In hell, the river pollution was as controversial as it was in the land of the living with its trash-ridden Sanzu River. There were particularly large number of items from coffins such as Rokumonsen (a ferriage fee for the crossing of Sanzu), eye glasses, wrist watches and the deceased's favorite items from their lifetime.

Koban, the writer for gossip magazine "Weekly Sanzu River", was sipping tea while looking back at his most recent scoop involving the secret meeting between Hakutaku and Peach Maki and the eye-watering birth documentary at Fukisho. Everything was going fine until he tried nosing his way into Enma Palace and ended up taking a picture of Datsueba's bathing scene. Koban however, was still in the mood for an even trashier gossip. Who might his next target be? Nasubi was on his holiday, carving a life-like sculpture of a frog from a tree branch but something was bothering him. When he consulted Karauri how he was lacking inspiration, he was advised to simply be himself. Shortly after, a Kingyosou drifting calmly in the wind caught his eye. As advised by Karauri, he decided to bend with the wind like the Kingyosou in front of him.

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!

While Hozuki was reading a book at Enma Palace's library, Shiro came by and began complaining how he discovered the Japanese folklore "Momotaro" that described Momotaro's dog as an Afghan Hound. Shiro's issue didn't end there as he had trouble reading the Japanese folklore "Inch-High Samurai" to the puppies. Hozuki was kind enough to lend him a hand but... Speaking of which, where is the Inch-High Samurai? The Yamagami (mountain god) "Princess Iwa" was upset as usual and threatened to kill any beautiful women who entered her mountain. Meanwhile at Enma Palace's lounge, Hozuki and Oko were eating together talking about the TV show "Woman's Quarrel Over Appearance" while the Tree Spirit was sighing over his current situation. Although Tree Spirits normally dwell in the mountain of the world of the living, he now takes refuge in hell due to his pollen allergy and the discord between the top 2 members of the Yamagami family, Princess Iwa and Princess Sakuya.
Hakutaku suffering from a hangover locked himself inside the toilet and prayed his pain to go away. Despite being used to seeing this kind of scenery, Momotaro was nonetheless disgusted with Hakutaku boozing himself and complained that it was no wonder why Hozuki looks down on him. However, when Momotaro mentioned how Hozuki would have the upper hand if he could hold his liquor well, Hakutaku got fired up and headed to Hozuki's place. Hakutaku and Momotaro decided to go along with the flow and joined Great King Enma's drinking party. Although King Enma intended to drink throughout the night, mentioning how it was a Japanese tradition, Hozuki quickly rejected the idea and allowed the rest of the Gokusotsu to go home before King Enma began boasting about his success story.

The Great King Enma suggested Shiro, Kakisuke and Rurio, who happened to be there at the spot should go wake him up but also warned how cranky Hozuki can get when someone disturbs his sleep. Despite Enma's warning, the three headed off to Hozuki's room. Momotaro was visiting Hozuki's office at Enma-cho to get his seal and made a fatal mistake by mentioning how Hozuki and Hakutaku looked alike. Hozuki was instantly infuriated by this remark and ran his backhand into the pillar behind him. Hozuki rubbed his wrist and matter-of-factly apologised. Soon after, the Great King Enma appeared out of the blue to explain how their discord came to be 1000 years ago.
