Since the user is asking for a guide, maybe they're referring to a specific scenario in a game or a story where a character (like Rena Fukiishi) is involved, perhaps from a visual novel or an anime. "Playcrot fixed" might refer to a game called "Playcrot" that has been fixed (patched) to allow certain actions or scenarios. However, I can't find any official information on "Playcrot" as a known game. It might be a typo for "PlayCrash" or another similar name.
