One Piece - Roronoa Zoro's "Enma" Katana
"Enma is one of the 21 O Wazamono grade swords. It was once wielded by Kozuki Oden alongside his other sword, Ame no Habakiri, and is one of the two only weapons known to have ever injured Kaido. After Oden's death, Enma was inherited by his daughter, Kozuki Hiyori. Hiyori would later gift the sword to Roronoa Zoro in exchange for the latter allowing Shusui, a national treasure, to remain in Wano."
