Hokuto no Ken 2 Episode 36
As Hyo screams, a spirit appears within his aura, which looks a lot like him and also seems to be yelling in pain. Kuroyasha and Shachi believe it to be the aura of the God of War. Kuroyasha doesn't understand why he would have that aura, as he has entered the evil side of Hokuto Ryuuken. Hyo remembers the time Jukei took a baby away from him and gave him to Raoh and Toki, and then he remembers the name of the baby: Kenshiro. Back in the present, Hyo suddenly stops screaming and the spirit above him vanishes. But his aggression towards Kenshiro hasn't vanished and he goes into a new stance, one that Kuroyasha recognises. He says it is a Hokuto Soukei style stance, which means his lost memories about Hokuto Soukei may have been restored! Hyo uses a technique called Jouma Koushou (Scouring Light Palm) which almost fatally strikes Kenshiro. Whilst Ken is determined to fight on, Kuroyasha says that this situation isn't good as the two will keep fighting each other until neither of them are left standing, they will both die if they keep this up.
Elsewhere, Kaioh moves closer to Lin and asks her if she's done talking about useless things like love and emotions. She is more busy trying to find a way out of this and she happens to find a knife under one of the bed's pillows. She puts it to her throat and threatens to kill herself, but Kaioh laughs at her. He doesn't have and emotions in his heart, as they would only hold him back. His heart is just evil, so he couldn't care less if she kills herself. He then takes a seat and encourages her to do it. Ken and Hyo continue to fight, but when Hyo blocks a strike, Ken looks into his eyes and see they are normal again, if just for a moment. Hyo sees Ken's eyes and how sad they are, but then charges forwards and goes to finish him off with a technique called Manju Maon Ken (Ten Thousand Hand Demon Sound Fist). Kenshiro also moves forward, ready with his last strike to finish Hyo off.
Before the two can clash, Shachi stops Hyo by stabbing through his back. If Ken and Hyo had both fallen in this fight, then Kaioh would take over and the world would enter a new dark age. Shachi wanted Kenshiro to survive, so he could stop him and he had to interrupt their fight in this way. He is about to kill himself as a way of an apology, but Hyo stops him. He tells Shachi it is alright now and that the only person who would have died in the fight was him -he could not defeat his brother. His memories of Kenshiro have finally returned! Hyo says that when that spirit vanished, his memories slowly started to come back to him. As he fought Kenshiro, he began to piece more and more of his past together but he still saw Kenshiro as a warrior, rather than his brother. Now that Shachi has done what he's done, the fight is over and Hyo has recognized his brother.
He asks Kenshiro if he killed a woman called Sayaka. Ken says he hasn't and that he's never even heard of her. Hyo figured as much and has realised that he has been used by Kaioh. He has remembered that Kaioh was the one who took away his memories, not Jukei. Hyo goes on to say that Kaioh thinks love is foolish, but just look: that love was what motivated Shachi to fight for Kenshiro, taking a heavy beating from Kaioh and losing one of his eyes in the process. Hyo has been waiting a long time for his brother's return and he is happy to see him again, and is glad at how strong he has become. The brothers have finally been reunited.
In the manga...
-The order of scenes differs slightly in the manga, such as showing more of the fight between Ken and Hyo before showing Kaioh with Lin.
-Hyo's last move is not named in the anime, but it is in the manga: Manju Maon Ken.
-Kaioh isn't wearing his armor when he's with Lin in the manga. He also gets quite a bit closer to her, and touches her face. Lin is also wearing a much more revealing dress, whilst in the anime, she has her usual clothes.
-In the manga, there is a flashback showing Kaioh and Hyo training, and Kaioh attempting to kill Hyo, but is stopped by Jukei. This scene was used earlier in the anime, in the previous episode.
-Near the end of the episode, "Wind & Rain" begins to play. This is the second and last time the song is used in the series.
-When Kaioh tells Lin to go ahead and kill herself, his gloves have fingernails painted on them.
