Background The concept of "sister teams", teams owned by the same company or under the same umbrella, aren't relatively new in Philippine sports. The
Philippine Basketball Association has three teams owned by
San Miguel Corporation and another three owned by the
Manuel V. Pangilinan group, the former of which includes the
Manila Clasico rivalry between the
Barangay Ginebra San Miguel and
Magnolia Hotshots.
Rebisco's first volleyball team, the
Creamline Cool Smashers, joined the
Premier Volleyball League in 2017 while its second team, the
Choco Mucho Flying Titans, was established two years later in 2019, forming the league's first sister teams.
2022: Large crowd turnouts In the
2022 Open Conference saw both Rebisco teams meet in the final round for the first time, with them meeting in the semifinals. On April 3, 2022, with the country easing from the
COVID-19 pandemic, the second games of the semifinals drew a crowd of 16,687. The first game of the doubleheader saw Creamline complete a two-game sweep of Choco Mucho to advance to the finals. The large attendance turnout would continue throughout the year, with the teams' matches in the succeeding
Invitational and
Reinforced conferences recording attendances of 15,237 and 19,117, respectively, with the latter surpassing the aforementioned 2022 Open Conference record.
2023–2024: Championship clashes and a new attendance record In the
2023 Second All-Filipino Conference, the two teams met in the championship for the first time. On December 16, 2023, game 2 of the championship saw a crowd of 24,459 watch as Creamline complete a two-game sweep of Choco Mucho to win their seventh league title. The game broke the Philippine volleyball attendance record previously set in the
UAAP Season 78 women's volleyball finals in 2016, which featured
rivals Ateneo and
La Salle. Players and coaches on both sides expressed their gratitude towards the record crowd as well as mentioning the overall growth of volleyball in the country. On April 30, 2024, at the start of the
All-Filipino Conference semifinals, Choco Mucho would finally get their first victory over Creamline in their thirteenth match-up. This preceded their championship rematch which saw another Creamline sweep with them winning their eighth league title and second against Choco Mucho. == Records by season and conference ==
