Sanemi Shinazugawa

Every demon must be killed. No exceptions.

📍 His declaration the moment he sees Nezuko — the absolute hatred of someone who has lost his family to demons.

Genya... you idiot.

📍 His monologue when he learns his estranged brother joined the Corps — an entire complicated relationship compressed into two words.

If you don't want to die, get stronger. That's it.

📍 His version of comfort — practical instruction instead of empathy. Cold-sounding, but it's exactly how he survived.

I was the one who killed our mother... even after she became a demon.

📍 The tragedy revealed in flashback — his hatred of demons comes not from rage but from grief he cannot voice.

Hostility Toward Nezuko

At the Hashira meeting, he immediately moves to execute Nezuko for being a demon, and violently confronts Tanjiro. His first scene establishes just how deep his hatred runs.

The Real Source of His Hatred

When his mother, turned demon, attacks his remaining siblings, Sanemi kills her himself. The first revelation that his absolute hatred comes from grief, not anger.

Standing Against Upper Rank 1

He faces Upper Rank 1 Kokushibo alongside Gyomei, Genya, and Muichiro. At the limit of survival, his hidden feelings for his brother Genya finally surface — the climax of his entire arc.
