Koyomi Morishita

Koyomi Morishita is a bumbling first-year high school student who is often mistaken for an elementary school student because of her small stature. She gets lousy grades and is not very athletic, so she decides to attend a magic school she saw in a flyer in order to change herself. Her unusual ability can turn any code, or spell, into a washbasin-summoning code, and this ability has gradually been improving.
