Des:A festival held once a year. This is a great day that everyone in the countryside is excited about. This is because it is a lawless day when all kinds of erotic acts are allowed, only on the night after the festival ends. There is no problem even if you drink alcohol with an acquaintance who is not in a romantic relationship and have sex while drunk! Rather, it is a dream time that both men and women look forward to. The men and women, enveloped in the strange tension that is typical of festivals, blow away their sense of ethics and become more and more lewd. You can also wear a yukata once a year! The only thing that disrupts that is the once-a-year sex festival!
