If you only looked at Karo's physical appearance, his dirty clothes were covered in dust, his blond hair was filthy, and his clothes were quite tattered. He appeared just like any common drunkard found at every bar.
However, as he stood there while yawning and picking at his ear, appearing nothing like a powerful warrior, he still gave everyone a sense that he would be insurmountable. Three minutes had passed already with not a single person daring to step forward.
Everyone present felt an instinctive danger coming from Karo. Although he appeared quite easy to deal with, as long as someone stepped forward, that person would definitely be attacked and sliced in two.
"This is the worst possible opponent. Karo… no, Sword Saint Roland!"
