Togusa throws himself forwards, it feels like it takes all of his energy even though from the outside, it is just a lurching flop towards Tatsuo's hand. His grip on Tatsuo's forearm, though. That is where he finds his strength.

Isamu, for his part, can only look on the two men from a few steps away, twiddling his claws in a posture of worry.
