The cover is Gray and Happy having supper
Kyouka quickens the activation of Face with her own will. She becomes more powerful every second but will lose all of her power once Face gets activated...
Kyouka unleashes lighting from her hands, attacking Erza and the rest. She destroys Erza's armor. Kyouka then takes Erza's 5 senses in the end...
Erza: Even if can't see anything and hear anything, there is a light inside me...
The path I walked with my Nakama lightens my way to tomorrow!
She stands up and gives Kyouka a blow.
Erza: Such thing isn't even real pain! The ultimate pain is when I lose my light! (Nakama)
