At the moment just found a reg edit file. If you want to trust just need to google "初期の訪問者 save".
One of the first link is this one :
You must be registered to see the links
Scroll down to the orange botton and click on it to be redirect to mega an download the file.
The file only will add the maximun level to your existing profile. So from there you can upgrade to the top the nasty skills to "enjoy" them and have an easy run of the game.
Also there is a bonification/minigame scenario. And you can also change you inner clothes color or use bikini.
I didn´t drive myself crazy to find my save so I gonna explain how to unlock and find those things.
1---For unlock everything you will need money and 2 golden ingots.To do this fast just spend all the points on your gun and the ecchi skills.
2---To be able to use the ecchi skills you will need the pink potions so, go to the open world map and left hand side to the dungeon portal. It´s located passing the river.
Beat the dungeon with your guns .
3---Now you should have some money to go to the small village in front of the dungeon portal to find a tiny potioncrasft girl with short black hair in the middle on the town. From her you will buy a few lvl 4 pink potions, 3 should be enough but buy as many as you want.YOu could buy some red potions for heal yourself in the future. Drink one of the pink potions to be able to use the sexy skills (TAB MENU).
4---Now go back to the dungeon portal, but don't go in, just go right following the map border to find a portal at the "egyptian area". Enter the portal and beat the boss ( it's the easiest way to farm money, golden ingots and materials for more stuff ). Just use the ecchi skills and will be pass out in a few minutes. May you will need to repeat the boss if you run out of money.
---Bikini--- If you just respawn at the beggining of the map or just outside of the boss go to the left side until the end of the map.You will find a destroyed city. At the right botton, hided behind a build you will find a NPC with the bikini clothes for 2 golden ingots ( if you don't have enough ingots, there is a blacksmith at the town that will give to you for materials).
---Clothes color change---At the respawn base there is 2 NPCs that are selling those item. You can change the inner cloth and bikini color.
---Bonification scenario--- This one it's more hard to find so:
5---Go to the 2 merchant NPCs at the respawn base, you need to buy a green metal tube. You need 10 in total. It's the same metal thing that you use to create portals if you find the portal gates.
6---Now go back to the space ship and talk with the transparent guy in front of you to give him the 10 green bars. With that now you unlock the door on your back for go outside with your own combat space ship.
7---Outside there is 3 different portals, I don't remember wich one is unlocked so just pass them all until you been teleported in to a combat. Beat this combat.
8---When you done go back to the open world respwan base and if you go on the village direction, really close to your base at the left side there is a lonely cabin with your same character. Speak with her a few times.
9---We are close now. Back to your combat space ship and the closer portal to you at your back should be unlocked now. Use it to be teleported to the market 31. In there just need to go downstairs until you pass 2 pink gates to find a sucubus behind a counter that will give you access to the bonification room.
And thats all, if somebody knows where is the save file I can share mine.
And also my apologies for my broken english.
