Zorori builds an alarm‑clock gadget to wake up just in time for free donuts. Yet when he remembers his mother and a single tear falls, strange things happen: flashes of scenes rush past and the ZZ emblem on his outfit vanishes! Zorori values it dearly, for his mother added it, though he never knows its significance.
After a crash‑landing on the street, Zorori, Ishishi and Noshishi are rescued by a fashion‑design student who turns out to be Zororene, their mother. The alarm‑clock gadget had turned into a time machine and hurled them back to the past. Together with Zorondo Ron, their father, they retrieve the device from both the police and a kaijuu.
