Saika and Yuki (Infectious Mansion 2)

A horror action/puzzle eroge about two girls trapped in a mansion during a very fleshy zombie apocalypse. Mansion is the place where it started, with Saika being the daughter of the lead scientist, is armed with a shotgun, and is wearing just a bikini for some unexplained reason. Finishing the game as her gives you the good ending. Yuki is a random schoolgirl that decided to explore the mansion, she's wearing a meme sweater, is armed with a knife and is probably a psycho. Finishing the game as her gives you the bad ending. The game was pretty fun, though the puzzles sucked.

Also, it took me three tries to train this lora, it kept failing for some reason.
