ガレガ is Dark Element， It's not a good idea to choose ソフィア as Tank
But I really don't have other choice

ガレガ will summon 2 Ghosts every 2' （8:00, 6:00...）

Our Kill Sequence Will Be
-> First Wave of Ghosts
->ガレガ

Though エミリー Made almost entire Damage
I think ラルミミ should be the MVP
She controlled ガレガ all the battle, and also controlled at least 2 Ghosts by the way

ソフィア should not always move a long distance, Because Ghost has ranged skills
But a short move is recommend ,
Yep for me , always Hit & Run~ , to reduce the damage and avoid skill
After 3 Ghost Killed All Damager should attack ガレガ
And then ソフィアちゃん take care of yourself please~
