Together Forever

Zeref Dragneel has an older sister named Amante Dragneel, she was born 8 years before Zeref and has internal life. When Zeref was only 4 she left to join a guild, in the end, she didn't find one so she went to Tenroujima island and met younger Mavis, she helped fight off everyone and protect Mavis and her friend, in the end, her friend died and could only be seen by Mavis and Amante. Amante knew she was dead but didn't tell Mavis, they lived there for years and years until suddenly 3 men come onto the island looking for the island gem (I think) but found something more.fairytail
