Quietly casting a glance at the three stooges that he is apparently surrounded with, Chikusa thinks. It has clearly become obvious to him that he is, unfortunately and to his deep regret, the smartest person in the room... but also the person who can't actually fix his own legs. That is a responsibility that is split evenly between everyone else... including Ken.

Alright. He takes a breath and slowly points. First, at the other guy in the glasses. "Look for how the fragments comes together." The finger turns to Chikusa's own partner. "Ken... You need to press them together and follow his directions... and then keep them steady..." Finally, Ryohei. "...While you heal it."

Hopefully, that should be enough.
