This is... very in-character for Hinoka. The training part that is. I wouldn't be surprised if those first two panels were actually part of a support conversation.
This looks like the beginning of some beautiful, fiery hatesex. Or just them trying to kill each other again. Which, if we're being completely honest, is probably the same thing at this point
Everyone else seems to have standard anime proportions, which are admittedly kind of inhuman to start with but acceptable, but Tomoko's looks huge for her body, like some kind of living bobble-head. Maybe because hers is the same size as everyone else's, more or less, but placed on a much smaller body.
