In Slayers 2 (Project Slayers 2), Wind Breathing is Sanemi Shinazugawa’s style and one of the costlier styles to obtain. There’s no way to purchase, spin for, or trade for it. Instead, gather a large supply of Demon Horns, travel north to a snowy area that drains your health while you remain there, and finish six training quests, ending with a duel.
Quick answer: Get to Level 25 and collect 50 Demon Horns. Then locate Wind Trainer Saneri on the snowy shelf beneath the Iceveil Valley path, finish all six of his training tasks, and defeat the Wind Trainee.
Wind Breathing requirements in Slayers 2
Level 25 is the requirement for every Breathing Style, with each trainer also demanding their own materials. Wind is among the most expensive options. At the same level, Flame costs 10 Demon Horns, while Serpent requires 20 Demon Horns and 5 Beast Cores.
| Requirement | Value |
|---|---|
| Level | 25 |
| Materials | 50 Demon Horns |
| Trainer | Wind Trainer Saneri (shown as Sanemi, Sanori or Seren in some builds) |
| Region | Iceveil Valley, the snow area past the bear region |

Sort a few things out before you leave the warm part of the map:
- Equip a katana. A Regular Katana or Fancy Katana from Raze’s Sword Shop both work.
- Unlock Wall Climb in the skill tree so the snowy mountain routes are less painful.
- Make Iceveil Settlement your spawn point; the valley’s cold continually damages you.
- Bring enough levels and skill points to handle snow enemies and beat the Wind Trainee.
- If you have another style already, reset Breathing through the Shop menu for 7 Ore.

Add to Google Preferences →Where to farm 50 Demon Horns
Demon-type enemies can drop Demon Horns, and Bamboo Grove’s cave is the quickest farming spot. Talk to Wagwan, repeatedly clear Hoyuzo Subordinates, and defeat Hoyuzo—the boss at the cave’s rear—between waves. High Demons in the snow around Iceveil also have a chance to drop horns, but cold damage steadily drains your health there, making this route slower in practice.
Count your horns before departing. If you reach the trainer with too few, the questline won’t be offered, and the trip back across the valley takes considerable time.
Wind Trainer Saneri location in Iceveil Valley
Saneri is positioned beneath the main snowy path, making him easy to miss if you stay on the route. You begin in Windy Peak’s starter highlands, beside quest giver Krue and the red torii gate. Start your journey there.




An entirely empty ledge likely means the area didn’t load correctly. Rejoin the server, and Saneri should appear.
The six Wind Breathing training tasks
Once you’re carrying 50 Demon Horns, speak with Saneri to begin the six-task Wind Breathing questline. If his dialogue won’t advance, you’re usually short on either the level or horn requirement; the conversation checks both.

How to confirm Wind Breathing unlocked
Check for the result in either of two ways: Wind Breathing appears as a skill-tree branch with Mountain Wind available to buy, and your equipped nichirin blade changes to green, the style’s color. Defeating the Wind Trainee also gives you a reward chest that may contain Fujiko’s Lantern or Kasumi Hakata, among other items.
You can check even sooner: if the training quest becomes your active objective as soon as you speak with Saneri, you met the requirements and the questline has started.
Wind Breathing skills and mastery costs
Kaze no kokyū—Wind Breathing—uses circular swordplay and sweeping gusts. Its forms are almost all offensive, unleashing whirlwind-like slashes that extend well beyond normal sword reach. Their broad range makes the cold journey worthwhile.
| Skill | Wind Mastery | Skill points |
|---|---|---|
| Mountain Wind | Unlock | 3 |
| Purifying Claws | 14 | 6 |
| Rising Dust Storm | 27 | 9 |
| Whirlwind Cutter | 40 | 12 |
| Idaten Typhoon | 53 | 15 |
Mastery increases only when a Wind Breathing ability lands a hit. Purchase Mountain Wind as soon as you can and use it to start fights. Hoyuzo Subordinates and Mother Bears are safer early targets; Kasugai Crow jobs, including the Reaper contract, provide a steady, ordered flow of enemies while your mastery bar fills.
Idaten Typhoon requires Mastery 53, 15 skill points, and a drop from the Sanemi boss, so mastery by itself won’t unlock it. The reward gives you its standard attack and a charged aerial slash shown with a full cutscene animation.
Farming the Sanemi boss for the Wind Katana
At Mistfall Harbor, Sanemi Shinazugawa is the best boss for Wind Mastery EXP and the sole source of the style’s signature gear. Expect to win multiple times; a 4x Luck boost increases the chance of rarer drops. His loot table contains the Legendary Wind Katana, the Wind Slayer Uniform, the Mythic Wind Haori, and the drop required for Idaten Typhoon.
Keep Windstorm Vigor Mode active and chain your forms rather than leaning on M1 strings. Each victory adds mastery and rolls another set of drops.
To recreate Sanemi’s full look, use the character menu to roll the Shinazugawa clan before entering the world. The clan is Mythic-tier, with passives including Marechi’s Blade and Windstorm Vigor Mode; these speed up early fights and Demon Horn farming. In customization, select swept white hair, add scars to the cheeks and forehead, choose the eye style, and equip the Demon Slayer uniform. The Wind Haori and Wind Slayer Uniform from later boss drops can be layered over this initial appearance.
Final Selection and the Demon Slayer title
Learning Wind Breathing does not grant the Demon Slayer title on its own. You earn that through Final Selection, entered via the gate after speaking with the guide sisters. During the trial, collect fruit for Rem, defeat five Lesser Demons for Vael, and retrieve Klien’s Nichirin Katana before treating him in the medical minigame.
The second half plays out in a dungeon. Defeat Lost Slayer in the underwater cave to grab the Submerged Key, clear the spike parkour, and flip the levers to reach Mizuto before the Hand Demon. Since he keeps calling in minions, open with Whirlwind Cutter or Rising Dust Storm to clear them, then save single-target burst for the boss. Winning grants the Mizunoto rank, the Demon Slayer Corps uniform, and a Kasugai Crow.
Once you hold that rank and carry the Wind Katana, the build is effectively complete. The only job left is farming mastery from the Sanemi boss until Idaten Typhoon appears at the bottom of the skill tree.
