First off. The menu music? INCREDIBLE. I want a copy of it.

An old woman tells you to take a box, and to open it when you're alone in your room.

We know the real reason she's saying this, gooners. But you are given several questions about just opening the box. And any time you say no, you go back to the main menu.

Trying to find any sort of discussion on this one, both japanese or otherwise was very tricky. So I just translated the manual, and hopefully can give anyone else trying to get though this a head start.

Instead of jumping right into the gameplay, I will go ahead and give you a rough translation of said Manual. An excerpt from the manual is shown in the intro to the game, with the old mage woman giggling and beckoning you over.

Introduction

Wait a moment... You there, walking that way... It's you. Don't worry, I won't trouble you. Just sit there for a moment-- No, it's nothing... It's just that you are so incredibly amusing. Excuse me. You just looked so profoundly unhappy that I couldn't help but become curious... Hmm... I thought so. You are quite a devious man, aren't you. You... No, no. You don't have to answer... I can see right through you... I can tell just by looking at your face.

After you get roasted by grandma repeatedly about how hopeless you are as a romantic, you open the box in the safety of your own room.

After you get roasted by grandma repeatedly about how hopeless you are as a romantic, you open the box in the safety of your own room. The small love demon (Renma) named Cure appears in a bath. She asks you questions about your type, and says that her magic to charm the girl will only last if you don't mess up enough times talking with her. Basically, each girl is different with different likes and dislikes. Begging is good for some of them, being more assertive makes others happy, and some are apparently a mixed bag. The manual gives you a rough idea of how to approach the archtypes, but it can be easy to get locked into a phase with all the options. By the way, in order to progress I made a rough english translation of the game's Manual. My collection is from Archive.org, and includes the manuals. I love and miss manuals. They made the old woman and Cure the demon narrate a lot of the instructions. The manual's script is pretty much exactly what you read in the opening of the game.
