The Panty & Stocking guide book says that Stocking flew down from Heaven; no teleportation, no portals, she flew to the ground from Heaven. Given that Heaven resides beyond the Universe, that means that Stocking flew across the universe to save Panty (and sensed and reacted to Scanty & Kneesocks attacks). The radius of the observable universe is 46,500,000,000 lightyears. First for Stockings sword throw...
Timeframe is 3 seconds.

T = 46,500,000,000 lightyears/3s
= 1.4663819e26/299792458
= 4.89132352e17 C

Then for Stocking flying down.
Timeframe is 14 seconds.

T = 1.4663819e26/14s
= 1.04741564e25/299792458
