Zatch Bell! (2003 - 2006)

Kiyo's mind keeps returning to his first battle with Zatch as he continuously fails to dicipher the Red Book. He is amazed at Zatch's abilities, though that gets thrown aside when Zatch displays his wide variety of backpack outfits. As he returns to school with the little momodo, the team finds a guy with a momodo of his own, this one with the power to freeze anything, stealing a car from a hapless victim. Kiyo ignores the crime, marveling at both the ""kid"" and Blue Book while the guy gets away. The crook turns back up at the bank to hold it up while Susie is there for a withdrawal. At the same time, Zatch shoots off his mouth about Kiyo at school, almost getting them into trouble again. Kiyo ignores it and walks away. Along the way home, they catch a news report in a store window about the hold up. Kiyo instantly becomes torn between helping Susie and leaving the authorities to handle it. With nagging from Zatch, he finally decides to help her and, with Zatch along for the ride, powe

As the episode begins, Kiyo is once again paging through Zatch's spellbook, attempting to puzzle out the second spell, Rashield. But he has little luck, and soon abandons the task. When Zatch announces that he'll be accompanying Kiyo to school, the teenager is alarmed and yells at Zatch in an attempt to keep the Mamado from following him. Zatch does not take this well, and demands to know what he's supposed to do by himself. Kiyo, ever the genius, quickly whips up a small cardboard doll called the Voltron 3000 to keep Zatch occupied while he slips out to school. Though Zatch adores the toy, he follows Kiyo anyway, bringing the Volcan 300 along for the ride. Kiyo is annoyed to discover that because of the bank incident that occured the previous day, everyone is convinced he's some kind of freakish hero and therefore everyone stares at him and whispers about him behind his back. The teenager is further irritated when Zatch pops up, despite Kiyo's efforts to keep the lightning Mamado at h

After finding Zatch showing off his powers, Kiyo abandoned Zatch. Zatch found a lost dog on a bridge. Then, a strange girl named Sherrie and her weird mamodo, Brago, came to Kiyo's house.

When Zatch left, he saw a strange man in a cloak. When the man pulled out a book, and then the dog that Zatch found turned into a spiky monster.

After hearing Zatch scream, Kiyo ran downstairs, he paused and watched from the stairs. He runs down and pushes Zatch out of the way of an attack, which left a dent in the wall. Cheri asks Brago if it's another mamodo, already knowing the answer, he replies affirmative and asks what they should do. She tells him to let them beat each other up a bit. Downstairs, Zatch tells Kiyo that the dog is his friend; Kiyo tells Zatch that if it's so, he'd hate to see his enemies and sends a lightning attack at the charging monster after they cast another spell. When the man uses another spell, that sends sharp rocks out of the dogs back, Kiyo jumps in front of Zatch and takes the hit himself. Cheri decided to put an end to ‘these childish games' and intervened. Brago jumps down the stairs, landing directly in front the intruders with his palm out, ready. Cheri shouts the ‘Reis' spell, and the same ball that hit Kiyo knocked the dog out, turning it back to a puppy. Cheri tells the man to leave the

They follow Momon's directions and end up at Faudo's heart. Faudo's guardian of the heart reveals a room in the spinal cord that will give them a detailed map of Faudo's body.

The enemy Mamodo in the room are revealed to be Kardio, his partner Sauza, and Arth. Kardio aims an ice wave at the sleeping book keepers but is intercepted by Momon and Elle. Kiyo and Sunbeam awaken and they also join the battle against the pair.

Kiyo masters the demonic language in under an hour and searches for the hidden functions in the device. Elsewhere, Sunbeam asks why Sauza is working with Ellie and Arth and he reveals that seeing Ellie reminded him of his sister.

Riou takes control of Faudo and announces that those who serve under him will be spared from Faudo's wrath. Everyone obliges except for the team consisting of; Kiyo, Zatch, Megumi, Tia, Folgore, Kanchome, Sunbeam, Ponygon, Alishie, Riya, Ellie, Arth, Elle, Momon, Sauza, and Kardio. Kiyo reveals that they must survive for five minutes.

The team enter Faudo through his mouth with the help of Ponygon and Karudio. They follow a blood vessel to the spinal cord where they take an elevator and arrive in a room where multiple paths present themselves. The team then splits into two, Kiyo's team consists of Kiyo, Zatch, Li-en, Wonrei, Megumi, Tia, Alishie, and Riya while Arth's team consists of Arth, Ellie, Sauza, Kardio, Sunbeam, Ponygon, Folgore, Kanchome, Elle, and Momon. Elsewhere, Zeno and Dufort in an unknown location of Faudo's, watches the teams infiltration of Faudo.

Wonrei completely overwhelms Rodeux in battle and Rodeux realizes he must use Faudo's power to win against Wonrei. Elsewhere, Arth's team meets two Mamodo minions of Riou, Jedon and Fango. Sunbeam and Sauza volunteer to battle them which leads to argument between the two.

Ponygon and Kardio begin their battle against Jedon and Fango. Ponygon's and Kardio's attacks of fire and ice cancel each other out and they are quickly overwhelmed. Fango tells Riou to turn on Faudo's support system which encases the four Mamodo and their respective partners in a glass tube forcing them to battle. Elsewhere, Apollo and Dr. Riddles attempt to find a way to launch an unknown person into Faudo's mouth as he swims.

Kiyo's group continue on and run into Faudo's minions, the Mamodo Gyaron and his book owner Harry. Aleshie and Riya volunteer to battle them while allowing the others to rest and recover their energy.

Aleshie and Riya battle against Zarchim as he looks back at the time he recruited Aleshie and the embarrassment that he caused him.

Arth's team runs into Keith. Folgore manages to distract Keith to allow Arth and Ellie to continue on without being stopped. Folgore realizes Sunbeam and Sauzaa are out of energy to cast spells and tries to distract Keith while they recover before fighting.

Kiyo's team runs into Cherish and her partner Nicole. Ted tells the group to let him handle Cherish. Cherish reveals that Ted betrayed the kindness that her family gave to him. Ted reminisces about the kindness Cherish and her parents gave to him even though he was always getting in trouble. Cherish tells Ted she will defeat him in revenge for her parent's death.

Arth and Ellie reach the room before the control room where they are confronted by Riou. Riou uses a nearby control panel and seals the entrance to the room off so the rest of the team are not able to assist him. Elsewhere, Keith and Bari battle.

The team is able to overpower Riou. Riou tells his book owner Bankis to come out and fight. Bankis is revealed to have been hiding inside Riou and once out, tells them that the timing to cast spells will be easier now. As Riou overpowers the team, Dufort and Zeno arrive shortly after revealing they have burned Zarchim's book and prepare to battle Riou.

As the team thinks of a way to break through the door to the control room, Kiyo and Zatch are teleported inside. Zeno reveals he is Zatch's twin brother. Kiyo asks Dufort, now in control of Faudo, to stop Faudo or the world will be destroyed. Dufort replies he wants to see it destroyed as the current world holds no values.

Tia’s new spell "Chajir Seshirdon" blocks Zeno's attack, saving the group, but Megumi and Tia lose consciousness shortly after. Dufort asks Kiyo why he wants to protect a world which had shunned him for his ability. Kiyo asks Dufort why he does not know if he read his mind. Dufort replies he does not understand Kiyo's heart. They continue to battle and Zeno overwhelms them still.

"Bao Zakeruga" defeats Zeno and causes his book to burn. Before he disappears, Zeno destroys the gem which controls Faudo and tells Zatch if he deserves Bao, he should be able to stop Faudo. Kiyo teleports everyone out of Faudo excluding himself and Zatch using Faudo's system. As Japan nears Faudo's sight, Kiyo plans to use the teleportation device and teleport in front of Faudo and defeat him with "Bao Zakeruga.”
