Sword Fan — Reborn as a Sword

About the work

An adventurer dies trying to save his friend, but his soul is reincarnated as an intelligent, talking sword, nicknamed "Teacher" by Fran, a young enslaved catgirl he meets and frees. Together they explore a fantasy world full of labyrinths and creatures, the sword passing on its combat knowledge to Fran as she learns to fight by his side.

Written by Yuu Tanaka, this isekai series stands out for its original premise — a protagonist literally turned into an object — which refreshes the genre by exploring a touching mentorship between a sentient weapon and its young wielder. Its blend of adventure and heartfelt storytelling has earned it growing success in light novel, manga and anime form.
