Anya Melfissa

An ancient weapon known as “Keris,” she was granted human form through a mystical ritual performed by her master.
She’s just about always sleeping or playing games. Living mostly alone for so long has made her tend to be apathetic towards things and people she’s uninterested in, but when talking about things she likes, she can be quite childlike and passionate.
Her base personality is actually apathetic, especially towards humans. Don’t let looks fool you - that’s what every foolish human always does to themselves somehow.
