Funny enough it seems Taichi finally arriving will be to re-focus Arata, make him plays his strongest, nastiest, most stubborn and unapologetic karuta, who cares if maybe it will not be as elegant as his grandpas, or if he wins with moves his grandpa wouldn't make, he needs to grow out of that, his grandfather's mentorship was enough to get him to this point but he will need to break out of it to go beyond.
