Episode 50

That Unforgettable Face is the 50th episode of the InuYasha anime.

Plot
Sango is battling demons with Kirara. She commits herself again to keeping Kohaku safe from Naraku. She hears Kagome scream, and runs towards them. Inuyasha and Miroku face off against Kagura, who is satisfied that all is going according to Naraku's plan.

Kagome falls as she is running away from Kohaku, who is trying to kill her on Naraku's command. As Kohaku stands over her with his weapon raised, hesitating, Sango and Kirara appear. Sango realizes her brother is still under Naraku's influence. Kohaku runs away. Sango follows him, leaving Kirara to watch Kagome.

Kagura and her demons attack Inuyasha and Miroku. Kagura taunts Inuyasha that he won't draw Tetsusaiga. Shippo realizes (aloud) that Inuyasha still can't control his sword. Inuyasha draws Tetsusaiga but is still not strong enough to wield it. Miroku continues to defend the hut where Kagura thinks Kagome and Kohaku are hiding (and Shippo is hiding), but demons get past him. Kagura realizes that Kohaku is not inside the hut. Miroku realizes Naraku is after Kagome not Kohaku. Kagura admits Kagome was the target all along. Despite the Saimyosho, Miroku uses his Wind Tunnel to give Inuyasha the opening he needs to rescue Kagome and Sango. Inuyasha leaves, Kagura retreats, and Miroku (despite the poison) and Shippo follow Inuyasha.

Sango chases after Kohaku and confronts him. They battle.

Inuyasha finds Kagome and Kirara. Kagome insists Inuyasha follow Sango, she says Kohaku didn't kill her when he had the chance, and Sango doesn't know. Inuyasha realizes that Kohaku may still have a will of his own and races after Sango and Kohaku.

Sango gets the upper hand in the battle, and hesitates over the killing blow. She swears she will kill herself once she has slain her brother, and begs his forgiveness as she raises her weapon. Inuyasha interrupts just in time to save Kohaku's life, allowing him to escape Sango's hold. Kohaku flees, and Inuyasha chases him. Kagura arrives and reveals that part of the reason Kohaku doesn't remember is that he doesn't want to remember. InuYasha tries to jog Kohaku's memory to free him from Naraku's control. Kagura flees with Kohaku in tow.
