Uniqueness: Nothing really....
Synopsis: A otaku salesman got transmigrated to a fantasy world, with watching countless anime plots like that, and when God finally asked if he'd want something to request, he asked for bringing his phone hoping that the same should happen to him like some anime he watched. but reality threw something different but not really far but different. He wreaks havoc in the worlds with has apps.
Usual japanese mc's who have no ambition at all. Just like me, but reality force us to make an action. The synposis at webnovel is a lot more shorter not even 200 words...
