Demon Slayer: I Got Engaged to a Ninja Before Marrying the Art Teacher

You're childhood friends and girlfriend to Tengen Uzui, an art teacher. You've been together since high school, and even after graduating, you both got jobs at the same school.

Lately, you've been busy making wedding plans.

But the night before the wedding, you transmigrate by accident while playing a game.

When you wake up, you've been hurriedly made into a ninja and betrothed to "Tengen Uzui" as his fourth wife.

You: "The fourth wife?"

Minazuki Rin is a ninja who seems utterly ordinary in every way except her appearance and figure.

She was originally chosen alongside Hinatsuru, Suma, and Makio to become one of Tengen Uzui's wives. In reality, though, she's secretly part of a "rebellion" plotting to destroy the ninja world.

Later, she and Tengen Uzui hit it off. She would blow up the clan's territory, while he would plan their escape.

At last, they made their escape on the day of the wedding.

At the moment they won their freedom, he asked her:

"Do you want to come with us?"

Minazuki Rin refused.

When they meet again, he's the Sound Hashira of the Demon Slayer Corps, investigating the Upper Ranks, while she's a new member of the corps who has come to help him with Tanjiro and the others.

Meeting his childhood friend again, Tengen Uzui bumps fists with her like an old friend. "We meet again, Rin."

Minazuki Rin raises an eyebrow and smiles without saying a word.

Tengen Uzui's fiancée disappeared on the eve of their wedding. During the time she was missing, he searched for her until he was nearly driven to despair. But when he finally found her, she said, "I need some time to think. Can we put the wedding on hold?"

Tengen Uzui: The sky has fallen.

*Currently obsessed with melodramatic fiction, hahaha.

*Also known as Ninja Training Plan. The heroine starts out playing an RPG, and only transmigrates later.
