Tier-5: Shameless
That might seem risky because Ji-woo's one-sword style was different from most other sword techniques out there. The biggest reason for the difference lies in the different sizes and shapes of the swords.
Ji-woo's one-sword style focuses on how he would use his weapon that had strong durability. He would reduce the strength of his forearm and arm to reinforce his shoulder.
Unlike the usual sword, the one that Ji-woo had could not get used to covering every corner of his entire body. So, he had to take advantage of the attacks that came against him.
Blayze, who saw Ji-woo's stance, thought there would be a retaliation. Surprisingly, Ji-woo didn't attack the incoming Red Undead Knights. Instead, he just dodged those creatures with great effort.
