An obstacle race where participants compete against time while being hindered by tentacles is a traditional event held every year at Shin-Nakano National College of Technology. There are a total of five obstacles (tentacle bread eating/tentacle quick draw/tentacle chair/tentacle reading/tentacle pool). The rule is that if you let your voice go out, → +1 second, if the water leaks → +2 seconds, if a tentacle is inserted into the vagina or if the word "Iku" is said →+3 seconds, if you keep going for 30 seconds → 10 seconds. Every time you react to a tentacle, a penalty is added to your goal time... Tentacles crawling all over your body! Numerous tentacles that suck you in! Violent tentacles! Tentacles that attack you deep in your throat! Who will be the winner... The heated race for number one begins now!
