What locations and where are the clothes / resources located? (any)
You can buy a Police Uniform (Best DEF for a long time) after you save the sunglasses girl early in to the main missions.
You can steal a Doctor's Coat from the start by entering the Hospital and going right into Room 3. Use the locker inside that room. Those are both early in the game. If you want to buy items, use the Vending Machine outside and the girl inside of the Mart store you started the game at.
If you meant the clothing for the girls that's a hassle because of random spawns... I couldn't find the final missing hat myself. My advice is to buy the Blue Club off the main oni girl and just run around smacking random women. It's good exp at least. Or download a complete save from a few pages earlier, if you've already beat the game.
I haven't tried the last option come to think of it mostly cause I always assumed you get the police called on you.
She uses her mouth on you and you aren't charged for the "treatment". Doing this seems to bug the game though, you can't ever get treatment off that nurse again in 1.0.3.
By the way it seems V1.0.4 "special version" is out on Patreon. Think it adds some new positions, not sure what else. Not sure what tier you need to see it but jezus £15.50 tier to access a cheat menu is pretty criminal. The game isn't near hard enough to justify needing cheats, in fact I'm hoping they add a HARDER difficulty to it at some point.
