This newly found team was suggested by Kamui Katsuragi as he is the one who decided to form an unlikely team. At first their teamwork was terrible, however, this changes over time. As the name goes by, TRY3 consists of three vanguard fighters, there are no relief players like previous seasons. Chrono appears to be its unofficial leader, working hard to make sure the team keeps its act together, as shown after their loss to Team Demise.
In GIRS Crisis, their goal is winning the G Quest. It is revealed by Misaki and Kamui that all of Team TRY3 will play a large role in defeating Ryuzu Myoujin, not just Chrono. To defeat their enemy all of Team TRY3 must become stronger, which will in turn give Chrono the strength to defeat him.
They win the "Ultimate Stage" of the G Quest and gain the right to join Ibuki's team to capture Ryuzu Myoujin. In Stride Gate, the new goal of the team is to fulfill their individual reasons to fight, as well as stop Ryuzu Myoujin and the Company's goal of gathering the 12 Zodiac Time Beasts in order to open a Stride Gate that connects Earth to Planet Cray.
After Cardfight!! Vanguard G: Stride Gate, but before the events of Cardfight!! Vanguard G: NEXT, the team was disbanded due to each member wanting to focus on their personal goals, and they all went their separate paths. All three of them enrolled into different high schools; Chrono is currently attending Tokyo Metropolitan Harumi High School, Shion was accepted into Fukuhara High School, and Tokoha went to study abroad in Paris. Due to their interest in the Under20 Championship, they each formed new teams.
- Before they came up with their official team name, a running gag was that when they went to an event and said that they haven't decided on a name yet the event officials would assume their name was "still undecided".
- The team's name is a pun to an English word "trinity", which refers to the three members being Dimensional Overstriders. In addition, their respective hair color bearing a resemblance to a traffic light, hence the team's official name.
