|Nexus of Serenity|
|Series of Origin||Shadowverse|
Nexus is the very first keeper introduced in the game, the keeper of harmony. She is also the first character who's leader can be earned through the story mode, specifically on Chapter 12 of The Morning Star: Conclusion. She is currently using Losaria's body as a host.
Nexus has very formal speaking patterns when she speaks. She seems to have no regard towards the emotions of others, and is instead very focused on her own and bringing "harmony" to all dimensions.
