Master Oden in Yo-kai Watch 2

Complete the Oden of the Soul quest series, and Master Oden will join automatically.

As for Master Oden's locations, he doesn't have any strict locations, for he shows up in random location all over Springdale during clear nights when Terror Time is not active. Since he moves with each clear night, the player must prepare beforehand for the sake of convenience: • 3 Steppa Souls for Part 1 • 3 Mochismo Souls for Part 2 • and 3 Robbinyu Souls for Part 3

Tip: Using the hand button on the bottom screen will let you search the whole map area for the blue flag without having to explore it. Most of the time, a human NPC named Gus will spawn instead of him, in which case, you can reload a save from before you slept till night and look again.

He is required for a Baffle Board in Shopper's Row at night, east of the Everymart. This allows Oden to be purchased from Shopper's Row Everymart.
