The manga actually starts really well. But it keeps relying on plot conveniences too much. Important information is not revealed to MC/viewers on purpose for "shock", but our MC despite being smart overlooks bizarre things in this world. Plot MC sacrificed by his father('s cult). MC wishes for a world without religion/god and gets transported into isekai village. all good for a while, until FMC and other villagers are forcefully being murdered in a "end of life" system by kingdom. MC tries fighting, and summons goddess Mitama sama (cult's god), who wipes the floor with the guards and successfully goes back to village. Mitama sama needs followersto store magical power and MC is trying to introduce her as a goddess while establishing a new religion.

Honestly speaking, the main problem is the lack of bare minimum curiosity from MC and the plot conveniently hiding crucial information. Hiding Information is not the same as "Mystery".

1. MC, despite seeing the public hanging (end of life ritual) in capital doesn't enquire more from fellow villagers.
2. MC sees the villager being discriminated in capital, but doesn't question WHY.
3. Goddess Mitama is omniscient (all-knowing) and yet doesn't tell MC the truth about this world until chapter 11. In fact, she apparently knows everything, and yet doesn't reveal basic stuff to MC.

The second problem is the rapid shifting of moods. The manga starts with comedy like cult sacrifice, becomes a relaxing comedy isekai during village arc, suddenly changes to serious mode (major character is hanged/dead) where MC almost dies, back to comedy again with our Goddess and suddenly shifts genres into sci-fi post-apocalyptic mystery battle royale at chapter 11. chapter 11 is a real turning point which makes the plot complexity explode and tbh, i just could not care at all :D about all the reveals/mysteries being setup.

Comedy is where this manga shines. If we ignore the forced "plot", we actually have a wonderful setting with Mitama-sama who is hilarious and MC trying to use his father's cult skills to establish a religion for our loli goddess.

The only character worth caring about is our useless Goddess Mitama. She is chaotic and her presence is the core hook of this manga. Imagine a loli version of Aqua from konosuba. MC is pro-active, but doesn't have much personality.

Overall
I would only recommend this if you can ignore the serious plot stuff. Honestly, just read until chapter 11 where we finally enter the main story. If you still don't like it, just drop this. I am only reading this for Mitama, and will continue reading until i run out of patience.
