The story begins at the herbal medicine store "Gokuraku Mangetsu" in Togenkyo. Hakutaku was explaining Momotaro the secrets of becoming popular around girls while making a medicinal hotpot. Around the same time at Hell's Enma palace, Hozuki was explaining the finer points of tortures in hell to Shiro and the gang while also making a special hotpot. While cooking, Hozuki realised that he was missing one important ingredient and decides to meet the gatekeeper who had them. At the public square, Gokusotsu all across Hell gathered for the "Gokusotsu Grand Sports Day". Nasubi was relaxed as usual but Karauri on the other hand was nervous. Female Gokusotsu like Oko were also present. Hakutaku and Momotaro arrived at the square and were greeted by Shiro, Kakisuke and Rurio. As part of the program, Kakisuke was to do a coordinated group gymnastics and Rurio a song with his seniors. Shiro was however not quite sure what to do. Soon, the fireworks calling for assembly was launched and The Great King Enma announced the beginning of the sports day! (thetvdb.com)
