In Devil Hunters / Chainsaw Man Devil’s Heart , you get the Chainsaw/Devil Heart by either finding a spawn or doing Ito’s quest. The most direct method is the quest: collect 10 bullets, then talk to Ito again to receive a free Devil’s Heart.

Ways to get it

  • Random spawn: a Devil’s Heart can appear at a random spot on the map every 30 minutes, with a 50% chance to spawn.
  • Quest reward: talk to Ito , take the quest, and bring him 10 bullets ; after that, he gives you a Devil’s Heart.
  • Tracking help: if you have the Devil Heart Notifier gamepass, it tells you how far you are from the spawn.

What you need

  • 10 bullets for the Ito quest.
  • 10,000 yen if you’re trying to become a hybrid after getting the heart.
  • If you’re only hunting the heart, the quest route is usually the most reliable because it skips the spawn RNG.

Fast tip

If you want the quickest route, farm bullets from bosses first, then finish Ito’s quest instead of waiting around for a map spawn.

A recent guide also repeats the same idea: you can either find the heart in the world or complete the heart quest for a free one.

TL;DR: Talk to Ito, get 10 bullets, and claim the Devil/Chainsaw Heart ; otherwise, hunt the random spawn every 30 minutes.
