Sierinererk of the Wind Breeze Shop complained that there were not enough items to commercialize in the Abyss. Sierinererk said that some special items can be obtained from Asteria Trico, Immortal Pluma, and Granker but that a Shugo couldn't catch them easily. You brought Trico Horn, Immortal Pluma's Feather, and Big Horn Granker Horn as Sierinererk requested.
