You're Just a Tokusatsu Actor, So How Can You Really Turn into Tiga?

My name is Ye Zhen. I was reborn in a world full of monsters, but this world has no Ultraman. What?! What do you mean, I’m Ultraman Tiga?! “From now on, whenever someone believes Ultraman exists and believes in the light, you will gain one point of light energy. You can spend light energy to learn Ultraman’s skills, extend your transformation time, and increase your combat power.” Ye Zhen fell into deep thought. “Rule number one for Ultraman: never transform in front of people... How am I supposed to make anyone believe I’m Ultraman?!” “Huh? My actual job is an actor?” “I’ve decided to star in a tokusatsu series, and I suggest the director name this giant warrior who can fight monsters Ultraman!” My name is Motoya Matsusho, and I’m a director. Monsters pop up in this world every few days, and the defense force can barely keep up. But I’ve spotted a business opportunity in all this. That’s right! A giant warrior who can stand up to giant monsters! An actor named Ye Zhen suggested that I name this giant warrior Ultraman, saying it means ‘superhuman.’ That’s right: Ultraman, the fantasy warrior who defeats monsters! A real monster appeared on set, and the entire crew panicked. Only Ye Zhen charged toward it. “Dude, what the hell, Ye Zhen! Have you lost your mind? Run! Do you actually think you’re Ultraman?!” “Get a grip, you’re just an actor! You can’t take it on!” Ye Zhen: “Do you believe in the light?” Motoya Matsusho: “?” Ye Zhen: “Hyaa!”
