The Ace Lancer (Japanese 筆頭ランサー) is a Guild Knight that is a part of the Ace Hunters.
He can be best described as a man filled with wisdom. The Ace Lancer acts as a teacher for newer hunters.
The Ace Lancer is a veteran hunter and biologist. He is greatly trusted by the Hunter's Guild, other corporations, and by his team, especially the Ace Commander, from his perfect track record on each mission he has done. The Ace Lancer has a great understanding of monsters, such as Gore Magala and Chameleos, from his years of experience hunting them down. Through those years, he has mastered the Lance and Gunlance as a hunter, along with trained Ace Palicoes used by some lucky hunters.
The Ace Lancer usually wears an unknown golden armor with his Babel Spear.
