The Japanese mobile game LINE: Monster Farm (LINE:モンスターファーム) has announced a month long collaboration with the Shaman King franchise. The collaboration started on April 30, 2025 and runs through May 31, 2025. Within the collab there is both new 3D models and 2D art created by the LINE: Monster Farm staff. A special Japanese collab page has been created documenting some of the content for the event.

New Monsters and Assist Cards:

  • Yoh
  • Anna
  • Hao

Each of the monsters have an alternate design that is also available. There are also 2 different art designs for each characters as well. There is no new voice lines or Shaman King music included with this collaboration. The following are 3 promotional animations shown on the official website of the 3D character designs used in the collab (no audio):

Hao

Through standard play of the game, the Yoh Asakura monster is given to the players with his standard school uniform. All other characters and assist cards need to be acquired via the gacha. The gacha pull uses in-game currency but can also be purchased with real money. There are no guaranteed pulls for the characters.

Promotional Key Art for the collab

In addition to the new playable monsters there are several other in-game events that are occurring. Some of these events have been expanded upon once Hao was added into the game during the middle of the month. These events provide additional in-game rewards as well as free gacha tickets for the collab event.

  • Monster Grand Prix
  • Collaboration Login Bonus
  • Shaman Fight in Monster Farm
  • Duel Cup (against Yoh, Anna, and then Hao)
  • Ranking Event
  • Breeders Bingo
  • Various LINE and Social Media promotions

The “Shaman Fight in Monster Farm” provides a custom story mode for the collaboration. There was an additional short story as part of the Shaman King themed Ranking Event as well. Both of these stories are only available during the collaboration. As part of the standard monster raising mode, if you use Shaman King themed assist cards, you can unlock some unique side stories which will be accessible after the event. If you do not have the Shaman King themed assist cards, you can borrow them from your LINE friends online to use and view the stories depending on how well you complete the training.

The game is only available in Japanese and can be downloaded for free on the App Store or the Google Play store. The game can be played without a Japanese LINE account, but some multiplayer features and benefits may be limited. Currently there is no English version for the game.
