The Youngest Hides a Lot

In the middle of a blood-soaked battlefield, Rubian suddenly realizes — this is the world of the war novel “A Sword Planted on the Ruins!”

At this rate, the continent’s great hero, Duke Leviathan Zebert, is going to die, and the war that everyone thought was finally over will begin all over again.

“It’s bad enough that I’m rotting away on a battlefield — now I have to get a massacre ending too?!”

She wants to live. She’s done with war.

The only way to escape that doomed ending is simple: stick to this so-called “hero” like glue and make sure he doesn’t die.

So naturally…

“Hey mister, you wouldn’t happen to need a youngest kid at home, would you?”

I’ll stay by your side and protect you. So in return — please, save this world.

Somehow, things snowball, and Rubian ends up with a new family in the Duke’s household — while hiding quite a lot from all of them.

Her rather impressive title of “boy soldier-turned-mage who fled the Mage Kingdom” being one secret. And then, unintentionally… her gender too.

“None of that ‘Lord Duke’ nonsense — just call me Grandpa!”

“…Can a fairy become a little sibling too?”

A family that loves her without knowing any of her secrets. But somewhere along the way, a quiet fear begins to creep in.

“If they ever find out that everything about me was a lie — would they still love me the same way?”

The warmth that once tickled her heart — the first real affection she had ever known — now begins to sting.

“Could it be that Rubi is hiding something?”

No matter how much he hopes otherwise, the thought refuses to leave Leviathan’s mind.

This child has become someone precious to him — someone he now feels compelled to protect. But a shadow that he can’t quite put his finger on keeps creeping over Rubian.

My beloved gem, Rubi. Just what is it that you’re keeping from me?
