I Was Sold Dirt Cheap, But My Power Level Is Off the Charts Volume 1

In another world, war is waged through battles of humanoid mechanical “Magic Suits.”
These suits are piloted with power called Ludea, intrinsic to each human from birth. One
day, Yuta and his whole high school class are summoned to fight. Why? “People from Earth
have high Ludea Rates.” So they say, but Yuta’s Rate was only 2? As his classmates are
auctioned off for fortunes, Yuta is sold as a slave for next to nothing. But before long, an
encounter with a mysterious white Magic Suit sets him on the path to awaken his hidden
strength! Mecha combat in another world — let the battles begin!
