Doraemon can be traced back to the deadline of 1969, when a kitten suddenly broke into the home of its owner, F. Fujio Fujiko. Although the deadline is almost up, the owner still plays with the kitten and catches lice for the kitten for hours at a time. When the master found that there was not enough time, it was too late to finish writing the manuscript. At this time, the teacher was so anxious that he suddenly kicked his daughter's tumbler toy. So the teacher had a brainwave and combined the image of a cat with a tumbler to create a Doraemon that brought us joy.

That is, the background of the seventies and eighties!
