A nameless female mob unit in Blue Archive who serves as a part of Trinity General School's Justice Task Force. Despite her lack of distinctive characteristics she's managed to garner quite a following. For short she may be called 正実モブ (Seiji Mobu, "JTF Mob") or affectionately as モブちゃん (Mob-chan).
The named members of the Justice Task Force (with the exception of Koharu) share many character design elements in common with Mob-chan: black serafuku with red trim, long, straightblack hair and a red halo. The main feature that Mob-chan lacks is a pair of black wings. As a result, artists occasionally potray her to be a kind of "larval form" that the named members have "evolved" from, and that the growth of wings is an adolescent trait. As of Ichika's recent release, these mobs have red eyes.
