Fist of the Blue Sky (蒼天の鳥脚) is an item once owned by Peroroncino.
Fist of the Blue Sky was Peroroncino's personal equipment. After he retired from playing YGGDRASIL, Peroroncino passed it to Momonga. Peroroncino said he didn't mind Momonga selling it, but his friend kept it instead and treasured it in the Nazarick's Treasury, inside the most important room where the Avataras are stationed.
