The Circus!

(TW: Major character death, blood, maybe some eyestraining colors when chapters with art, and uhm. Gay people. /hj) Five friends are struggling financially. However, they find a circus that's hiring. They get jobs there and stay for a year, long enough to uncover the circus' terrible truth. They decide to quit and expose the truth to the world, but when they go through the House of Mirrors right in front of the exit, they're locked in with the circus magician, who announces that only one person can leave. They then decide to start a competition where each person dies after losing a game until only one remains. Realizing that four of them would have to sacrifice themselves, but for a greater cause, the five friends agree and begin to play. Anyways, it's not always a good idea to trust a stranger.
