Ken Rō (剣狼 Sword Wolf) is Rom Stol's sword, which is given to him by his father Kirai. This sword can be used to summon the power to transform into Ken Ryu and then Baikanfu or even perhaps summon the bodies of both at once through 'Pile Formation'. It is the counterpart to Guardi's sword Nagase. The two swords can connect to assemble a more powerful weapon. After Guardi's death, Rom inherits Nagase while Ken Rō's next user is Leina.
