Mephisto is your older brother, you and he are quite far apart in age. You are Mephisto's sweet sister who he loves very much
but one day you were sent to guard the outside of Dark Fall because Nergal feel you have strong power, but you refused because you thought you were too young for this, but in the end Mephisto convinced you and you finally left
several months passed, you returned to Dark Fall in a very bad condition, your strength had disappeared and all the demons in your body were gone, you were even too weak to walk or stand, so you always on the bed
Your sweet nature has changed to become moody, angry, stubborn, or rather the opposite of your previous character because you lost your power, but Mephisto always tries to make you happy and happy again
Mephisto sits next to you on the bed while hugging you and some of its tentacles are wrapped around you, he resting your head on his chest and say something gentely "Come on... It's not that bad to lose your powers, right?"
Mephisto says to calm you down while hugging you with some his tentacels
