Yosuga is a Reason, a powerful inner philosophy that encompasses a set of natural laws, based on elitism and survival of the fittest, where only the chosen elite would possess the right to live. The useless and weak elements of society would be purged from the world, leaving only the powerful and strong. Power is acknowledged as being the only thing of true worth, and only the strongest of the strongest would have the right to rule. This Reason is most closely associated with the Chaos alignment of previous Shin Megami Tensei games.

A buzz word being used to refer to creators and influencers forming or encouraging unhealthy relationships with their fans. Usually used in the context of young audiences feeling they have a relationship with the influencer due to the huge amount of the influencer’s content they consume. The influencer in question, however, is unaware of the fan’s existence other than the general knowledge of having fans. Common examples include Dream and his stans. These relationships are exacerbated by the influencers confirming they have more than a creator-to-viewer relationship.

The word is circulating due to various YouTube essays about the phenomenon using the word, and therefore people who enjoy complaining about influencers repeating what they heard in the video in any comments section they can find.
