I've said it many times and I guess I'll say it once again.
Note that this is not a perfect step-by-step guide, it's more like a short guide to give a player a clue about how to progress in this game.
The game progress of this game depends on seeing scenes every day and sleeping often.
Not required but highly suggested is that you visit the blacksmith every day and continue to upgrade the sword until it's maxed out. By the time you can leave the village, your sword should be pretty much a max level which will allow you to easily beat the monsters once you can leave the village.
Scenes you need to see after doing the two quests at the start:
Inn Bath - Inn old man in the top left room
Inn Bath - Inside the Public Bath
Temple doctor Doratomu
Farmer Mon - Near north watchtower
Military Academy - Aramis (talk with him in the sparring area) then you need to go upstairs and enter the room
Military Academy - Classroom on 2F
Military Academy - Woman Bath - Boy Peta
After advancing scenes with all of them up to a certain point, one day when Sarah wakes up and leaves her room she will see Mierupa take Malena to her room and if you go up to that room and click on the door, she will hear panting sounds and obviously guess they're having sex.
After seeing that scene, then the next time she visits Aramis at the academy and goes up to that resting area where they had sex, she will tell Aramis that she saw Mierupa and Malena have sex. Aramis will explode and run to Sarah's house and beat the shit out of Mierupa. He will then end up having sex with Malena himself and Sarah will come back home after him and hear them have sex.
After that, Sarah will break up with Aramis and she will allow other villagers above to put it inside. Now again you're up for grinding scenes. You have to keep going to all the NPC's around the village and advance scenes and go to sleep.
The farmer near the north watchtower will at some point tell Sarah to visit him at his ranch that's south of the village. He will also tell her to buy red panties when she comes to visit him. The next day after seeing that scene, Sarah will be able to buy red panties from Mierupa at his shop. She will end up getting the panties for free.
Keep visiting all the NPC's around the village and get all the scenes. At some point when you visit the farmer, there will be a cutscene where some Mysterious guy and Rentan watch as Sarah and the farmer have sex. Some days later, when you visit the farmer and if you've advances other scenes in the village to a certain point, the farmer will be wounded lying on the ranch. Sarah will take the farmer to the doctor and run to the military academy to walk with Aramis there who's in charge. Aramis will tell Sarah that he can't do much and Sarah will get angry and decide to take the matter into her hands. She will decide to go herself to Maronite village and prevent any further attacks on the village. Before she can take the northeast exit out of the village, you have to go with Gordon on the date. After the date, Gordon will tell her that he will cover for her while she's out of the village at night by turning the lights in her room to appear as if she's at home.
After seeing that scene, Sarah will be able to leave the village through the northeast exit.
To be able to leave the village through the north exit above the temple, you need to talk with the prelate after Heitosu leaves the village and after Sarah breaks up with Aramis. If you talk to the prelate the day after that, the prelate will tell Sarah about the red crystal being moved from the temple, and then she will be able to enter that area.
This is as far as I'll go with the guide. I already wrote a mini-guide with all this information but it seems no one is reading that.
