Emiko stared at the woman before her — the axe still loose in her hand, her chest rising and falling with steady breaths.
"Mom…"
Her mother knelt, cupping Emiko's face in her free hand. Her eyes were no longer burning. They were warm. Tired. Human.
"I'm sorry you had to see that," she whispered. "I'm sorry I didn't come sooner."
Emiko shook her head, tears streaming. "Who… who are you? How did you—"
Her mother almost smiled. "My name is Mika," she said. "And I am still your mother. But I am also someone who made a promise — to protect you from the dark. Even if it meant becoming a little dark myself."
Emiko let the words settle — Mika, a little dark myself — and for the first time, she truly looked at her mother. Not as the woman who made her tea or brushed her hair, but as someone who had just killed.
"How long?" Emiko whispered.
Mika lowered the axe, resting the handle against the floor. "I suspected Riku for years. Small things. The way he looked at you when he thought I wasn't watching. The prayers that weren't really prayers." Her jaw tightened. "But I never had proof. Not until… him."
"Him?"
"The one with the rainbow eyes. Riku called him Douma."
The name meant nothing to Emiko. It was just a sound — strange, cold, like something whispered in a language she wasn't supposed to understand.
"Who is he?" she asked.
Mika's expression darkened. "I don't know exactly. But I've heard rumors. Stories passed between people who've seen things they shouldn't have. They speak of beings that wear human faces but aren't human at all. Demons, some call them. Others say they're fallen bodhisattvas — corrupted by something older than memory." She paused. "The government doesn't acknowledge them. Officially, they don't exist."
"But they do exist."
"They do." Mika reached out, tucking a strand of hair behind Emiko's ear. "And there are those who fight them. They're not soldiers. Not samurai. Just… people who learned to breathe differently. To move differently. To kill what shouldn't exist."
"Have you ever seen one?"
"No. But I've heard enough to know Riku was trying to become something like them. And that creature — Douma — he was already there."
Emiko's hands were trembling. "Teach me. Whatever you know. However you learned."
Mika's eyes met hers. "Are you sure?"
"I don't want to be helpless anymore."
A long pause. Then Mika nodded.
"There is a breathing style called Water Breathing. It's not something the government teaches. It's not written in any book. But the rumors say it's the most effective against demons — the way water adapts, endures, flows around any obstacle." She stood, offering Emiko her hand. "I will teach you what I know. But Emiko… this path is not gentle. Once you start, you cannot unsee what you have seen tonight."
Emiko took her mother's hand.
"I already can't unsee it."

That night, beneath a ceiling of stars visible through the broken shrine roof, Mika guided Emiko through her first breath.
"Inhale like the tide coming in. Hold. Then release like water over stone."
Emiko tried. Failed. Tried again.
And again.
By dawn, she could feel something stirring in her chest — not power, not yet. Just the whisper of possibility.
But when Mika finally slept, exhausted beside her, Emiko closed her eyes and breathed differently.
Deeper. Slower.
As if the universe itself was drawing breath through her lungs.
She didn't tell her mother. Not yet.
It felt too strange — too personal.
And after everything, Mika had already given her so much to carry.
