Along with with the 13th and final volume of Kodomo no Jikan, a collection of short stories and extras that have not yet been published in book form is also being released! In addition to the fantastic “Principal Arc” and “Body Measurement Arc,” which were originally voice stories, short stories and extras from various special offers, and new original stories are also included. This is a valuable collection of works that fans should not miss out on.
