The units I used for this battle are Liter, Blanc, Ludmilla: Winter Owner, Noir and Modernia. The team's Skill levels and equipment are shown before the fight begins in this video. I recommend using team for survivability, damage output, and the fact that this boss is weak against Water. Just be careful not to be hit from Chatterbox's attacks, otherwise you'll be affected with a Defense debuff which is stackable. Best of luck and thanks for watching.
