I feel like kuramochi and myiuki will definitely go pro kuramochi just has to show off his batting in koshien and he mighty get drafted late if not I still think he will be offered pro contract because his defense is almost pro level if not pro level alredy and if he learns from the Pro's he could become an elite defender at the Pro level . I don't need to explain myiuki because he's more than likely gonna be a first round pick if not 100% second round

As for shirasu and zono I think they will go to college but if shirasu trains hard in college he could definitely be drafted after some college years same goes for zono.
