if ur talking about the shooter, she's one of the three battle sages of the western church who works for the five elders (rozzo family), who's also an otherworlder, the gun she uses is the only thing that get isekai-ed with her, her name is glenda attley
Thank you
When Diablo was running amok during that time the church was fighting Tempest, there were 3 battle sages. 1 of them got stuck fighting (more like being toyed) by Ranga, the other 2 were attacking Diablo.
That Glenda woman shot Diablo, saw that it was pathetically ineffective, yeet herself out of dodge so fast the remaining sage didn't even realize he was abandoned.
Who is she again?
