Top of the Class in the Land of Light: An Ultra Journey.

Lin Di traversed to the Ultraman universe, transforming into Diga Ultraman's brother, Dika Ultraman. Due to the frequent monster attacks on Earth, his brother Diga entrusted him to the original Ultraman to attend school in the Land of Light.

Becoming an Ultraman through a crossover? Why still need to go to school? On the verge of breaking down, Dika unlocked the All-Powerful Ultra System, which allows him to acquire a specific skill from any Ultraman he improves his rapport with.

Thus, he mingled in the Land of Light, fervently building rapport, evolving into an all-around Ultraman warrior.
