Arrow Manipulation in Slayers 2 is unlocked through the Arrow Orb, not by buying the art from the Skill Tree first. After you claim and use the orb, Arrow Core Training tracks four objectives before the technique is added to your inventory.
This guide covers the Demon/Muzan prerequisite, how to activate the orb, every training location and action, and the Skill Tree step that turns the reward into a usable fighting technique.
How to Get the Arrow Orb in Slayers 2
Start from the Demon route and make sure you can access the Muzan Evil Art roll. You can get an Arrow Orb from an eligible chest roll, or choose Arrow through the Muzan roll route when you become a Demon. If you need the broader prerequisite route first, see this Slayers 2 beginner progression guide.
Once you have the orb, claim it if it came from a chest, equip it on your hotbar, and use or crush it. That starts Arrow Core Training and should reveal the Arrow Core Training 0/4 tracker. The tracker is important because it shows which objective is active and confirms that the orb was activated.
The Arrow tracker lists the route as Meditate, Aim Training, Boulder Push, and Defeat Mizunotos 0/5. If your live in-game tracker displays a different order, follow the objectives on your screen.
Complete the Arrow Manipulation Training Tasks
The first two tasks use different training areas at Butterfly Estate. Finish each objective until the tracker marks it complete before moving to the next one.
Meditate at Butterfly Estate
Go to the Butterfly Estate training house and interact with the meditation mat. Use the Train prompt, then complete the moving-marker alignment minigame. Wait for the Meditate objective to register as complete before leaving the area.
Finish Aim Training at Butterfly Estate
Head to the archery area at Butterfly Estate and hit the targets. Keep going until the training progress or objective is complete, then check the tracker before moving on.
Complete Boulder Push beside Bamboo Grove
Travel to the area beside Bamboo Grove and interact with the boulder. Push it through the fenced route and reach the marked finish before the timer expires. You need to finish the route successfully for Boulder Push to count toward Arrow Core Training.
Defeat Five Mizunotos near Mistfall Harbor
For the final objective, go to Mistfall Harbor and look around the Shady Individual Rooyi area. Defeat five Mizunotos, then confirm that the tracker reaches 5/5. Once this objective is complete, all four Arrow Core Training tasks are finished.
How to Equip Arrow Manipulation and Unlock Its Skills
After the four objectives are complete, the Arrow Manipulation fighting technique is placed in your inventory. Equip it to your hotbar so you can use the art.
The unlock and the individual moves are separate steps: open the Skill Tree after equipping the technique and purchase the Arrow moves there. Completing Arrow Core Training gives you the art, but it does not automatically buy every Skill Tree move.
Yahari is not part of the four Core Training objectives, so you do not need to add that boss to this unlock route. Focus on the Arrow Orb and the four tasks above, then use the Skill Tree to finish setting up the technique.
