Konosuba: God's Blessing on This Wonderful World!

Kazuma Satou lives a laughable and miserable life, being a shut-in NEET with no distinguishable qualities other than his addiction to video games. One day while on his way home, Kazuma dies as he attempts to save a girl from an oncoming truck—or so he believes. In reality, the "truck" was a slow-moving tractor, and he merely died from shock.

Now, he wakes up in limbo between death and heaven, where Kazuma finds himself in front of the arrogant goddess Aqua. Here he was given with two options: go to heaven or be sent to a fantasy world where his help is gladly needed to defeat the Demon King.
