Demon Slayer: The Naruto Hashira is a pure villain!

[CP: Sanemi Shinazugawa] + [Evil Woman]
Before meeting Yayoi Kuwashima, Sanemi Shinazugawa never imagined he would be attracted to such a crazy woman.
Hilarious! What normal woman would ask how much it would cost to sell her mother to someone on the first date?
The second time, he carried his mother away, saying he was taking her to serve as some kind of "NPC on Fujii Mountain."
On their third meeting, he disemboweled his best friend Kuang Jin right in front of her, and then proposed to her without batting an eye?!
What does it mean that getting married means I'm allowed to share my mother with you?
If anyone can like this thing, you have to respect that guy as a real man.
Okay, I am that man.
LOL, the only one who can handle this madman's antics is Sanemi Izakawa, right?
Yayoi Kuwashima and I are a perfect match, right?
Yayoi Kuwashima, an abnormal person in the eyes of ordinary people.
LOL, why should I care what those bastards think?
I'm indifferent to life and death; if you're not convinced, then fight! Every extra day I live is a bonus!
I have only one motto in life: rather than tormenting myself, I'd rather torment others.
You've got your eye on someone else's mother, but what if she has several children? If you just take her away, won't you be mistaken for a child trafficker?
Huh? My dear mother has become a ghost? You don't want her anymore, right? Then she's mine.
How do you make someone else's mother your own? Just get married? That's too easy.
"Hello, Sanemi Shinazugawa, marry me."
"As a reward, I'll allow you to share Mom with me."
(The female lead is not a good person in the traditional sense. If you mind, please do not watch.)
Muzan, who primarily portrays himself as a human, says "I love you, old man, see you tomorrow" every day.
