This Is My Path as a Heroic Spirit

An Zhiyu transmigrated to the Land of Shadows. Day after day, year after year, he trained with his master, Scathach. Then, each evening after martial arts practice, Morgan le Fay would teach him magic. At first, he got along very well with Morgan, and came to think highly of her.

That was until one day, when Morgan suddenly said to him, "The selection of the king is in one week. My younger sister, Artoria, will pull the sword from the stone and become king... I need you to do something for me."

"What?" An Zhiyu asked.

"Get the sword from the stone before she does, then marry her."

"???"

"The curse has taken hold. Starting today, you must find a way to make Artoria your wife!"

This is a world where timelines have become tangled together. An Zhiyu had pulled the sword from the stone, put a stop to the conflict between Scathach and her sister, and even helped Gilgamesh. He thought he would keep going on adventures like that forever.

Until one day, he was summoned by the Holy Grail.

Looking at the familiar faces before him, An Zhiyu awkwardly waved. "Hello..."

Artoria smiled and raised the Holy Lance in her hand. "Shining Spear of the End!"
