During the time before the official start of the Artificial Labyrinth Knossos campaign, Reiger was not idle.
When he was handing over magic swords and other materials with the Hephaestos Clan, he entrusted his black sword, Hi-ja, to that forging deity, asking her to work on it once more and remodel the Hi-ja.
The reason is simple: the weapons forged by Hephaestos using Thermo-Stone as the primary material were too powerful, unsuitable for regular use, and could only be used as a trump card. The Fool weapon was far inferior in power to the Hi-ja, and its lightweight advantage, which enhanced the "Lightweight" ability, became less noticeable with the advent of the Giant Gloves and Flying Dragon Talisman.
With the Giant Gloves and Flying Dragon Talisman, the heavy black sword Hi-ja in Reiger's hand, though not as light as the Fool, didn't feel much different.
