After You is a Normal-type move. It makes the target move directly after the user (disregarding priority) and fails if the target has already moved. This is most useful in double battles with a slower ally.
As of 1.0.4, it can be taught by the Buff Move Tutor in Tsukinami Village Hotel for four Yellow Shards. Prior to 1.0.4, it could be taught by the Ultimate Move Tutor in Tsukinami Village at a cost of four of each shard.
