Drop down to a chest near the tracks with a Mythril Crystal (31/39) then go to the northern alley for an AP Boost (32/39).
Head to the west side and use High Jump Lv2 and Aerial Dodge Lv2 to snag Twilight #8 near the waterfall. From the waterfall look east and you can spot a chest with a Mythril Shard (30/39) near the trolley. Continue up to Sunset Hill where you can easily obtain Twilight #2 and Twilight #13. Go back into the Underground Concourse and out exit 4 then through the Woods. At the Mansion you’ll get a scene.
