I watched this work themed around the traditional event held annually at Shin-Nakano Technical College, an obstacle race where participants compete for time while being hindered by tentacles. There are a total of five obstacles: tentacle bread eating, tentacle quick escape, tentacle chair, tentacle reading, and tentacle pool. The rules are strict: a penalty of +1 second for leaking a sound, +2 seconds for leaking fluid, +3 seconds if a tentacle is inserted into the vagina or if the word "I'm coming" is uttered, and +10 seconds for sustaining an orgasm for 30 seconds. The tentacles crawling all over the body, the numerous suction-like tentacles, the狂暴 tentacles, and the tentacles attacking deep into the throat provoke the participants' reactions, affecting their finish times.

While the tentacle genre may vary in appeal depending on personal taste, I found this work to be flawless. Particularly, I purchased it primarily for Misono-chan and Azu-chan, with low expectations for the content, but I thoroughly enjoyed it. Occasionally, such works are a welcome change. Tentacle works are rare, and their mere existence holds charm, though mixing sports day elements into the play can be somewhat confusing in meaning. Some may hope for simpler tentacle assault works, but this piece offers an ultimate experience of enjoyment and climax. The tentacles are also hardworking and erotic, and it would have been great if the 30-second sustained orgasm scenes were featured for all participants.

The heated race for the number one spot, with the contestants' struggles and the tentacles' ferocity intertwining, captivates viewers. The tension and excitement over who will claim victory overflow from the screen. The diverse movements of the tentacles and the participants' reactions blend skillfully, creating new entertainment. This work is recommended not only for tentacle enthusiasts but also for viewers seeking fresh stimulation.
