He was happy-go-lucky and originally wanted to live peacefully, but he accidentally ran into a huge trouble while taking a nap...
So, relying on sewer manhole covers, can he survive in another world until he returns home?
And what force brought him to this world?
"After forgetting everything, you still shine in my dreams."
