Alex is a student at the Royal Tennis Academy, who had trained to participate in the world championship tournament. A strange event happened, as a group of strangers came to the academy and defeated the best students, and showed their amazing skills in a single match. Alex felt this was an insult that he decided to find the masked person behind this group. He participated in tournaments for Junior, Senior, and surpassed most of the opponents, but the stranger still does not appear. There only one chance, when he passes the level of Varsity and proceeds to The Island Open tournament in the Mushroom kingdom.
