How to unlock Tsunanori Mido

Answer: open the first Emerald Diorama coffin

Tsunanori Mido unlocks when you open the first coffin in Emerald Diorama. On the initial run, travel east from the starting area toward the white question-mark marker.

Steps

1. Start Emerald Diorama.
2. Travel east from the starting area toward the white question mark.
3. Touch the coffin and defeat the large enemy that appears.
4. Touch the opened coffin to unlock Tsunanori Mido.

If you cannot find the coffin

• Travel east from the initial starting area rather than south through the junction.
• Use the white question mark as the destination marker.
• Defeat the large enemy summoned by the coffin before trying to open it again.

The second coffin unlocks Siugnas and follows a different route.
