good the last part, but the start felt super weird, like she was next to the POS, which was next to the lancers and archers, how did so many arrows came from above??, and in that case so close they should have both ended severely damaged by having the arrows sent so close aaaaand Scarlet had the time to at least stop the kid or punch the POS one more time. Position wise it weirds me out...
about the teacher at the end... well, I hope he also has a blessing of Chronos, probably not as strong as Scarlet but it could show some new techs for her.
