Capsule Boy

Tiny aliens from Degird measure 6.5 centimeters tall and arrive on Earth inside a spacecraft while pursuing fugitives. The ship changes into a capsule toy display near a toy shop, where a human boy unknowingly takes one of the aliens home, believing it to be a toy. The alien and the boy develop a friendship and work together to find a way back to Degird, while also dealing with a hostile alien force.
