Synopsis
"Still I haven't done it!" A sad voice echoing in the courtroom. It is a trial of an adventurer caught on suspicion of molesting in a packed dungeon. There are various proceedings in the Guiners Kingdom Court, such as tax evasion allegations that disguise weapons as SM tools and power harassment by skilled adventurers. When you leave the dungeon, both the swordfighter and the wise man are just people. It is the law that governs the kingdom-that is, the strongest job in the world of swords and magic is the lawyer. Kiel, who is famous for being undefeated in such a country, is a vicious lawyer who has everything to intimidate and forge. One day, after hearing his rumors, Airi, a kind-hearted wizard girl who wants to save his teacher, appears.
