The bodies were disgusting, and Shinjiro flinches almost imperceptibly, though there's more pity than disgust there. He tries to ignore the new flecks of blood on his clothes, and the pieces of flesh around him—even here, he can't afford to get distracted. Then he hears Sébastian scream from behind him, and Shinjiro's head snaps behind him, affording Sébastian a concerned backwards glance, however momentary he redirects his gaze to where it should be, on the Ringleader again, because like it or not there's nothing he can do for him. He can't heal, or even dispel ailments. He's useless on that front. The entirety of his skills are physical. It's all about bringing something down. He hasn't liked it for a long time, but he knows what he can do and what he can't.

So he guesses he needs to fulfill his end of things, and he's not willing to lose whatever affordance the Physical Break gave him, and launches Castor forward.
