Shigeru Yahaba
Shigeru Yahaba is a rather calm and carefree guy but can be forceful when he needs to, such as when he lectured Kyoutani for missing practice. Kyoutani also comments on how he thought Yahaba was a ‘more shallow guy’ in which Yahaba agrees, and according to Kindaichi, he also seems to be a show-off (as seen when he throws a ball in front of Yachi so that she can notice him)
