[Crossover] The World's Gardener

A long, long time ago, on an island at the end of the world with ten tons of gold buried beneath it, a girl met a cat with rabbit ears.

"Greetings, Lady Sixing. Is there a wish you'd like to come true?"

"Your world will be destroyed in ten minutes. Would you like to make a contract with me to save it?"

Sixing, rushing to pack up and flee: ...No contract, no deal. I never loved you.

QB: Didn't you say the origin-coordinate planet was incredibly important to Voyager, and that it would never be abandoned?!

Sixing: Avalon shared apartment. Stable space, surrounded by flowers, with a cute pet and free bedtime lullabies from a Grand-tier idol. The best choice for Voyager's origin-coordinate planet.

Merlin: Room and board included, plus bedtime lullabies!

A certain doctor: gazes enviously

QB: Is this the cutthroat competition between colleagues? Sign up and get a World Tree as a gift, sweetheart ^3^!

Sixing: Never mind, I'll protect my own planet instead. The black Rufu pollution from the neighboring planet is spreading too far, so I should deal with the source first. In short, I'm not becoming a Voyager. Merlin!

Merlin: ???

To keep her world from being contaminated by the black mud of the Holy Grail spilling over from other broken worlds, the lingering effects of curses, black Rufu, and all sorts of strange things, she also has to occasionally prevent Singularities from forming and history from being rewritten.

The girl becomes a gardener of worlds.

Sixing: "The easiest way to stop a world-ending threat, guide the world onto a stable path, and shape it into its most suitable form is to hold the world in the palm of your hand.

So the first step to saving the world is to take it into my hands!"

QB: Is this what a hardcore savior looks like? I'm in love.

The Fate series is heavily altered. The author flies whenever Hui gives them a nudge.

Record No. 1: The woman who still lingers in the minds of the Jujutsu world, the Kou Empire, Sindria, and the Reim Empire, and who is uniquely effective against Magi.

Theme: Love makes humanity stronger.
