“LittleSnow, night’s curtain is down—tell me how to change back!”

As dusk pooled like silver ink, Yue Liuyi rushed to LittleSnow, fingers kneading the silver-haired girl’s left hand like anxious moths at a lamp.

“Mm... does Little Yue really want the method?” Her voice fell like dew onto leaves.

“Of course! Being a tiny girl is a hassle, like steering a ship with toy oars.”

She’d wanted to open the Moon Post Bookstore, but at one meter twenty, she was a sapling under a shop’s tall lintel.

“Mm... before the method, there’s something else.” Her words unfolded like a letter under moonlight.

“Eh? What is it?” Curiosity pricked like a cat’s ears.

“Little Yue is the juvenile form of a World Tree Maiden. Your power isn’t mature. You shift between boy and girl by borrowing nature’s tide.”

“Na—nature’s force?” The phrase rustled like wind in leaves.

“Yes. The sun’s blaze turns you into a boy. The moon’s bowl of light makes you a cute girl. Ailuna and I let you break that frost-ringed limit. (I aced World Tree Maiden Studies; I shouldn’t be wrong.)”

“Eh!? Really...?” Surprise dropped like a pebble into a still pond.

She’d guessed in clouds of thought, but when it rained onto her skin, Yue Liuyi felt no ripple at all.

“So, by the same logic, pour other streams of nature in, and you’ll shift into other masks.”

“Like Eternal Tear’s effect?” The name gleamed like an icicle of light.

“Yes. Eternal Tear is the purest life-sap. Bathed in it, you can keep your true state. But wearing truth nonstop is a branch-heavy burden.”

“A burden? You mean life’s inconvenient when I’m tiny?” The thought sat like a stone in a shoe.

“No. Dreamwood Star’s life force is thin, a pale lantern in fog. It’s not fit for your health. Mm... didn’t you wonder why your magic lagged behind Breeze?”

“Yeah... I did.” The doubt knotted like a snagged thread.

Dixue’s words echoed a root-deep question—why her magic felt unlike a World Tree Maiden’s, until it brightened like a prism in Rainbow Sanctuary.

“Actually, that’s your self-regulation. Like a computer in sleep, you’ve got low-power mode. Girl form is the energy-saving state—solar by day, lunar by night. A green loop like a living wreath, low consumption.”

“Don’t make me sound like a battery!” Her protest sparked like flint.

“Hehe~ So how does Little Yue switch back? The answer’s a path lit by fireflies.”

“Eh? How? And no, I don’t have a one-click sleep button.” The imaginary button flashed like a red berry.

Yue Liuyi shook her head, a gourd rattle of refusal, fear misting cold around her ankles at Dixue’s next strange idea.

“My Little Yue’s smart; no button needed. Burn most of your mana at night, and you’ll slip back like tide to shore.”

“B-Burn mana...?” The word flared like a match in the dark.

“You haven’t noticed, have you? Right now, any spell you cast ripples the world like a stone in a lake.”

She froze; shock rolled under her skin like distant thunder.

Since turning tiny, panic had scattered her thoughts like startled birds, and she missed how her mana thickened like roots under soil.

“This is...!” Revelation rose like sunrise over a ridge.

No explosive storm—yet she felt her mana’s river bend to new banks, steady and sure.

It wrapped her like a gentle vine of life, sap breathing with her, no seam between self and stream.

“So much mana! Then... can I heal LittleSnow and Little Rose?” Hope fell like warm rain on wilted petals.

“Don’t use healing now. Your sea is too vast; you’ll flood the garden and over-heal us. It’s a rare tide—use nature magic.”

“Nature magic?” The words were moss-soft, cool and green.

“Mm... improve the environment. That’s roots-deep and long-lasting, like a spring that never dries.”

“How do I do it? Like you taught before—summon plants?” Seeds trembled like sleepers waking.

“Mm. Close your eyes first... then picture it.” Her lids folded like evening leaves, a landscape unfurling inside.

Dixue patted the blue-haired little girl’s head, a snowfall-light touch on a quiet grove.

Her voice flowed like moonlight on water, calm and clear, as she spoke an ancient spell like rings in old bark.
