I unlocked Legendary Pixie #18- Valkyrie

Password is 'Valhalla'

1) Bring a Pixie to Promiass (I was master rank
but I assume it will trigger at rank A)

2) go to the Goddess Statue (you must explore)

Coincidentally, my Angel was named Valkyrie.

Addendum: Completing this task seem to open all
the other Legendary Pixies. The Password for
Ayane works for me now.

Great job, GoldenBoy! I am glad you got Valkyrie.

Actually it' s Karnab, in one of the funniest
events I've seen. Here's how you get him:

1) Raise a Joker to class A (I used Enma)
2) Bring him to the Goddess Statue (you must explore)
3) The event will give you the password MAD_DOC

I sense a trend in the Goddess statue...

what ruin is the goddess statue in ?

Promiass

Golem, or at least the golem I tried, doesn't
work this way.

I think the goddess statue only works for the Pixie and Joker. If I remember the events right, the pixie event talks about the daughter of Light. Then, the Joker event says that In the light, there is darkness. The Pixie is the angelis light and the Joker is the demonic darkness. Unless there are other relationship they wrote into this, I think it ends there.

Addendum to Legend Joker:
Joker (any)+ Gali= Archreaper
This will be just like combining to get Rags
until you complete the event I think.
