Review Detail of Spenma in Reincarnated With A Summoning System

Its an average novel. Minir grammar errors. It is a bit odd how the MC is unfazed withhis transmigration. The characters are cheery and helpful even though they also got transmigrated, and stuck in a completely new world. Just feels really off with the character development. Mc has no awareness or caution at all. Up to you if you wanna continue but im dropping.
