[Requests Accepted] [ちゃっぴぃ1] 俺、勇者の妹に転生したんだけど、どうすればいい? [RJ394724]

What is it like to live as the hero's sister? In this fantasy world, I have been reincarnated as the sister of a famous hero! I’ve been transformed into a girl and transported to another world. Of all things, I’m not the hero, but his sister! My dependable hero brother hasn’t come back at all... What am I supposed to do? Well, he’s the hero, and I think I’ll just live my life at my own pace (laughs). **[The Hero and His Sister]** The boy who was supposed to have died in the real world has been reincarnated as the hero’s sister, Chihiro, in another world! With a girl’s body and a boy’s heart, I have a complex personality. Soon, the Demon King revives, and my reliable hero brother sets off on an adventure... **[What is this Transformation Spring?!]** The "Holy Spring of Saint Karn," which the hero protects, has the effect of transforming genders. If a girl enters it, her body will change into that of a boy. - As a girl... I act as the hero's sister, this is my default appearance after the gender transformation during reincarnation. - As a boy... I act as a beautiful boy. Of course, I can wear boy's clothes. I am at risk of being targeted by various older women for reverse rape. **[Even if I stay indoors, my daily life is full of adventure]** People keep coming to my hero brother for help... The hero’s house is bustling with daily life! **○○ Girls who were saved in the past come to see the hero! ○○** Town girls who were kidnapped by thieves and saved by the hero.

Excited, they are bound to transform the hero’s sister into a boy and cause an explosion! **○○ Revenge from the villains ○○** Villains who have suffered greatly at the hands of the hero. Thieves, corrupt merchants, tentacle monsters, and others who harbor grudges against the hero attack the sister in his absence!
