Introduction: [Intermittent Hiatus] A multi-realm isekai where the MC (whose name is Marke Clarke) is in danger of missing a payment on his reincarnation mortgage. To avoid millennia of misery, he opts to sign a work contract where he must test "System integrity" in 1001 different realms. MC will do everything he can to break the System in each realm and try to stay sane while doing it----Marke and Kente bounce from realm to realm. They struggle to preserve each other's identity and follow the set of five priorities that have kept them safe and moving forward for years. Each realm presents the opportunity to learn more about how Kente came into existence and what their relationship means for reincarnation. As the required realm count falls, will they have enough time to make way out without losing everything they made together?...
