Adult PC Game: The Hero We Need v6.63 by Brandygang Archive

The Hero We Need 6.63
Heavily inspired by games like Monster Girl Quest, Ascendas Descent, Order of Light, Alone Amongst Demons and Helpless Heroine. Warning, NSFW+ with some heavily dark/depressing fetish themes, if you don't like enslavement, bondage, identity death (or literal death in some cases) or erotic brainwashing this game isn't for you.

The game follows "Bernida", as she's been transformed and redubbed on her quest to defeat the Demon Lord, Dark Queen Heliot. Stuck as girl and sucked into a strange world far from home with her new partner, a mousy maid, she's got nothing to do with her time but train and hope to overcome the plentiful baddies ahead. Adventures aplenty await!
