Frost Breathing
Shimo no Kokyū, Hiro Aganeya's breathing style: an original Breathing Style set in the Demon Slayer universe, planned with seven forms and a final form. Not playable yet.
Frost Breathing (Shimo no Kokyū) is the Breathing Style of Hiro Aganeya, the Frost Pillar. It is an original style, set in the Demon Slayer universe: where other styles strike like water, flame or lightning, this one does not strike. It settles. It will go hand in hand with the Nichirin of the Frost Pillar, whose blade already holds what it needs to show it.
What is planned
Frost Breathing will have seven forms and a final form, wielded with Hiro's Nichirin. Their names, effects, costs and keys are not set in the mod yet: they will be documented here as soon as a form becomes playable.
What is already in the mod
Several pieces of the style are already in place, with nothing to trigger them yet.
The blade's frost
The Nichirin hides 26 clusters of ice needles, folded into the blade while the breathing is inactive. Once it is, they will pierce the blade in fans, leaning toward the point, alternating on both flats and in a crest along the spine:
| Moment | What the frost does | Duration |
|---|---|---|
| Breathing starts | The clusters grow in a cascade, from the guard to the point | 0.7 s |
| Breathing held | They "breathe" in a loop | 2.4 s per cycle |
| Breathing ends | They shatter from the point back to the guard | 0.4 s |
At night, the needles glow like the blade's frost pattern.
The sounds
Three sounds are ready, with their subtitles:
| Subtitle | What you hear | Range |
|---|---|---|
| Frost Breathing | A deep, slow inhale through a nearly closed mouth: Total Concentration Breathing | 16 blocks |
| Frost flowers bloom | Frost flowers blooming and spreading across the ground, each one setting off others a little further out, then silence | 32 blocks |
| Air freezes | The air freezing in a ring: a crackle closing in around you, cracks, then the ring moving away | 24 blocks |
The spirit of the style
- Silence: Hiro's blade makes no sound as it moves. The breathing follows the same rule: air freezing, crystals forming, frost settling instead of striking.
- Frost that lingers: the Nichirin's cuts already leave a trail and crystals hanging in the air, and every hit freezes the target. See Nichirin of the Frost Pillar.
- No particles: like every AstroStuff effect, the breathing's effects will be drawn by the mod itself.
