Slayers 2 Demon Horns: where to farm them
Plenty of ordinary demons drop them. The Archives screen lists 6 enemies, every one at 50%, and a boss called Hoyuzo drops 3 at a time. The best farm is a cave full of weak demons near the Mother Bear.

Archives, with Demon Horns open: Uncommon, then under Source: 50% (Blood Hounded Demon), 50% (Greater Demon), 50% (High Demon), 50% (Hoyuzo), 50% (Hoyuzo Subordinate), 50% (Lesser Demon).

At 50%, a horn takes two kills on average. Hoyuzo averages 1.5 horns a kill, three times a normal demon.
The cave by the Mother Bear
- Head for the Mother Bear in the bear area, the same stretch you cross for Tom’s bear quest. The best horn spot is right under where she stands.
- Drop down to the cave underneath the waterfall by that platform.
- Fight the demons inside. They spawn about six at a time, so two or three players make it easier. They are labelled
Hoyuzo Subordinate, and horns can drop as they die. - Expect company. Other players in public servers get in the way here.

The same spot: the enemy under attack is labelled Hoyuzo Subordinate.

A dark area; the minimap labels include Mother Bear and Shrine. At the player's feet, a pickup reads Demon Horns; along the top, +66 Exp, +30 Wen and +8 Reputation.
Hoyuzo and the level 40 quest
Hoyuzo, The Sickle Reaper, is the boss of the same demons. His bar shows 1,445 health, a Rare Chest, and Demon Horns x3 (50%). He also drops Sickles at 7% (3% on the earliest build; marked Lvl. 52), his top and bottom at 3% each, and a 10% skill, Scyther Vortex, struck through until you own Sickles. His fight tips are on the Hoyuzo page.
There is a quest on these demons too. An NPC named Wagwan stands by the waterfall with Clear Hoyuzo’s Guard, four guards to defeat, for 720 experience and 324 Wen. It opens at level 40; wait until then and you collect horns and the quest reward from the same kills.
The other bosses and their drop lists are on the bosses page.

The Sickle Reaper Hoyuzo, 1445 / 1445, Rare Chest. Under the bar: Exp +360, Wen +160, Demon Horns x3 (50%), a struck-through Scyther Vortex x1 (10%) marked Missing Sickles, and Sickles x1 (3%) marked Lvl. 52. This is the earliest build seen; later bars read 7%.

Beside a waterfall, an NPC labelled Wagwan. The tracker on the left reads Clear Hoyuzo's Guard 0/1, Guards defeated 0/4, Exp +720, Wen +324.
How many horns each trainer wants
Longest bar first. At 50% a kill, each horn takes about two kills.
- Wind · Saneri50 horns (about 100 kills)
- Water · Urokodaki30 horns (about 60 kills), or none
- Serpent · Obari20 horns (about 40 kills), or none
- Insect · Shinora15 horns (about 30 kills)
- Flame · Rengu10 horns (about 20 kills), may differ
- Thunder · Zentaro10 horns (about 20 kills)
- Sound · Tengai10 horns (about 20 kills)
- Stone · Gyoreino horns
For Wind, bring 50: Saneri asks You need 50 Demon Horns for this Quest!, even if you see 30 quoted. Sound may take Beast Cores instead of horns. Stone asks for cores and no horns; the Beast Cores page has a tally that adds horns and cores together for any set of styles.
Other things that cost horns
Trainers and Alchemist Meku both trade in them, and Kazuma needs you to hold 12 before he will teach Soryu (see the Soryu Trial). Beyond the breathing trainers, Alchemist Meku’s shelf at Mistfall Harbor prices his elixirs and potion in Wen plus Demon Horns (every drink is on the elixirs page):
- Health Elixirs, 350 Wen and 2 horns each. The level 100 supply quest wants 25 of them, which is 50 horns. The fishing bait quest wants 30 elixirs of three kinds, another 60 horns (see fishing).
- A potion for the Tai Chi trainee fight. Meku’s shelf at the docks has an Underwater Breathing Potion at 600 Wen and 6 horns, reportedly the one you need for that fight.
The level 40 quest is one stop on a longer route; levelling to 225 shows where the horn cave fits among the other level bands.
