When Perfikot was crafting Steam Armor for Beifa, she referenced the design blessed by the War God, making it better suited to the female figure, and the overall appearance more slender.
Hence, even when Beifa donned the armor and followed Perfikot, it wouldn't seem particularly bulky.
Normally-sized Steam Knights tend to be somewhat cumbersome, making it inconvenient to stay close to Perfikot for protection indoors.
In contrast, Beifa's armor doesn't face such issues, and can maneuver freely.
Aside from the unique nature of divine materials allowing Perfikot to easily attempt more precise structures that require high material standards, this is also due to Perfikot's research on the War God armor.
That set of armor was designed for females, and after two blessings from the War God, its structure closely fits the female form while leaning more towards a robust-looking armor than a mecha.
Because of this, Perfikot could further optimize her own armor design by referencing it.
