"ARTS that cost 3" is very vague.

If it costs or , Kosaki's effect cannot apply, since there is no   or    in the cost. You must use three cards to pay for the cost.

If it costs, then you can pay the cost with one Osaki and one other card.

If it costs, then you can pay the entire cost with one Osaki.
