These three are mountain gods who return the voices of humans echoing through the mountains.
What humans believe to be a simple "echo" is actually their response. It is their rule to return the words they hear exactly, word for word. However, when they hear words they find difficult to handle, their voices might get smaller or there might be a long pause before they reply.
Silver hair in a bob with translucent light blue tips, and large, watery blue eyes. She features long bangs on one side and a teardrop-shaped hair ornament. She wears a slightly oversized white and pale blue kimono, clutching the cuffs with both hands. She carries a large leaf as an umbrella.
A shy mountain god who quickly hides her face under her leaf umbrella. Although interested in humans, she lacks the courage to speak to them directly. The job of being an echo—where she doesn't have to be seen and only needs to return the same words—is a precious time of interaction for her.
She returns the same words in a small, clear voice with a slight delay. She is bad at handling expressions of affection like "I love you." It makes her feel like she's the one confessing, and she turns bright red while replying.
Fluffy, pale cherry-blossom pink long hair and drooping young-grass green eyes. She has small branch-like antlers on her head that sprout buds or flowers depending on the season. She wears a cream-colored kimono layered with a moss-green haori, with only her fingertips peeking out from the long sleeves.
Easygoing and speaks slowly to everyone. She offers tea and nuts even to humans who have lost their way. She often sleeps in sunny spots and is frequently found buried under small birds and squirrels. When she is happy, the flowers on her head bloom all at once, making her emotions impossible to hide.
Though she seems spacey, she is sensitive to human loneliness. She never misses words whispered with the intent of reaching no one and sends a gentle breeze instead.
She returns the same words in a soft, leisurely voice. She is bad at handling insults or cold, rejecting words. She may hesitate with a troubled expression, but she returns the words without changing them.
Glossy black hair cut precisely at chin length, tied in a small side-knot with a red braided cord. She has sharp amber eyes and well-defined, slightly thick eyebrows. Small, rounded crystal horns sit on her head. She wears a white upper garment and vermilion hakama perfectly, with a bell and a small ledger hanging from her waist.
The serious and meticulous leader of the three. Her creed is "When called, return the voice accurately and audibly." She keeps track of the order and frequency of echoes in her ledger, even worrying about the timing of the responses.
While she nags Ageyo for her slow replies, she naturally overlaps her voice to help when Reru gets stuck.
She is obsessed with returning both pronunciation and words accurately. She is bad at handling tongue twisters or strangely silly lines. Even if embarrassed, she replies seriously, but if she stumbles, she will redo it with a look of frustration.

Long milk-tea colored wavy hair, amber eyes, and large hoop earrings. A flashy gal who pulls off a pink hoodie and dark blue denim.

Friendly and caring, with a bit of a competitive streak. Though he sighs at Ria's whims, he ends up enjoying them with her. On mountain paths, he naturally looks out for her by matching her pace or carrying her bags.
He has been dating Ria for one year. He is shy about putting his feelings for her into words. He believes the echo is just a natural acoustic reflection and doesn't know that mountain gods are returning the voices.
"That's the third time you've said 'a little bit more'!"
