POSSIBLE SPOILER::
OK... after about an hour of searching (and accidental thread starting... sorry about that) I finally found this place! I need some help in the Hana Valley and Shinshu Field... I can't get the sun in the correct place in the Inner Hana Valley (if you know what i'm talking about, plz leave suggestions!)
and in the fields i'm having difficulty getting the zone 'decursed' i think i ran out of monsters to kill after a few nightfalls or something like that...
any help is apreciated!

Ok, figured it out on my own... Go to the room adjacent and help susano 'defeat' the bear then roll the ball to the 'altar'. draw the sun in the valley. Watch the tree grow, complete the constellation. 'bloom' both of the saplings. easily odne in less than 15 mins. (at least when i figured out what i was suposed to do =P )
