Ultraman: I Really Haven’t Been Secretly Trying Hard

Also known as: "You can all work hard as you please; I'll take care of becoming stronger!"

After transmigrating into a young Ultraman elementary school student from the Land of Light, he awakens a lying-flat victory system. As long as he invests in others, he can share all the 'results' of the effort they make during the investment period. Seis says this cheat is fantastic.

Zeta: "Seis, we promised we'd be academic failures together, so why are you secretly grinding into a top student? o(╥﹏╥)o"

Taiga: "Seis is too hardworking; he still comes to train with me in the middle of the night!"

Zero: "What?! Seis is my younger brother? And he's super studious?"

...

Seis: "You all misunderstand me. I really wasn't secretly working hard!"
