The Dark Mage's Regret

Sane

Mavis was always beside Zeref
He refused to let her go elsewhere without him
"Dont go anywhere, You're mine,Mavis..." He whispered as he took a proportion of her hair and twirled it. Around his fingers
Mavis couldnt do anything
All she wanted was Zeref to be happy
.....
Everyday Zeref would use mavis as a test subject
He'd implant dangerous things to her
But mavis didnt mind
Seeing Zeref so happy
She was inspired to be stronger for him
But her body wasnt strong enough
Zeref implanted a part of acnologia in mavis
And... She died of too much magic stuffed into her petite body
Only then did zeref regain his sanity
