The Bloody Rose only sounds whenever a Fangire is detected in the area, its music only heard by Kivat and Wataru, who hears it as a voice commanding him to "Fight", as it pinpoints the exact location the Fangire could be found. When played, the Bloody Rose can also disrupt a Fangire's activity. However, the Bloody Rose is sympathic to Wataru's mentality as it cracked when he fell into a deep depression.

With a stronger resolve, Wataru defeats Taiga to become the new Fangire King as his way of protecting him. After the two finally put their differences aside and defeat the revived Bat Fangire, Wataru and Taiga go into a friendly fight to see who becomes the new King.
