Japan has been invaded by aliens - but this is no ordinary assault. These extraterrestrials are cute and extremely dangerous. Their mind-blowing powers are way too much for the military. Enter Mao-chan, the daughter of a great general, and her charming best friends: Japan's only hope against this massive attack of the adorables!

Mao-chan is back, defending Japan from the most adorable aliens ever. The invaders are set on stealing Japan's most famous cultural artifacts and keeping them as souvenirs, but Mao-chan and her friends are determined not to let this happen - even when the aliens' leader appears for a final showdown.

Ginta Toramizu is a 14-year-old junior high schooler who doesn't have a lot going for him: he's near-sighted, doesn't do well in school, he's not good at sports, and to top it off, he's short! But Ginta is a dreamer and has had the same dream 102 times: it's always in the same fantasy world where he is a hero blessed with all the special abilities he lacks in real life. Then one day a mysterious figure appears at his school and summons him - to the world of his dreams!

The fate of Mar Heaven lies in the hands of Ginta and his fellow members of Team Mar when they must defeat the Phantom and his ruthless Zodiac chess pieces in the deadly War Games. The fifth battle is set in a desert field, and the first round pits Princess Snow of Team Mar against a powerful bishop class Zodiac. It's the perfect opportunity for Snow to try out her newest ARM!

The epic saga of the War Games continues! In the final match of the fifth battle, Nanashi for Team Mar is up against Galian of the Chess Pieces. There's quite a history between these two - Nanashi is the current leader of Luberia, and Galian just happens to be its former chief. Watch the sparks fly when these two lightning-wielders clash!

Could it actually be the beginning of the end? Princess Snow of Team Mar is captured by the Chess Pieces and taken to the ruthless Queen Diana. Despite being a member down, Team Mar must remain undaunted as they go into the final battle of the War Games. Will they be able to persevere against the Chess Pieces? And what fate awaits Snow in the hands of her evil stepmother Diana?!

The fate of Mar Heaven is on the line in the final showdown of the War Games! Ginta, the leader of Team Mar, must face the most powerful Zodiac Chess Piece of all, the villainous Phantom! Will justice prevail or will the tyranny of the Chess Pieces once again loom over the good people of Mar Heaven?!

Ginta and Team Mar have one final mission: to save Snow from the clutches of evil Queen Diana. The stakes get even higher when Diana announces her ultimate goal: the domination of Ginta's world after she takes over Mar Heaven. And Ginta is devastated when the identity of the Chess King is revealed - an opponent Ginta never imagined he would have to fight!

The battle against the Chess Pieces commences when the gang is enlisted by an ugly dog to rescue a princess who's been frozen in ice. Ginta soon discovers, though, "Princess Snow" happens to look exactly like Koyuki, the girl from school he's long had a crush on... Can he be a hero in the face of this frozen beauty?

During their much-deserved feast, Edward tells Ginta the story of a former Cross Guard leader - a man that actually defeated Phantom - but who has long since passed from this world. If Ginta and Jack hope to follow in this ancient hero's footsteps, they must become one with their weapons, and there's only one way to do that - to enter the Gate of Training.

While it's true that Ginta is having the time of his life in Mär Heaven, what's happening to those he left behind in the real world? With both her husband and now her son gone, Ginta’s mother is beside herself with grief. Can Ginta's friend Koyuki reassure her that her son is actually doing all right - and that fairytales really do exist?

Now that Ginta's team, known as "Mar," and the Cross Guard have successfully completed their preliminary tests of skill, the War Games officially commence. Of the six members of their party eligible to participate, Ginta is selected as Mar's team leader. This is no small undertaking, for on Ginta's capable shoulders now rests the very fate of Mar Heaven itself - if his team should fall, so too will the fate of the world.
