Kodomo no Jikan: Ni Gakki

Kodomo no Jikan: Ni Gakki was released in 2009 as an OVA continuation of the 2007 anime adaptation of Kaworu Watashi's manga series. Produced by studio diomedéa, this installment was created to build upon the controversial narrative established in the television series, focusing on the complex interpersonal dynamics between primary school teacher Daisuke Aoki and his student, Rin Kokonoe. The project served as a follow-up to the televised season, maintaining the studio's stylistic approach to the source material's exploration of emotional boundaries.

The character designs for the series were managed by Yoshihiro Nagamori, who aimed to preserve the distinct, expressive aesthetic of the original manga. The visual direction sought to balance the lighthearted school setting with the weight of the series' unconventional subject matter. Upon release, the series remained a polarizing entry in the animation landscape, frequently discussed for its challenging themes and the tonal shift between the animation's presentation and its narrative content.
