[@Sho Minazuki] [@Pikmin Eye]Hmmm...What if he and Rin trained together in Sheikah village? Like he just wandered in and asked to learn Nijitsu. Or or or maybe Rin's parents adopted him and so they're siblings :)  I'd think having a Deku ninja would be useful. Nobody would expect it, they could hide in flowers...It'd be rad.
