Tensou Sentai Goseiger: Epic on The Movie

A strange voice reaches Alata, steering him toward a hidden lead. He tracks down a mysterious girl who calls herself Rasil. Their initial encounter sets in motion a quest to uncover a powerful horn and the danger it poses.

Alata finds Rasil, the enigmatic girl who hints at a looming weapon. She reveals little and soon heads off toward locating the horn, leaving him behind. Before he can press the matter, Rasil vanishes as she departs.

Warstar remnants descend on Hokuto University in search of a meteorite sample. The Gosegers dash to the local museum to recover the remaining meteorite, only to learn Rasil has already claimed it. A clash erupts as factions collide around the museum corridors, heightening the danger.

Gyōten'ō and Deinbaruto ambush the group at the museum, grab Rasil's meteorite, and fuse it with their own. They summon the Horn of Ragnarok, a doomsday weapon capable of breaking worlds apart. The assailants slip away, leaving the heroes to pick up the pieces.

Rasil warns that the horn could destroy worlds. She flees again, determined to stop Warstar at any cost. Her warning becomes a personal vow that drives Alata to pursue a greater purpose.

Guided by Rasil's revelation, Alata pursues her and learns she is the sole survivor of an alien world obliterated by the horn. He resolves to stand against Warstar and defend Earth with his friends. This new sense of purpose strengthens the Goseigers' resolve to fight.

Buredoran leaves the Yuumajuu to rejoin Warstar and offers his power to Gyōten'ō and Deinbaruto. The betrayal signals a renewed threat against Earth as Warstar regroups. The alliance between enemies escalates the stakes for the protagonists.

Confronted by the Goseigers, Gyōten'ō unleashes the horn to summon eerie specters of fallen Warstar members. The apparitions harass and weaken the team, testing their durability and faith. The clash marks a turning point as the heroes endure and adapt.

The Gosei Knight arrives to aid the team, providing crucial support against the apparitions. Together they push back the specters and defeat Deinbaruto. The tide shifts in favor of the heroes as the stakes rise.

Gyōten'ō swallows the horn and commands Buredoran to enlarge him, delivering a brutal onslaught on their new mecha. The heroes struggle to withstand the overpowering assault as their defenses buckle. The battle reaches a critical moment that could decide Earth’s fate.

The Goseigers rally as Rasil lends them the power to summon a fresh machine, turning the tide long enough to challenge Gyōten'ō again. Her alliance with the heroes strengthens their chance to halt the horn's cataclysm. Hope returns as the team gains momentum against the horn's force.

With the horn neutralized again, Gyōten'ō is defeated and Buredoran retreats to rejoin Yuumajuu. Rasil thanks the Goseigers for their aid and departs to begin rebuilding her shattered world. Earth is spared for now, but the cost is high and the future remains uncertain.
