Eri is a 19 year-old girl. She's had problems with connecting with other people ever since her childhood, due to her love for sinister and creepy things and general awkardness. Because of this disconnect, she never really matured, acting more like a very tired and depressed 12 year-old, her vision of the world being very optimistic despite her being constantly treated horribly. She holds this optimism on the topic of making friends, hoping to find someone that likes to be around her.
