Demon Slayer: The Older Brother Becomes a Demon King and Gets Spoiled

🔥 Demon Slayer + everyone survives IF route + Tanjiro turns into a demon + all-Tanjiro doting route + told from the perspective of Takeo

On that snowy night, the gears of happiness slipped out of alignment.

Although the Kamado family survived, the price was... the kindest eldest son, Tanjiro, became a demon.

“Why not become a demon if it means I can protect my family?”

But he is not an ordinary demon.

He is a godlike Demon King who has overcome the sun, is not afraid of wisteria, and even retains the memory of Breathing Techniques.

He loses his memories, yet keeps the kindness carved into his soul, driving everyone who meets him (and even demons) crazy.

❤️ Emotional arrowheads (All -> Tan): everyone’s one-sided love! Includes Takeo x Tanjiro, Giyu x Tanjiro, Rengoku x Tanjiro, Inosuke x Tanjiro, Zenitsu x Tanjiro, Muzan x Tanjiro, Rui x Tanjiro, etc. A chaotic mix of pairings, all canon couples broken apart, everyone just wants to spoil Tanjiro.

If it’s for my brother, I’d even overturn this broken world completely!

This is a story of redemption, protection, and being loved madly by everyone.
