One day, pervy high school student Madanbashi Kouichi finds himself pursued by a mysterious beauty and a gang of strange penguins. On top of that, a giant robot starts rampaging through town! Could Kouichi's Hi-ERO particles be the key to saving the city?

Unable to reproduce the original burst of Hi-ERO particles, Kouichi must discover the true power of Eros to defeat his new enemy, Antarctic Number 9!

A mysterious girl who loves penguins suddenly appears within the Penguin Empire. At the same time, Kouichi must become worthy to pilot Daimidaler.

The Penguin Empire finally succeed infusing a penguin with Hi-ERO particles and Kyoko meets a mysterious and handsome stranger with no memories.

A new robot, the Ritz Custom, appears after the Emperor discovers the secrets of Daimidaler. Will Kouichi be able to survive such a powerful foe?

With Kouichi out of the picture, a new main character arrives. The Penguin Empire has almost grasped complete victory. Now, Kiriko must fall in love.

Kiriko and Shouma must work together to take down Antarctic Number 11, but Shouma refuses to touch Kiriko anymore. He must find another way!

As Ritz and the others walk back to Penguin Castle, the Emperor continues testing the penguin particle device. Kiriko and Ritz face off, woman to woman!

While dreaming of Ritz's past, we find out how far her penguin family is willing to go for her. They must put the Super Antarctic to good use!

As Kyoko's eyes begin to open, Kiriko's most valuable possession is taken away. Kiriko unleashes an attack against Ritz and the city behind her.

Madanbashi Kouichi is back, and he's stronger than ever. Together, he and Kyoko are back in action, but what's the deal with Daimidaler's new upgrade?
