Mecha modification is not the same as mecha manufacturing. It involves transforming the original model, which sometimes can be even harder than designing a new mecha from scratch. The modification difficulty of this [Vajra] exceeds that of manufacturing because of its stringent requirements. It must not alter the structure and affect mass production, yet it must meet demands for control inertia, protection for chest and back, and enhanced starting explosive power. Using existing equipment to perform the best and most cost-effective modification is the real meaning of modification.
In terms of modification, this [Vajra] is simply perfect and impeccable!
Especially concerning control, protection, explosive power, stability, and balance, the data of this mecha has been raised by half a grade compared to previous human-shaped mechas! So many key data improvements in itself are a miracle!
