Starting with Demon Slayer: A Sun-Breathing Armor Set from the Start

Karna. . . . Being on the ceiling of heroic spirits, using his Noble Phantasm to defeat Wu Pai would be overkill. . . .

In the Demon Slayer Chapter, Muzan said he was the ultimate creature, and I suddenly thought of Kaz-sama.

Why does Fei Lu's pig's feet always like to reveal all his information without reservation? Is he showing off, or does he think that no one in the world will harm him, and he doesn't have the least sense of defense?

How should I put it? Heishimou used to use the Breath of the Sun before, but he no longer needs it after turning into a ghost, because the posture of the ghost is different from the human breathing method. In Chapter 11, it is fine if you write Kagura, the God of Fire, as the Breath of Fire, but teaching it to Nezuko is a bit poisonous, right?

Klin traveled through ghost annihilation and watched me use my ultimate Sun Fist, all the ghosts were wiped out. Bulbasaur travels through demon annihilation, watch my unique move, the sun's blazing fire, and kill all the demons without a burial place. Doraemon travels through ghost slayers, look at my prop time machine, all ghosts must live in the daytime all their lives. . .

I also think our worldview is very strange. Isn't my life the enemy's life? And eight million personalities is a bit exaggerated. It's impossible to create a Heroic Spirit Noble Phantasm.

Isn't Kagura, the God of Fire, the breath of the sun?

The scar on Kamado Tanjiro's head seems to be natural. From the ugly scar at the beginning, it gradually turned into a tattoo-like one, seemingly changing with his strength.

Forced to let go without mercy! Even ordinary sunlight can kill Wu Ke, but he can actually escape under the rays of divine sunlight?

I also want to say that Karna's weapon is a gun. Why should he use a Nichirin sword?
