Reincarnation of the greatest Swordsmaster (as a Fox-girl)

Swordsmasters,
Beings that have attained unrivaled power with the sword.

They live, eat, sleep, and die with their swords.

Swordsmaster Nova was one such being, fated to die on the battlefield with his sword. However, one faithful encounter with the Hero's party changed his life forever.

He learned friendship,
Camaraderie,
And he learned how to love.

Yet, fate is cruel. In the final battle against the Demon king, he sacrificed himself so that his friends can escape.

Five years after his death, he is reborn as a baby; a grandson of an Otherworlder; a child of a prestigious Swordsmen family—with all his previous life's memories intact.

Will he spend his new chance at life like before, rolling around desperately on the battlefield?
Will he leave his past life behind and make new connections?
Will he try to contact his retired comrades?
Or will he do all of those above?
