Z's Longest Day (Part 2) (Zの二番長い日 前編, Z no ni-ban nagai hi zenpen) is the 9th episode of Kekkai Sensen anime.
Blood Battle God" Raju Jugei Shizuyoshi, founder of the Big Dipper Style Blood Technique and Zapp's master brings in a new pupil of his to help with the Elder Blood threat in Hellsalem's Lot.
Raju says that his new disciple is the legitimate heir of Shinatobe branch of the Big Dipper Style Blood Technique, while Zapp is the heir of Kagutsuchi branch and if he was stronger, he would not have need to split the two styles. But Zapp explains that using two styles like that is beyond the capability of humans. The top half of the Blood Breed is on the front of a plane piloted by Raju's disciple. As the plane reaches Hellsalem's Lot, a monster destroys it and Dog Hummer & Deldro Brody grab the front and smash it into a building. Klaus, Zapp and Leonardo quickly go to face it, while Leonardo attempts to get his full name. When Leonardo manages to get the name, he gives it to Klaus and Dog and Deldro take Leonardo and jump off the building. As they fall, Leonardo notices a strange light, which later explodes.
Zapp tries to help the other disciple, but he opens the plane himself, causing Zapp to laugh as he didn't expect half-human, half-fish. Zed finds Zapp disrespectful, but as they prepare to fight the Blood Breed, he realizes he is the other disciple of Raju. The Blood Breed manages to reunite with his other half, but seeing their master not moving, Zapp and Zed realize what they must do and attack him, giving a change for Klaus to seal him. Raju congratulates them, even though comments their level of fighting Blood Breed is garbage, and decides to leave Zed to them and then leaves, without even giving Zed a chance to speak. From overworking and from the shock of the news, Zed faints.
Meanwhile King of Despair, Femt and Aligura were discussing on what King of Despair plans and in the end Aligura gives him a device, which excited the King of Despair. White's condition had worsened and she recalls how the King of Despair entered Black's body. As she wakes up in her room, the King of Despair is there and gives her the device and asking her to take Leonardo's eyes and he will give her brother back. White recalls a time with her father, where she says that they decided with William to call each other Black and White.
