After seemingly defeating a tough Nejire Beast, the Megaranger are pursued by a strange man who suspects a greater problem with their recent battle.
Kenta Date, a game-playing high schooler, is recruited alongside four other students to unexpectedly become the Megaranger due to the pre-emptive start of an invasion from the dimension of Neziregia.
After barely escaping from Neziregia to I.N.E.T.'s space headquarters, Kenta rashly returns to Earth to deal with them personally.

Kenta confronts Shun about putting his needs over the team's when he chooses to do extra studies over his Megaranger duties.
