Synopsis
"Wow, I can't go to my wife anymore!"

A high school student, Soma, who has moved to another world due to an "accident". As soon as I came to the untowered city of Ourantia, I encountered Omega, a Lamian girl who lost her tail and became a human figure.

Soma, who was blamed for taking responsibility, reluctantly formed a party with her and decided to live together as a [procurementist] who surpassed the glue in the quest. What's more, this Omega is a useless woman who has a habit of self-degradation, selfishness, and splurge.

Lamia without a tail, succubus that is not erotic, Banshee who does not cry, and friends who seem to have collapsed their identities.

And a mysterious parameter called [chaos value].

It's mostly your fault that my life in another world isn't familiar to you!
