On page 5 the first panel, wouldn't Taira's action considered as a foul since it looks like he is shoving his way? It also looks like he is pulling Indou but I can't say for sure...
@Inquisitionthere's no ref in this game so
In my eyes, it's considered a 50/50 cus' Indou is also looking like sticking his leg out to block Taira from getting the ball (while not getting outmuscled or some sort). Also usually if a defender is using just his upper body/arm to try to gain a positional advantage over the attacker without actively pushing/grabbing by force it's considered well within the limit.
