Guest was walking down the street, got hit by a Lamborghini, and was reincarnated into another world. Had it been an ordinary truck, Guest might have become a mere adventurer, but being hit by such a special car resulted in reincarnation as a special being: the God who grants skills to adventurers.

Today, another adventurer wishing to defeat the Demon King arrives at the altar seeking a skill. Give them a skill name to bestow upon them.

Everything else will work itself out.
