enjoys the thrill of battle! As a demon, he has superhuman speed and strength. He also has a healing factor that lets him heal through... almost any injury.

Ann: He's highly skilled at hand-to-hand combat and has extrasensory perception. To the point that he can predict the moves of others as well as where they are, their blindspots, and their weak points.

Kasumi: Right. His Blood Demon Art is centered around Martial Arts, combining his devastating shockwaves with the Soryu-style fighting style he had when he was human.

Ann: He's definitely a demon when it comes to combat.

Akaza: You're misunderstanding something, Tanjiro. The only people I hate are weaklings. I only spit in the faces of the weak. Yes. I'm repulsed by weaklings. They make me vomit. The laws of nature dictate that they will be eliminated.

Name: Wamuu / Wham

Origin: JoJo's Bizarre Adventure: Battle Tendency

Age: 12,000+ years

Gender: Male

Classification: Pillar Man

Ann: Then there's Wamuu the Pillar Man! Okay, he's not technically a Demon but he certainly is close to one.

Kasumi: Wamuu is a fighting genius with immense physical strength. He also has full control over his own body and can fuse the bodies of those around him.

Ann: He also has headgear that protects him from the sun since... well... he's weak to the sun.

Kasumi: But his main ability is his control over wind. Not only can he make giant wind storms, but he can make a wind suit and even blades of wind. Honestly he's a better antagonist than Kars, but that's only my opinion.

Wamuu: Become stronger before you decide to face the mighty Wamuu again, child. That way, you can be worthy of my time as I destroy you with honor.

Ann: Alright is everyone ready? It's time for D-B-X!

In an ancient Pyramid, blocking the smallest light of Egypts hot sun, Akaza and Wamuu went to face each other.

Akaza: Heh... you look pretty strong. I think I'm gonna have some fun with this one.

Wamuu: Foolish child. You'll find you are outmatched against someone like me.

Akaza: Ha! We'll just see about that.

Akaza dashed at Wamuu and went for a kick, which was immediately blocked. Wamuu went for a chop and smashed Akaza into the ground. He was about to stomp on his face but Wamuu recovered and jumped back to his feet.

Akaza: Impressive, but not good enough! Air Type!

Akaza punched the air unleashing giant bursts of wind that Wamuu blocked.

Wamuu: Divine Sandstorm!

He unleashed his own burst of wind and blew Akaza into a wall. The demon caught himself and lunged at Wamuu, going for a heavy kick. Wamuu blocked it and caused a shockwave around them.

Wamuu then went for another punch but Akaza countered with his foot. They clashed and knocked each other back.

Wamuu: You're strong. I can tell you're no mere human!

Wamuu picked up a pillar and threw it at him. Akaza was quick to react as he punched the pillar into pieces before dashing at him. Both of them went for multiple punches and clashes.

Akaza: Bold comparison! But no human can match up to a true demon!

Akaza went for a punch to the gut, but Wamuu released his wind suit, causing Akaza to be knocked back as soon as he made contact.

Akaza: What?!

Wamuu: And no demon can scale... to the might of a pillar.

Akaza went for multiple strikes but each one only knocked him back. A quick wind then cut his arm off.

Akaza: Geh! Hehe!

His arm grew back almost immediately as another quick wind went at him. Akaza went for a punch and clashed with it.

Wamuu: Nani?!

Wamuu sent more quick gusts of wind but Akaza kept countering with his fist.

Akaza: Ahahaha! This is fun! But all good things must come to an end!

Akaza dashed at him as Wamuu's wind suit vanished. They clashed fist twice as Wamuu went for a third. Akaza dodged it and punched him in the face.

Akaza: Die!

With that single punch he sent Wamuu flying outside and burning to ash under the hot sun.

Akaza: Ahahahaha!

Ann: And that's finally done.

Kasumi: Finally the left guy won...

Ann: Now who's next!
