Are aliens invading again? Nope - it's just Ataru, Meno and Lum's mothers invading Parents' Day. But a language barrier may turn this meeting of the moms into pure mania.
The finalists have different motives. Lum wants Ataru's attention, Ran wants to get in Lum's way, Shinobu and Sakura want the money, and Ryunosuke has something to prove.
Surely Ataru wouldn't misuse bubble gum that has the power to create whatever he wants. But would that be worse than Lum losing the ability to speak other languages?
Two's company. Three's a crowd. And when a FOURTH party enters the Lum/Ataru/Shinobu situation? Things get pretty scary in Ataru's already complex love life.
