Return Scroll to Kerning City

I gave Nella 1000 mesos as commission for telling me about various requests from the citizens of map. The first request is from Don Hwang, the owner of the armor shop, who needs materials to craft new armor. I need to defeat 20 Orange Mushroom and 20 Ribbon Pig and collect 10 Orange Mushroom Caps and 10 Pig's Ribbons. It shouldn't be too hard, since Orange Mushroom and Ribbon Pig are commonly found near map.

I met this girl named Shumi in map. She was devastated about losing the lucky coin that she borrowed from a friend, and she asked me to find it for her. She also told me that a bunch of guys draped in white cloth took it from her in the subway, and that I might find them at the Construction Site B1, deep in the station... I should go there first...
