Cerberus (Original Japanese Version)

Hiiro wants to get the Grand Trowa so that he can defeat the evil dragon, Dagon Zot. But first he has to find Nambuuko, the evil arms merchant who has it. And before he can do that, he needs to find a place to eat!

Young Hiiro meets a mysterious girl who comes out of the mouth of a dragon. At first he wants nothing to do with her, but then he realizes that he might be falling in love with this strange girl who picks pebbles out of the desert.

A trip to the local hot springs goes terribly wrong when the evil Sharisharu interrupts the vacation with a giant tentacled octopus. But her plans go awry when the octopus attacks her first!

On the way to the Land Where Wishes Die, the group is attacked by a massive bird. They seek shelter in a forest, but Sharisharu finds them and summons massive golems.

Hiiro is kidnapped by Nambuuko, who threatens to torture him until he reveals his connection to the evil dragon Dagan Zot. Can he escape?

Hiiro realizes that he possesses Dagan Zot's heart, and that if he dies, Dagan Zot will die as well. Only after Giruu reveals the depths of his devotion does Hiiro find the strength to carry on.

Sharisharu is ordered to kill Hiiro. She summons a shadow monsters to devour the townspeople and lure him into a trap. Can he use his new Dragon Form to stop her in time?

Hiiro struggles with his new Dragon Form. The last time he transformed, he attacked and badly wounded Giruu, and Saraato's magic can't help him. The only way to save him is to find the rare Serafuria herb, which is a half day's journey away.

Hiiro learns the magic spell of the Kokuu blade, a weapon which will strike an enemy from afar. Hiiro is far too terrible a swordsman to put it to use, but Master Theo notices that he has incredible power.

Hiiro is kidnapped by Sharisharu and Nambuuko, who want to control the evil dragon. Nambuuko reveals that he was the one who killed Hiiro's parents. But without his Dragon Form, can he defeat Nambuuko?

The party rushes to Nambuuko's floating castle to save Hiiro, but is trapped by an ancient artifact: The Sphere of Gyrokias. Can they escape this ancient trap in time to get to Hiiro and stop Nambuuko from creating a second tragedy of Balbagoa?

Nambuuko merges with the evil dragon, Dagan Zot, to form into a half-man, half-evil dragon hybrid. Can Hiiro use his dragon form to save Saraat and the continent of Kunaan?
