Kenja no Mago

Synopsis

The Knights and magicians start learning to fight together but the other Magician/Knight teams fail to get along. Shin feels guilty after learning that, having taught some of his spells to his study club, they will be forced to form a special team after graduation, under command of August, and will be supervised by the kingdom for the rest of their lives. However, the entire club is pleased since they view it as recognition of their abilities and a guaranteed career. Days later August tells them most of Blusfia has been destroyed and even more Demonoid's have been created from their population. Suspecting Schtrom is behind it Shin decides to put the club members through a training camp over summer break, with Sizilien offering use of a hot spring her family owns. Merlin and Melida insist on coming along as chaperones, not trusting boys and girls together without adult supervision. At the resort even Sizilien's family servants tease her about her future relationship with Shin. Merlin is happy to find Shin has made such excellent male friends. Melida amuses herself making the girls jealous about each other's breast sizes in the hot spring then declares she and Merlin are also going to train the club members to be as strong as possible.
