In a one-shot featuring Kumagawa from Medaka Box, the narrative unfolds at Suisou Academy, just two months before Kumagawa's entrance into Hakoniwa Academy. This story delves into the events that culminate in the closure of Suisou. Noteworthy as the inaugural installment of the 'Good Loser Kumagawa' series, it first appeared in the Winter 2012 edition of Jump NEXT before being incorporated into Volume 15 of the Medaka Box series.
