Ultraman: The Prince from the Realm of Light

[Ultraman fanfiction + two male leads + couple: Zero + Armor Hero + original characters and Ultraman universe + nearly invincible]

(There will be Taiga and Titas, and Ace and Zoffy as couples. Kamen Riders will appear along the way. Since this is an original universe, there won't be any conflicts involving couples who love and fight each other. This story is going to be sweet!)

Yan Zemo had yet to become a full-fledged Heavenly Dao. Afraid to face his father, he left home, but ran into a spatial rift on the way and transmigrated from the Armor Hero world to the Ultraman universe.

Like a light, the next generation of Heavenly Dao. A lonely light met another light just as lonely as himself.

After losing his memories, Yan Zemo became unusually cheerful, far too lively for Zero's liking. Watching him tinker every day with research books Zero couldn't understand gave him a headache.

Could anyone really understand such incomprehensible stuff?

Yan Zemo: “Protective gear? I'll just make some for you! Why should you have to envy anyone else?”

Zero: [Tsundere] “I never said I had to have it, hmph. You... Though you went and made that decision for me without asking, well... thanks, I guess?”

“I'll work hard to win what you want. Since you aren't happy, let's create happiness together. There will always be hope.”

Yan Zemo: “Everything I do is because Zero deserves it.”

When his partner finally regained his memories and it was time to meet the family, Zero realized this was much more nerve-racking than meeting his own parents.

Zero: “Xiao Mo, you never told me your family members were all such big shots! Σ(￣ロ￣lll)”

Yan Zemo: “I forgot to mention it earlier ∠( ᐛ"∠)_”
