>>3500If you beat the sister (on top of the mountain) you get the bible of sex. Then go and get Maru, the kid that follows you around, and walk into the white light in your bedroom.
The trade chain is useless after you beat the boss besides the scenes that come with it.
Heres the trade chain (every scene requires Maru to be in your party):
The man next to apartment (Tooth-decaying candy)
The man in the right room on the second floor (first if you're a eurofag) of the apartment building (Suspicious Topical Cream)
The man to the south-east of the road to school (Mystery Toy)
The boy south of the mountain road (Beetle)
The man in the north-east corner of the station (Half-eaten Honey)
One of the three men with caps/coats that reside south of the road to school. (Treasure Map)
Google translate gave me weird shit for this one. (to take the circle to examine the front of the mountain road south of the well and 5 million yen and to obtain the "sexual ultimate bible".) Something having to do with the road to the mountain and having Maru with you.
After you obtain the "Ultimate Sex Bible" go back home and walk into the light in your room. I can't remember if you need Maru or not for this one.
Can someone give me a better translation of "マルを連れて山道南の井戸の前を調べると500万円と『性の究極バイブル』を入手する。"? I can't read nip.
