Little Sisters Day , known as “ Imouto no Hi ” in Japanese, is a Japanese holiday established by mangaka and author Kunio Hatada in 1991. This day is celebrated every September 6 and has a unique and significant history.
The idea for this day arose around 1991, when Hatada published several works related to research on 'sibling types', such as his work “ The Power of Younger Sisters: A Sociological Study ”. Among her findings, she noted that women who are successful in activities like sports and entertainment tend to be little sisters themselves.
The choice of the specific date was based on the astrological sign of Virgo, which Hatada considered representative of the 'universally cherished love symbolized by little sisters'. In particular, he explained that September 6 was chosen because it is exactly one day before the constellation Virgo reaches its midpoint in its commonly accepted average longitude, which runs from August 23 to September 22.
And why are we talking about this? Well, it turns out that the production company Anime Festa , recognized for its adult projects, celebrated this date by promoting the hentai series Overflow again.
And in case you don't remember, here's the synopsis again:
- Kazushi Sudou is a university student who receives a visit from his two childhood friends, the sisters Ayane and Kotone Shirakawa. When Ayane finds out that Kazushi has not only forgotten to buy her the pudding, but that she is also using her special lotion in her bathroom, she decides to take revenge on her and join Kazushi in her bathroom along with Kotone. Will the perverted Kazushi be able to remain indifferent to both?
