Ultraman: So What If I'm Human?

[No Female Lead, No Monster Girls, No Gender-Bending]

An ordinary person with no golden finger who transmigrates and has to save Earth is naturally doomed to die.

What kind of protagonist dies right at the start? Luckily, someone comes to the rescue.

But then they say that if he wants to grow stronger, he has to rely on himself, and promptly toss him into different universes to train.

He Yu: Is there really a chance I won't survive this?

Forget it. Since I'm here, I might as well make the best of it. Let's see what the first mission is.

Mission One: Meet Kai.

Uh-huh, easy.

Mission Two: Learn the Snake Heart Style sword technique.

What kind of System are you, good or bad?!

Don't laugh. You wouldn't get past the second trial either.

Jugglus Juggler: Without him, I would have gone down a different road long ago, one with no return.

Kai: The weight of a friend depends on whose heart they're in.

Asakura Riku (Geed): An older brother is family, whether or not you're related by blood.

Rosso, Blu, and Minato Saki: Heaven has already shown us mercy. Please show him mercy one more time.

Katsumi, Isami, and Asahi: As long as Big Brother's here, we can do anything without a problem!

Taiga: He's actually a pretty good guy. He's just kind of bad sometimes.

Tregear: Why does the light that shines on others turn toward me?

Protagonist He Yu: Damn it, why does every mission get harder than the last?! When can I finally go home?!

The bonds between these youths were forged the moment he transmigrated. As he saves them, is he not also saving himself?
