Demon Slayer: the Light That Shines in the Dark Night

In the Demon Slayer Squad, everyone knows two things: First, Butterfly Nin's mouth is very poisonous; second, the childhood sweetheart beside her who is always smiling - Yue Bai Mio, is even more "poisonous". Others relied on ruthlessness to kill ghosts, while he relied on speed to kill ghosts; others relied on masters to practice breathing, but after he learned the breathing of thunder, he just trained himself to "flash". Do you think he is a cold-faced genius? No, he is like a little sun. When he smiles, he can illuminate the darkest corners of people's hearts - and by the way, it can also illuminate the heads of ghosts. Then the ghosts gradually understood: Being targeted by the Butterfly Ninja might just be poisoning; Being targeted by Yue Shiro Mio... You didn't even have time to say "Huh?"
