Explosive, flashy, and the only breathing style that makes you duel your own trainer to graduate: the full Sound Breathing guide for Slayers 2 — location, costs, forms and tier placement — plus the original Project Slayers route.
Sound Breathing is the showstopper style of Project Slayers 2. Built around the Sound Hashira Tengen Uzui's cleavers, bombs and wires, it plays like a trap-setter's kit: use the string forms to arrange the battlefield, then detonate everything at once. On tier lists it holds a comfortable A — slower to start than Thunder, but with some of the biggest payoff windows in the game once the setup lands.
It is also the only style with a graduation exam: the trainer himself fights you, and the win unlocks the kit. Bring your best gear to Iceveil Valley.
Materials, a mountain climb and a duel — Sound asks more questions than most trainers.
The standard breathing gate applies. Sound's materials push the real requirement higher in practice.
Beast Cores drop from beast-type enemies; Demon Horns from demons generally. Boss farming routes clear both lists fastest.
Head into the snowy region and start climbing. The Sound trainer waits on a high mountain ledge at the end of the route — stamina food and warm expectations both help.
Community reports place the fee between roughly 4,000 and 13,000 Wen depending on the patch. Codes on our codes page can cover the low end entirely.
Unlike most trainers, the Sound trainer fights you as the final test. Defeat him and the style unlocks. Come fed, healed and with your movement practiced.
Sound's kit follows Tengen's school from the anime: cleaver strikes, strings and explosives. Full form-by-form unlock order is shown in-game.
A concussive blast from the trainer's signature cleavers — the kit's opening statement and crowd-clearing baseline.
Wire-and-string techniques that zone, snare and set up detonations. These are what separate a good Sound player from a great one.
A sustained blade barrage — the style's main damage engine once the setup lands.
The finale: strings converge and the battlefield sings. Massive payoff damage on enemies caught in the arrangement.
If you are searching for Sound Breathing in Project Slayers (the original game), the route is completely different: the Sound Trainer taught from the peak of Sound Cave, and the style was gated behind roughly level 75 — one of the last breathing styles most players unlocked. Slayers 2 moved the trainer to Iceveil Valley, dropped the level gate to the standard 25, and converted part of the grind into the Beast Core and Demon Horn material costs.
Which game are you in? Sound Cave on your map means original Project Slayers; Iceveil Valley means Slayers 2. The two games' codes are separate too — both lists live on our codes page.
Reach level 25 on the slayer path, gather 3 Beast Cores and 10 Demon Horns, then find the Sound trainer on his high mountain ledge in the snowy Iceveil Valley region. After paying his Wen fee you must defeat him in a training duel — the win is what actually unlocks the style.
The Tengen-inspired Sound trainer waits on a high mountain ledge in Iceveil Valley. Travel through the snowy region and climb — the ledge is deliberately placed at the end of the route, so stock stamina food before the trip.
Community-reported costs are 3 Beast Cores, 10 Demon Horns and a Wen fee reported between roughly 4,000 and 13,000 depending on the patch. Exact numbers appear in the trainer's dialogue in-game — treat the range, not any single figure, as gospel.
Sound sits in A tier in most rankings. It trades fast combo starters for explosive, delayed payoffs: string and bomb-based moves that chunk health bars when they connect. Strong in organized PvP and bossing, less forgiving in chaotic solo play.
In the original game, the Sound Trainer taught from the peak of Sound Cave, with a much higher entry requirement (around level 75). Slayers 2 moved the trainer to Iceveil Valley, lowered the gate to the standard level 25, and added the Beast Core and Demon Horn material costs.
Uzui is the on-theme roll — the Sound Hashira's own clan, and an S-tier pick on the tier list in its own right. Beyond flavor, any S-tier clan amplifies Sound's explosive windows nicely.
