I do not like the spread on page 18. The main focus is Wagatsuma sending Touga flying but that jacket beneath Wagatsuma's fist is throwing the composition out of whack. In a glance it look like he's being silly throwing a punch and a kick in the same time.
That aside, satisfying chapter. I guess Gaku's on his own now, Wagatsuma doesn't look like the type to go 2-on-1 when kanamori isn't bossing him around.
