Hatenkou Yugi

Rahzel and Alzeid are to meet Baroqueheat in a new city, but before he shows up Rahzel gets involved with saving a young boy named Vincent from some robbers, and then getting a run-in with his guard Soresta. Soresta was in the same military unit as Alzeid and Baroqueheat and thus knows them very well. Alzeid tells Rahzel not to use magic for at least three days so that she can learn to rely on herself, though Rahzel ups it to a week in frustration. During another run-in with Vincent's guards, Rahzel manages to get away with Vincent also causing a huge explosion, all without the use of magic. (Source: Wikipedia)
