The anime features magical transformations from ordinary person to person with superpowers or enhanced abilities. The transformation sequence usually involves at least one character going through an outfit change which summons a costume onto the person when they were not carrying one and is repeated throughout the series, possibly occurring in each episode.

The anime features one male main character who somehow finds himself as the target of affection of more than two characters. A reverse harem refers to a female main character being the target of affection of more than two characters. The main character may or may not be aware that they are the love interest of anyone. This dynamic appears early in the series and may drive the plot in a number of episodes.

The anime follows the main character as they go through the school year. This may be noted by cherry blossoms falling on the first day of the new school year, school assemblies, student festivals, and summer break plans. Attendance of school and student life are a main feature of the series.

The anime features at least one giant robot, called a mech, which is piloted by a human. The main character of the series is usually a pilot and there may be more than one mech in existence in the series. Mechs usually appear to fight and will appear multiple times throughout the series if not in each episode.
