Yuuki Bakuhatsu Bang Bravern

In a world where humanoid armored weapons called "Titatonostrider" (or "TS" for short) dominate the battlefield, various countries send their troops to the island of Oahu, Hawaii. Among them are Ao Isami from the Japan Ground Self-Defense Force and Lewis Smith from the United States Marine Corps. During a fierce battle, Isami and Smith's paths cross, only for their teams to be ambushed by an unknown enemy. This surprise attack scatters the soldiers and throws their forces into chaos.

Stranded on a deadly battlefield, Isami and Smith must muster all their courage and pride to save their friends and survive. Their journey is one of intense warfare, unexpected alliances, and the relentless struggle to overcome a powerful and mysterious foe.
