But will she play?
In a Facebook post on Friday, the Crossovers shared a video of Santiago reunited with her teammates in a training session.
However, the club noted that she is only "sharing her professional knowledge and experience with the team during training" — casting doubt on the extent of her PVL return.
Prior to playing in Japan, she was named the conference and finals MVP in the Crossovers' first-ever title romp at the 2021 PVL Open Conference.
Santiago went on to win back-to-back Best Blocker and Fair Play honors in her last two years with Ageo Medics on top of the 2021 V.Cup title and 2020 V.League Division 1 bronze medal.
Meanwhile, talks have also emerged on the former PVL MVP's plans to become a Japanese citizen after her engagement to Japan national team deputy coach Taka Minowa in 2022.
Alongside Santiago's reunion with Chery Tiggo, the team will be naming five new players to boost their title bid in the upcoming PVL Invitational Conference.
