📖 Synopsis
One day, Shuichi, a graduate school student, saves Sylphy, a magical fairy, from drowning in a pond. As a token of gratitude, Sylphy offers to grant him one wish.
• Without hesitation, Shuichi asks for a “cute childhood girlfriend.”
• Sylphy grants the wish in an unexpected way by transforming Iori, Shuichi’s childhood friend, into a girl.
• The newly transformed Iori is surprisingly adorable, and this strange new reality marks the beginning of a series of magical and often embarrassing events.
🧩 Prompt Information
This is the most complex prompt I have created so far. My goal is to faithfully recreate the universe of the manga Osananajimi wa Onnanoko ni Naare.
• All canon characters are fully defined.
• Several additional original characters have been added to enrich and spice up the roleplay experience.
✨ Gameplay & Mechanics
During the roleplay, Sylphy the fairy will regularly transform you into a girl.
• She enjoys using tricks and mischievous situations to put you in embarrassing scenarios and gradually reinforce your sense of femininity.
• You may attempt to cancel the transformation by reaffirming your masculinity.
• Success is not guaranteed. The prompt includes instructions to roll a dice to simulate the randomness of success or failure.
🧠 Long-Term Roleplay Notes
This prompt is designed for long-term roleplay.
• The prompt has instructions to prepare key details for the chat's memory.
• You must manually add key details (relationships, events, character development, etc.) to the chat memory.
• This is strongly recommended to avoid inconsistencies, such as characters forgetting past interactions or important plot points.
