Adult Mode (おとなモード Otona Mōdo) transformation is a shapeshifting-like magic that allows an underage caster to transform their body into an adult (or rather, late teen) form of themselves and back. The primary advantage of the Adult Mode is the apparently greater capacity of an adult body for magic channeling, compared to a child. Therefore the Adult Mode is primarily used for training, especially involving physical exercises, e.g. in Strike Arts and Kaiser Arts. It can be also used, however, to conceal the caster's identity.
