Hera Aetas

At a young age, Hera started hanging out with her brother, Two, and his group of friends [Akira Valerius, Fox, and Angel]. 

Due to being older than the bulk of the members of her group, she was able to start to get to know the mysterious boy War who shared class with her. They quickly dived into a very intimate relationship. Thanks to Hera, War was introduced to the group as well. 

She later became very close with Fox who was a mere perfect gentleman. This was going off and on while she was still unofficially with War which created War to then distance himself. 
Fox and her, thereafter, became a perfect couple. They had children but not much is known since they were protected and hidden away. 

Her closest friend is Incu. They began their friendship when Hera continiously visited the Ramen shop that Incu worked at when they were teenagers--the two would talk about everything there. She and Angel, helped integrate Incu into their group.
