A Mysterious Grand Prize from the Start: Venturing Alone into Another World

I got a chance to enter a raffle when I went shopping, and never expected to win the mysterious grand prize.

What skill did I get?

I transmigrated to another world, where I hunt monsters and rescue princesses.

I pulled the lever on the raffle machine.

"Oh! A rainbow-colored ball! That's the second time I've won one!"

"Huh? What's going on? There shouldn't be any rainbow-colored balls in this prize machine."

The staff member was astonished when I showed him the rainbow-colored ball.

"Sir, this is amazing!"

"Amazing? What did I win?"

"Your overall strength has increased 777 times!"
