[Demon Slayer X Honkai Impact 3rd] The Child Who Was Spirited Away

He was a child raised by immortals, an outcast abandoned by the world.

As a child, he accidentally discovered the truth about the world and was spirited away. Years later, when he unexpectedly stepped back into the world that should have been his, he found that everything seemed to have changed dramatically.

His younger brother had never inherited the family and had disappeared long ago. Meanwhile, the Tsugikuni family had gained a “firstborn son” who looked exactly like him.

It was as if the world had automatically patched over the hole his absence had left. The boy, now named Yae Lan, set out to uncover the truth behind it all.

The Demon Slayer Corps, passed down through the centuries; demons lurking in the dark; cursed spirits invisible to ordinary people; ancient places of inheritance...

“Brother? It's been a long time.”

The young man, a crimson flame-shaped mark on his forehead, gazed at the familiar boy before him with a complicated expression.

“Ah... It has been a long time.”

“Yoriichi.”
