Go to the Village in the Shade of Trees (木かげの集落) in the Azlan Region (アズラン地方) E1. Examining the dust behind the trees will trigger a cutscene and a boss. After you beat the boss, talk to Sen (セン).
Head back to Azlan and talk to Maetake (マエタケ) at F6
Go back to the Azlan Region and examin the shining spot at D4 for the item Round Stone (まるい石ころ)
Check the dust at E1 in the Azlan Region again and hand the stone over to Sen for a cutscene.
