Without doubt, engineering is a job that burns money. As the investor of the Roland Series Robots, as the honorary director of the Sulfur Mountain City Engineering Association, after investing without limits to develop the series, the Beyar Brothers of the Safe Merchant Group is already on the verge of bankruptcy.
Even so, the Roland series remains as an immature product. Although the towering giant robot may look impressive, if it doesn't even have the combat ability of a Legend-rank, then it is just a slightly higher-tier punching bag in the Underground World which is full of experts. But, if they were to add in a few high-tier parts to increase its combat ability, then the funds required would be astronomical. Thus, they thought of finding an investor who is in need of higher-end military power on the Surface.
