__Unit:__ GAT-X105SEI Build Strike Gundam

A 7th-grader attending Seiho Academy. An only child, his family owns the shop Iori Models, and he's been a Gunpla fan from a young age. Both his building technique and his Gundam knowledge put many adults to shame. However, he's a poor Gunpla Battler with a long record of washing out in the first round.

It's confirmed that Sei is the creator of a customized GAT-X105 Strike Gundam model, the GAT-X105SEI Build Strike Gundam: A model focusing on mobility, it specializes in quick, hit-and-run attacks.



The story is set in the near future when GunPla Battles, competitions that pit Gundam plastic models against each other, have become popular worldwide in the "Second GunPla Boom." Sei Iori, a first-year middle-school student and the only son of a model shop owner, is talented at building GunPla, but inexperienced in the GunPla Battles. He encounters a mysterious boy named Reiji, who happens to be an accomplished Gundam Fighter. Together, they strive for the GunPla Battle world championships.
