The second item up for auction, the Space Crystal, or more precisely, a Subspace Crystal of extremely high quality. Its size is large enough to integrate with a super soldier. To grasp the significance of housing a super soldier, it's a high-level privilege only enjoyed by drivers of the sovereign nation's Red and White Cloaks. In other words, when you possess that Space Crystal, it's tantamount to having a Mecha at your side, ready to enter combat at any moment.
As soon as the auction item was announced, it instantly caused a continuous uproar. Space Crystals capable of housing a super soldier are rare. Although the people living in this lawless land are very concerned about war equipment, what really appeals to them are mobile soldiers.
