Is there a way to survive getting minus of all stats every time the mc got raped, I don't want to have any black stains on the mc
either you can build up Rinko's mental states to a point which most encounters do little effect or using items to restore mental points.
typically teaching class will increase your mental stat by 5, as well as tutoring Ameyia at night. If your lust meter is full enough, you can masterbate and raise it by 5 or by 10 if you have the sex toy. Taking a shower when sweaty or covered in cum will increase it by 10. Renting and watching movies will also randomly increase your mental stats by 5, 10, or 15. The most obvious way to increase mental stat is preforming sexual act increasing it by 20
using items like reading magazines from the convience store, drinking beer, watching videos on the computer can replenish your mental stats, as well as resting inbetween sexual acts. If you managed to end the day in bed, you restore your mental point every night.
If you do get a black stains, they can be removed at the hospital with counceling, praying at the shrine behind the bus stop, or the hidden shrine down the river from the kiyomizu squad secret mountain base.
