To save Earth, unlucky Ataru must win a high-stakes game of tag against a beautiful alien. Luckily his friend Shinobu has offered a helping hand (in marriage) as motivation!

Lum is quite the handful, no matter what size she is. Later, a shapeshifting fox takes a liking to Shinobu.

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.

Asuka and Mendo go on a date and to say things don’t go as planned would be a vast understatement.

With the fate of the Earth on the line again, Lum and Ataru’s last game of tag begins.
