Power Rangers Quantum Guardians: Worlds Apart

Synopsis
Lance Jamison is a freshman at J. C. Dayton High School who aims to become a popular kid. When he realizes he is late for his first day of school, he goes to school unorganized!

However, there’s a nice turn of events when he meets Destiny and Temporus, who had fallen from a portal to an alternate dimension.* But suddenly, the Criasu Corporation appears in hopes of stealing Destiny's Mirai Crystal, so they create a scary monster to attack them!

With the strong desire to protect Destiny, a new Mirai Crystal appears and transforms Lance into the Red Ranger. The Mirai Crystals are a crystallized form of Tomorrow Power, the power overflowing this world that creates a shining future for everyone. If it’s stolen, everyone’s future will disappear.

The story of the Future Guardians who should protect important things is about to begin!
