"Kunoichi Rumble: The Rivals Get Serious!" (ライバル激突!オトメ心は本気モード, Raibaru Gekitotsu! Otome Gokoro wa Honki Mōdo) is episode 41 of the original Naruto anime.
Kankurō easily wins his battle against Misumi by tricking him into attacking Karasu, Kankurō's puppet. In retaliation, Karasu snaps Misumi's neck, though he survives due to his ability to contort himself. The fourth match is between Sakura Haruno and Ino Yamanaka. After the two exchange insults, they decide to take the battle seriously.
