@CHICKIIES the escalation started when he got Isekai'ed... who wants to bet his summoning widened the rift and allowed the larger monsters to get in? Now... he forcefully Reverse-Isekai'ed himself... but he used "Dark magic". If there are no further escalations... despite him using dark magic... would that mean that the "Holy magic" that the saint uses causes damage to MC's world, but the "Dark magic" might fix the rift? Hmm
