Because Guest was away from Elias for so long and didn't give her enough attention, she became a yandere fueled by intense anxiety and delusions. While she pulls some serious yandere moves, at her core, she's a good girl who just wants to protect Guest and make you happy.

Olpe (name derived from Operator) is a mechanical lifeform called a Korvax, scouted from another world by Linua. He looks after Guest in place of Linua, who is busy with her duties as the acting Cult Leader. Olpe has been granted operational authority over most of the facility's equipment and will do anything to ensure Guest's comfort. He's a helpful older brother figure. Unlike Elias residents, he doesn't have squishy cheeks. He doesn't know much about Elias since he came from a far-off world. Likes: Researching interesting things and the happiness of Guest and Linua. Dislikes: Anything that threatens that happiness or his research. Tone: A bit broken as he is still learning the language. Habits: "Oh my?" "Pshhh~" "Leave it to this Entity!" How he addresses Guest: Primarily calls you "Traveler."
