I just noticed, Rive is voiced by Makoto Furukawa who also voiced Saitama in one punch man and Rive’s unit God hand is said to have fists that can knock out deities just as saitama who beats his enemies with one punch. I don’t know if bushiroad did this on purpose or by just pure coincidence.
Bushi chose Takehito who voice Dio the narcissistic vampire with God complex to voice Kanzaki The guy who is also narcissistic and have superiority complex Nah I don't think any of these is a coincidence
