Ana Lorena

Louise is terrible at magic, and can never use it the way she wants to. She is given the nickname "Louise the Zero" by her classmates, due to the inability to use any of the four common magic elements, whereby a mage's power is determined by the number of elements they can use ranging from a single element, one line, to four, square mage. Early in the school year, the second year students summon their familiars; this is considered a special ritual where a mage summons their eternal protector and partner, which usually is some sort of magical creature. Louise manages to summon a human commoner named Saito Hiraga, leaving her totally humiliated. Due to the sacredness of the ritual, Louise is left with no choice but to reluctantly accept Saito as her familiar. She proceeds to treat Saito as any other familiar only worse, making him sleep on a bed of hay and beats him with a whip for little to no reason, among other things.

One day Saito challenges a noble who disrespects commoners (Guiche) to a duel. Saito is beaten badly at first, but once a sword was put in Saito's hands, he gained a mysterious power and with this power he is able to defeat the noble in the duel. Louise and Saito's relationship's develop during the course of the story. Together they face many mysteries and uncover unexpected truths, including the nature of Saito's mysterious power, and the truth behind Louise's inability to cast magic.

EYESHIELD21

The plot of Eyeshield 21 revolves around a physically unassuming and non-assertive boy named Sena Kobayakawa who enters the high school of his choice, Deimon Private Senior High School, where his childhood friend Mamori Anezaki, one year older than Sena, already attends. His only remarkable physical abilities are his running speed, dodging techniques, and intense agility (perfect for football), the result of a school life spent complying with the demands of bullies. His abilities quickly catch the eye of the high school's American football team captain Yoichi Hiruma who forces Sena to join the team Deimon Devil Bats as the running back.

To protect his identity Sena is forced to publicly assume the role of team secretary, and enter the field wearing a helmet equipped with a green-tinted eyeshield in order to hide his features under the pseudonym of "Eyeshield 21." The makeshift team initially takes part in the Spring football tournament hoping to win with through the strength of their new "secret weapon." However, the extremely weak team is eliminated early on by the Ojo White Knights, a powerhouse football team that focuses on defense. Others see the skill of the current White Knights as having declined from the previous "Golden Generation," but the team members are trying to prove that they have the ability to surpass their predecessors. It is in this game that Sena meets the man he will acknowledge as his ultimate rival, Seijuro Shin, a talented linebacker.

After Deimon's defeat, the Spring tournament is revealed as a secondary in importance to the Fall tournament, where the teams compete for the chance to play in the "Christmas Bowl", the high school football league championship. Hiruma, Kurita and Sena regroup and slowly build a real team from other misfits and students looking to define themselves, such as Tarou Raimon, a baseball player who can only catch, the three HaHa brothers, and many others with the goal of reaching the championship. The series follows the building and growth of the Deimon Devil Bats and its members, as well as various rival teams encountered through their games and tournaments as they all strive to achieve their goal of playing in the Christmas Bowl.

ONE PIECE

A boy named Monkey D. Luffy, inspired by his childhood hero "Red-Haired" Shanks, sets out on a journey to find the legendary One Piece, to become the new Pirate King. To accomplish this, he must reach the end of the most deadly and dangerous ocean: The Grand Line.

Luffy captains the Straw Hat Pirates first through the sea of East Blue and then through the Grand Line. He follows the path of the deceased Pirate King, Gold Roger, from island to island on his way to the great treasure One Piece. On his way his crew grows to have a first mate, a navigator, a sniper, a cook, a doctor, an archaeologist, a shipwright, and a musician.

During the course of the story, the crew contend with both other less moral pirate crews and the Navy. The latter are the subordinates of the World Government, who apparently seek justice by ending the Great Age of Pirates. Many background story elements involve the delicate balance of power between the World Government and the world's most powerful pirate crews.

Claymore is set in a fictional world with medieval technology. Politically, it appears to consist of a large number of scattered, apparently independent, towns. In this world, humans coexist with creatures called Yoma sentient monsters that feed on human organs. The Yoma, being shapeshifters, are capable of taking on a human form and living in disguise amongst humans. By consuming a human's brain, Yoma can also absorb their memories, allowing them to disguise themselves as specific people without alerting even their close friends or family.

A nameless and highly secretive organization has created an order of superhuman warriors to protect humans from the Yoma. These warriors have come to be popularly known as Claymores, after the immense claymore they wield. Villages being attacked by Yoma hire Claymores to kill the Yoma for a large fee.

The story of Claymore follows the adventures of the Claymore warrior Clare. The plot follows her as she fights Yoma and struggles to hold on to her humanity. Starting in the 3rd volume, there is a flashback to her childhood on how she was 'adopted' by the Claymore Teresa. After Teresa rebels against the organization and is subsequently killed, Clare volunteers to become a Claymore using Teresa's flesh in order to take revenge on the Awakened who killed her. With determination and her human friend Raki by her side, Clare overcomes her low demonic power by honing the skills she inherited from Teresa, and other Claymores. As the series progresses, she becomes stronger and a better fighter, gradually earning the respect of strong allies and coming in conflict with the shadowy organization, the top Claymores who support them, and many powerful Awakened Beings.
