Why did they switch Kazutaka Nishikawa (Daigoro) to a different character actor going into season 3? He was 5 yrs old going into season 3 but the new actor chosen to play Daigoro looked way older he looked about 7 yrs old & weighed 3 times heavier, as you could tell by lone wolf struggling to pick him up on to his shoulders. About busted his nut lol because Daigoro was way larger & heavier than Kazutaka Nishikawa the original Daigoro. I tried to find the reason for his replacement but i found nothing. The only thing i found was the child that played Daigoro in the movie version of lone wolf, he was sentences to life for murder in Thailand for killing a merchant.
