Codename: C

The tournament has reached its seventh period, and only one period now remains. Sei and Reiji have earned a good point score, and are working their way into the top group. Then the seventh period begins, with the announcement of a Gunpla Race. This is literally a speed race, where fighters compete for position during three laps of a special course constructed inside the arena. Sei's and Reiji's Star Build Strike uses its Discharge System to make an amazing starting dash. It looks like they'll finish the race in the lead, but Baker, the secretary of PPSE's Chairman Mashita, has prepared a huge trap in the special course. The Star Build Strike is headed for danger!
