Shen: King of Digimon
Previously Shen: King of the Mist
Considering the fact that Kiro picked up on a Kage signature technique (Lightning Armor) in the two weeks between the Prelims and Finals, it is just a case of Kiro being a prodigy. And even then, pretty sure every major OC could at least make him use his Sharingan in a fight if nothing else.
And as we'll see when we get back to Iwa, training is Tomiko's main thing. Gonna pick up a new skill to try and raise Tomiko to that desired level of "being average" among out cast and not bottom tier garbage XD
Well Tomiko still beat both Kilika and Taiyo at once
