An obstacle race where participants compete for time while being hindered by tentacles, this is an annual traditional event held at Shin Nakano Technical High School. There are a total of five obstacles (Tentacle Food Eating/Tentacle Quick Draw/Tentacle Chair/Tentacle Reading/Tentacle Pool). The rules are: if you let out a sound → +1 second, if you release semen → +2 seconds, if tentacles are inserted into the vagina or the word 'orgasm' is uttered → +3 seconds, if you continue orgasming for 30 seconds → +10 seconds. Every time you react to the tentacles, penalties are added to your goal time… Tentacles crawling all over your body! Tentacles that suck onto you! Violent tentacles! Tentacles that assault you down to your throat! Who will claim the championship… The intense race for the number one spot begins now!
