Before the start of the game, they had first revived a bell-like mamodo with Animuto. As they're part of the actual mamodo battle, they fight Zatch, Kanchomé, Tia and Ponygon.
After that Biburio battled against Souma, who uses his Barudesu spell on them, after that Biburio gained a new spell Rigaro Animuku, that "transformed" them into manga books. Soon Nasuka "turned" Evil.
Part I[]
Nasuka appeared in the middle of the game, catching Kiyo's book, soon she was defeated by Zatch.
Biburio in the elapse of the game was using the Animuto spell to revive mamodo to fight Zatch. They do not fight directly but use the power of the mamodo to create enemies and bosses and send them to fight against the player's team.
In the game's climax, Zatch and Tia go to a library where they find Biburio. Then, he uses Birude Animuga on them. However, Souma (in Kokomelo's form) appears and burns Biburio's book, revealing that they were not the real villains and were only obeying Souma and Mitsuhiro's orders.
