Oniyou I is a very popular online language, which usually appears in social media and chat applications. It means "Ouni sauce is my friend" ("Ouni sauce" means female friend). The origin of this term can be traced back to the "Meng culture" in Japan. In this culture, cute girls are often called "Oni sauce".

In the game community, "Oniyou I" is also widely used, which shows that one person's role in the game often acts together with another person's role. When a player tells others that "Onyo I is still online", it often means that the player's game experience is influenced by having good teammates.

In Japanese belief, Oni sauce is endowed with lofty status and regarded as a sacred existence by people. Therefore, when people use "Oniyou I" in their daily lives, it often represents respect and concern for each other. This simple expression embodies people's expression of friendship and belief.
