A promo trailer for the 2011 OVA adaptation of Kodomo no Jikan, featuring "plenty of bathing suits", so lasciviously worn by the Kojikan lolis. This single-episode OVA is releasing in Japan this January 21, bundled with limited editions of the manga's 9th volume. The original manga is also known as Nymphet, and it's written and illustrated by female mangaka Kaworu Watashiya. This particular OVA covers the events from chapter 55 in the manga, where Daisuke's younger sister Chika appears for the first time.
