Transmigration is really tough ordeal. You never know what is awaiting you on the other side of summoning circle. There is bound to be misunderstanding, confusion, perhaps a certain amount of violence. Isekai, or an Otherworld, can be full of danger, it’s people might have too different beliefs and customs. They might be monsters or treat you as one.

It’s always full of surprises, both good and bad. Mostly bad.

Especially if the summoner is not "kidnapping" you to hire as the Hero..

but as the God.

With every single trouble that entails.
