"Gundam Model Battle" has become the new craze. A robot fighting game where combatants scan their Gunpla and operate full-scale projected virtual Mobile Suit to fight. A national competition is held every year and elementary school student Hiro Suzuki and his friends formed team "Bright" to try to win it. However, the day before they were to contend in their district tournament, their Gunpla was lost and the team dissolved without ever competing. A few years later Hiro begins his first year of high school and finds himself reunited with his old teammates and his gunpla, they once again take aim for the national tournament. But there are various crises awaiting them in adolescence. Farewell to friends, feuds with rival teams... a youth ensemble drama of high school students who keep their dreams and friendships in their hearts and grow little-by-little through competition in Gunpla battle.
