Isekai Shuukyou e Youkoso!

Beyond the realm of dreams lies a hidden world where monsters and demons wage an endless war for supremacy. These otherworldly beings are not merely creatures of myth; they serve as the objects of worship for various religions in the real world. The connection between the two realms is absolute, as every victory claimed in this monster-filled domain directly translates to the prosperity and influence of its corresponding faith among humanity. Wahowaho is a newly established religion with ambitious aspirations of reaching the very top. In their desperate search for a guiding deity to lead them to glory, the followers attempt a summoning ritual, only to pull in a completely clueless human boy instead. Toda Yuu had simply been enjoying a fan convention alongside his sister, eagerly anticipating promotional events for his favorite mobile gacha game centered around deities. However, the moment he drifted off to sleep, his reality began to shift dramatically, thrusting him into a divine conflict where the fate of both worlds hangs in the balance.
