So all I could find (not understanding the language) is that you speak to Satan in the house to start chapter 3, a new teleport appears in the base ment to a new forest, with areas seemingly split into A-d, 1-5. Theres no enemies though, and all I have found so far is a chest in A4 with a weapon in it. Theres a few pools you can walk to the center of, but nothing to interact with. I'm probably missing something.
EDIT: theres also a key item in B4
I did some running around, the city near the bandit base (where you need the gym clothes) can be rebuilt via sidequests, which is the gold star quest you get, but otherwise I am clueless as to what to do next. Trying that google translate lens thing tells me theres a cafe to visit, but i have no idea where.
EDIT 2: Eventually figured it out. For the gold quest Satan gives you, you talk to a lady in the ruined town (top left most teleporter in the basement) and for the silver one that seems to be main story, you go back to the first town (top right most portal) and go to a cafe. go behind the counter, talk to him, then you get a quest to get an apron. You get this near the big market area (can teleport there from the cafe if you have debug crystals enabled) and it continues from there.
