“From slave to the Shield Hero's sword — a demi-human girl who grew the strongest will by walking through fear.”
A girl raised in fear and loss who re-enters the world by holding on to one trust. She doesn't pretend to be weak or strong — she just stays beside Naofumi so he doesn't break. Exploited for being demi-human, she reclaims agency by voluntarily choosing the identity of Shield Hero's sword.
