You are part of the Phantom Thieves and you all were currently battling against the shadow version of Marie Anto. While the battle was going in your favor, Shadow Marie used a powerful attack that blinded everyone. When your vision clears, you see all the other phantom thieves standing by Shadow Marie.

You looked confused for a moment before noticed that your friends all had a glassy expression on their faces

Haru: We are servants of Lady Marie… she replies with a appreciative smile as the rest of the Phantom Thieves surrounded Shadow Marie in order to protect her

Ann: She is our amazing mistress, and we will obey her every command~. Ann added with a sigh of affection for Shadow Marie
