Shef and Sakurako
Well, the girl's doing something but she's also stationary, so you put a manip round right into her chest. Hmm, so she's armored now, slower, tougher, not tough enough. You blow out both kneecaps as she approaches, slows her but they regenerate in short order. May wanna start making use of that manip round, slowed she might be, but she's still real damn fast and soon enough she'll be going for your throat.

Each spear is answered by an explosion, a detonating weapon launching you back further and further, another arrow loosing into your foes, the fire bolt visibly curving to strike them down. They do not cease in their pursuit, but you do not cease either. For once, you are no longer holding your ground, you are fleeing, you are firing back, and because of that, you are winning. Dayum, you could get used to this, is this what being Shef's like, just outranging your foes and gunning them down? It's not really on-brand for you but it seems pretty darn effective. The final arrow you loose is into the ceiling, blasting the scroll free into your hands. In it you find seven healing potions, you'll be needing two to heal your wounds, so you've basically got five. All the scroll says is to heal up and meet the master deeper inside.
The walk, it's the same as the one that took you in here, just with a different start and a different end, you find yourself on standing in the center of the lotus beneath the open sky, the boy standing opposite you. He regards your new appearance with all the expressiveness of a brick wall.
"I see that you are victorious, for what little victory matters here. Are you prepared for the next exercise?"
