To usher in the new season, Letran and the other NCAA member schools performed the opening ceremonies at the Araneta Coliseum, followed by four basketball games on June 25, 2005. Other disciplines started their own tournaments within the following months, with beach volleyball as the last tournament on mid-March.
All of the games of the Colegio de San Juan de Letran Squires were forfeited when a certain player was caught playing in another league during the NCAA Basketball tournament. NCAA rules state that a player can't play in another league when the tournament is ongoing.
