RPG Insanity

Already beaten the Naptolum(?) Fortress (something along with that) and was asked to go north of Royal City (Shama Forests?) but the quest indicator says I need to do something on Seiya. Check every NPC yet still none happening. Pls help.

It's been a while. So, I'm not sure, have you done the part where you need 5 or 6 Shama Hearts that are dropped by enemies in the Shama Forest and examine the stone at the end of the forest?
