Zatch Bell!

A mysterious wind is stealing many things from everybody and everywhere, which is revealed to be a trick of Eido to easily gain whatever he wants without any effort, while Hyde wants to train instead, in order to unlock the second spell, but has to follow Eido's orders, under the menace of having his book burned. During one of his 'breaks', Eido sees Suzy and talks to her, but only to fail and she doesn't remember him. Zatch and Kiyo talk to her, and she then follows them. Angry about the life differences between he (Eido) and Kiyo, (and after being defeated by Zatch's second spell) he decides to kidnap some of the genius' friends and takes them to a water reservatory but forgot to tell Kiyo where they were. Inside the water reservatory, Eido tortures the students by almost making them fall to the ground while they're tied to each other. Thanks to Zatch's sensibility to feel the presence of sandwiches nearby, Kiyo managed to find them and fought the air duo, what leads to they learn the second spell: Jikirga. After a small clash of powers, Hyde and Eido escape, while Kiyo and Zatch take the hostages back. Then Eido deicides they're going to train and become stronger. (Source: Zatch Bell Wiki)
