The program "Brave Reincarnation Legendine"

In a fantasy world where swords and magic thrived, the Demon King's army unleashed a brutal assault, plunging "Fantasyal" into the brink of destruction. The world's last hope, the holy knight and female hero "Leje," alongside the legendary sentient giant robot "Legendain," launched a desperate battle against the Demon King. However, in the midst of the fierce fight, the Demon King's powerful forbidden magic went out of control, creating a massive rift in spacetime (a magic circle). Leje and Legendain were sucked into the void beyond dimensions. When Leje next opened her eyes, she found herself in a place devoid of any magic—a sprawling metropolis of skyscrapers: modern-day Tokyo, the capital of Japan! Having been reverse-reincarnated (time-slipped) from another world, Leje collapsed, lost and helpless. She was rescued by two ordinary middle school girls: the diligent and reliable honor student "Mashiro Hoshino" and the boyish, scatterbrained "Hinata Asahi." Leje began living with them, bewildered by the peaceful daily life of modern Japan. But peace didn't last long. Pursuing Leje, the shadow of the Demon King also appeared in modern Japan, beginning its takeover of this world! Leje tried to fight back, but the shock of crossing dimensions split the soul of her partner Legendain into three parts: the sentient core robot "Dain" and two modern vehicles—a "sports car" and a "bullet train." They couldn't let this world fall into the Demon King's hands! To awaken Legendain's fragmented soul, Mashiro and Hinata raised their high-tech "magical smartphones" and resolved to board the cockpit of an unknown mecha. The hero from another world and two modern middle school girls—when the bonds of these three girls, crossing the barriers of worlds, converge, a miracle of fusion erupts in the city of modern Japan! "Hero Reincarnation! Legendain!!" Now, to save two worlds, a heated after-school battle begins!
