Sora, a guy who was reading up on "That Time I was Reincarnated as a Slime", had not been paying attention when he got struck by a moving truck.
He was taking his final breaths and he said to himself "wouldn't it be cool if I was in one of those isekai things? I mean, I just got hit by a truck.
I would love to have some cool powers and be able to live how I wanted to live. I guess dragons are pretty cool and they can do whatever they want, but it would kinda suck to be a slime though".
After everything went black, he thought it was strange since he could move around, except he was trapped in a circular object. "Why can't I get out? Why do I feel lighter? and why do I have claws as hands!"
