How to unlock Imakoo

Answer: defeat the southern-route final boss as Diva No. 5

Imakoo unlocks when you defeat the final boss beyond the southern portal as Diva No. 5 while carrying an evolved Song of Mana. The character, weapon evolution, and route are all required.

Steps

1. Unlock and select Diva No. 5.
2. Start Emerald Diorama.
3. Obtain and evolve Song of Mana.
4. Continue through the southern portal.
5. Defeat the final boss beyond the portal.

If Imakoo does not unlock

• Confirm that the selected character is Diva No. 5.
• Confirm that Song of Mana has evolved.
• Confirm that you used the southern portal.
• Defeat the final boss beyond the portal rather than an earlier enemy.
