Shi Dizai is an experimental fairy tale cartoon monster from alien, and its prototype is a dog (alien dog). Shi Diqi, translated from Shi Dizai by Hong Kong, is an alien "experiment No.626" (there were 625 experiments before).

　　Because it was created for evil purposes, the newly produced No.626 had a strong desire for destruction and was finally exiled by the Grand Councilwoman. Who knows that he destroyed the spaceship where he was held and finally escaped to the earth. In order to survive, he disguised himself as a stray dog and was adopted by a little Hawaiian girl named Liluo, who also got the name "Shi Diqi".

　　As a result, in the days when he got along with Liluo, he gradually understood what' Ohana' was, and his wildness gradually converged, showing his sincere and faithful side and becoming an important partner in Liluo's family. Deeply loved by children.
