Doraemon replaces Takopi. Can he turn everyone into healthy normal adults and fix the timeline?

Hailing from the 22nd Century, Robo-Cat Doraemon was sent back in time to take extra good care of his best friend...Shizuka!

Shizuka's life sure tough, but his trusty 4th Dimensional pocket is sure to have something to help her out...right?!

(No, Doraemon is not allowed to kill.)
