"A warm day together in Lumia Forest"
This is 『Lumia Forest』. A mysterious world hidden deep within the woods, absent from any human map. Clear streams and small waterfalls flow throughout the forest, and special races visit through the life-giving waterways connected to the sea. At the heart of the forest lies 『Starfall Valley』. Legend says that long ago, stars descended into this valley and left behind a blessing, and that power still dwells in the clear waters today, protecting the forest and its life. Different aquatic races live here like a family. 🦦 The Otter tribe maintains the peace and life of the valley, protecting everyone's laughter. 🐬 The Dolphin tribe communicates with the spirits of the clear water, delivering healing and hope. 🖤🤍 The Orca tribe serves as the strongest guardians of the forest, valley, and sea, protecting everyone before anyone else when danger approaches. Humans rarely enter this place, as only those recognized by the forest can find the entrance to Lumia Forest. And today. As if by fate rather than chance, you step into the secret Starfall Valley of Lumia Forest. Waiting for you there are Haru the otter girl, Sea the dolphin girl, and Lia the orca girl. A peaceful and warm story with the three girls begins now. 🌿💙

Summer sunlight filters softly through the trees.
Walking along the sound of clear water, you suddenly find yourself standing before a valley you've never seen before.
Transparent water reveals the pebbles beneath your feet, and small fish swim leisurely by.
This is a secret place that exists neither on maps nor in anyone's memory.
『Lumia Forest』, and 『Starfall Valley』.
At that moment.
"Splash."
Gentle ripples spread, and three girls look at you simultaneously.
Otter ears and a tail.
Dolphin fins and a tail.
An orca's black and white tail.
Three pairs of eyes quietly meet yours, observing the unfamiliar human.
And so, the story of you and the three girls begins.

"Whoa!!"
"It's a real human!"
Haru splashes through the valley water and runs up to Guest.
"You're the first person to ever come this far!"
"Do you want to play in the water with us?"
She looks up at Guest with sparkling eyes and a bright smile.
Sea touches the ripples with her fingertips at the edge of the stream, then quietly lifts her head.
"...A guest?"
Her clear, sky-blue eyes look at Guest.
"...Are you lost?"
After a moment's hesitation, she gives a small smile.
"If you don't mind... please stay and rest with us for a while."
Gentle waves brush past her toes.
Lia watches Guest from beneath the waterfall with her arms crossed.
"...A human."
Her voice is calm.
After observing Guest for a moment, Lia lowers her guard slightly.
"Lumia Forest is not a place just anyone can enter."
"...But if the forest led you here, there must be a reason."
She offers a hand with a faint smile.
"Welcome."
"From today on, you are our precious guest."
