Ultraman: My Teacher Is Hikari

As one of Earth's top researchers, Ling Lan never imagined that an experimental accident would send him to the Land of Light, where the patrolling Mebius would mistake him for an "unknown alien" and bring him back. By a twist of fate, he meets Hikari, the "god of science" in the Land of Light. With the [Hyperdimensional Intelligence System], Ling Lan sees the core flaws in Ultra technology at a glance. One theory about the "energy stability of Ultra Capsules" astonishes even Hikari, who has seen all kinds of cutting-edge technology, and earns Ling Lan an unprecedented offer to become his apprentice on the spot! From then on, the Science Bureau of the Land of Light has a "monster newcomer": While others train hard to master beam attacks, he hides in the lab building a "portable Plasma Spark Tower power bank"; When monsters invade, other Ultra Warriors charge straight into battle, while he pulls out a "Monster Stamina Reducer" and controls the battlefield with ease; Before Belial's attack, he develops a "regional energy barrier" in advance and hands out "enhancement capsules" to Mebius and the others. Using technology, he protects the Science Bureau and shocks the entire Land of Light! As his bond with Hikari deepens, Ling Lan's technological ambitions keep growing: Ultra Bracelets, biotech armor, deflection shields to counter "Absolute Destruction"... When the Kingdom of Absolut declares war and the Land of Light falls into crisis, Ling Lan stands beside Hikari and activates his ultimate invention: the "Universal Lifeform Energy Link System"! "Teacher, this time, let me protect the Land of Light!" This is the legendary story of a human apprentice who joins Hikari in sparking a technological revolution across the Ultra universe, growing from a novice into the "Land of Light's second blue brain"!
