At the Mountains of Friendship [v1.3]

Fighting!
Recruit magical girls to help contain the damage you’re doing to their reality. Sure it might make them go crazy, but what’s a few ruined lives compared to saving all of time and space? Saving it from you, but that’s not important.Friendship!
Form bonds between your girls to make them stronger in battle. Different pairings have different potential for how good friends they can become with each other, up to and including being lovers. Each girl has two others she can form a romantic bond with, sex scene included! With the power of friendship, anything is possible!

Fucking!
This first release has 40 sex scene CGs, with each girl having her own storyline about her descent into corruption. The more she fights and is exposed to your eldritch energy, the hornier she gets.

Fetishes!
Each girl has her own sexual theme and aesthetic. Build a team based on who works best together, or who you just want to see have sex. One may be more optimal, but the other might be more fun. Fetishes themes include bondage, femdom, free use, tentacles, cuckoldry, gangbang, and more!
