I Fell into the Ultraman World and Handcrafted All Kinds of Skill Cards

No Female Lead + Ultraman Fanfiction + Cards + Not Overpowered from the Start + Slice of Life

In an era when one in ten overworked employees died suddenly, Yinchuan was lucky enough to be that one. After dying suddenly, he ran into a transmigration wave and spent the next sixteen years as a lazy boy in a card-based world.

Then, on his sixteenth birthday, his own grandfather kicked him out: "Dear grandson, you're old enough to go out and make your way in the world. Grandpa looks forward to the day you become a legendary card maker~~"

Yinchuan hates trouble, so he has no intention of becoming a card maker. He just wants to laze around and waste his life.

But, well, things never go the way you want.

After setting out on his journey, Yinchuan transmigrates once more, arriving in a world with both monsters and Ultraman:

"Is this world's defense force a little too powerful? Aren't normal defense forces supposed to be useless background extras? Why does everyone have a Spacium Gun?"

Daichi Ozora: "What's with this boy from another world? How can he turn our skills into Skill Cards just by taking a few looks?"

X: "Oh, that's just how people from the data world are. You'll get used to it."

Zero: "What the heck? I only went for a stroll in another world, so how did my Ultimate Aegis get turned into a Skill Card?"

Max: "Thank goodness, I don't have a human host, so I can't use my ultimate technique, 'A Sword Beyond Worlds.' That means I didn't get turned into a Skill Card..."
