Arc 5

The unnamed arc is the 5th arc of Yūki Tabata's Black Clover.

This arc revolves around the Black Bull's mission to the Seabed Temple to retrieve one of the Magic Stones.

The Mission
The Black Bulls arrive at Raque for a mission but most of them decides to have fun at the beach. While having fun on the beach the Black Bulls fun turns into a ruckus. When Asta remembers about the mission Yami shows up and buries them in the sand (with their heads in sticking out) as punishment. Yami tells them that he has learned that the temple is at the bottom of the sea and that their only chance to get there is during the night of a full moon. Yami then tells Noelle is the only one that can get them there and will have to surpass her limits to do it.

Later that night, Noelle is training to control her magic and thinking about how she has to get better. Noelle suddenly hears a noise and finds Asta. Asta and Noelle start to talk and decide to train together to help each other out. Asta notice someone is singing, which Asta and Noelle notice that a girl is singing on a rock.

The girl notices Asta and Noelle and gladly heads out and introduces herself as Kahono. Noelle then introduces herself and Asta (As Dumpster) and asks why Kahono is here. Kahono replies that she was practicing her singing and that she wants to be an idol. Kahono notices that Asta is injured and heals him with her song magic to heal him. Kahono then asks to be their friend which Asta and Noelle agree to. Kahono then gives Noelle advice to not suppress her mana to much or that she will loose control of her magic. Kahono also tells her that using a good memory to obtain peace of mind works best but Noelle only thinks about how her family looks down on her.

Noelle decides to continue training and is helped by Asta and Kahono for a few days. On the night of the full moon Noelle hasn't been about to gain control yet. Asta tells her to stop thinking and just release all her mana. Noelle tells Asta that it won't go right, which Asta replies that he would save her if anything happens. Noelle then releases her all her mana and is about to fall unconscious when she hears the Black Bulls cheer her on. Noelle thinks about how the Black Bulls have acknowledged her and manages to gain control of her spell. Noelle then gets excited but loses control of her spell and falls into Asta's arms. Noelle then looks for Kahono, but Kahono leaves looking forward to meeting Noelle at the temple.

Playing a Game
After being unable to find Kahono, Noelle gathers the rest of the Black Bulls in her spell and heads into the ocean. Once they reach the barrier of the grand magic zone, they manage to get through the rough current and witness a beautiful view. A whirlpool magic of mana suddenly appears before them, at which Yami throws Asta, who manages to destroy the whirlpool. They make it to the Seabed Temple. The Black Bulls then head closer to the temple when they happen to see people, who cheerfully greet them. Yami asks the people for their boss with an angry look, and one of the people using an equally angry face tells them that they want the High Priest. The people then guide the Black Bulls to the temple.

When the Black Bulls enter the temple, they are suddenly attacked by a giant fish. Luck, Magna, and Gauche easily defeat the fish, and the High Priest gladly greets them and reveals that the fish was made by his magic. The High Priest reveals that he knows what they are after and that they are going to have play a game to get it. After some convincing the Black Bulls agree to play, and the High Priest summons the temple's other priests and then teleports them and the Black Bulls (except Yami) to another location, after which he explains the rules. Yami gets angry that he was not included but the High Priest tells Yami that he is too strong, which causes Yami to join the priest in watching the battles.

When Asta, Magna, Luck, and Gauche encounter four priests, the High Priest tells Yami that his priests are strong but is shocked when the priests are easily defeated. The High Priest says that the game is not over yet and that the three greater priests will not be defeated so easily. In the game Finral is hiding from the Hammerhead Shark Priest and tries to escape. Finral realizes that he cannot leave the area, and the High Priest sends a monster fish after Finral. Elsewhere Charmy is happily eating food when the Dolphin Priest suddenly appears. Charmy is ready to fight but the priest easily puts Charmy to sleep. Elsewhere Asta encounters the Swordfish Priest, who introduces himself as Kiato and reveals that his dream is to be a dancer whom everyone in the kingdom wishes to see. Kiato also reveals that people of the Seabed Temple cannot go to the Clover Kingdom but the High Priest will allow one to go if a priest wins the game. Kiato then starts to attack Asta, and Asta reveals his dream and manages to push Kiato back. Kaito gets excited about the fight, and Asta and Kiato charge at each other.

Elsewhere, Noelle encounters the priest that but Charmy to sleep. Noelle tries to bluff her way out of the fight since she only has defensive spells but the priest reveals that she is Kahono and says that she was waiting for Noelle to get to the temple. Elsewhere Yami and the High Priest witness that Vanessa was able to defeat the Anglerfish Priest. Yami says that he should have put money on the bet, while the High Priest thinks about how he will be able to win if his son and grandchildren start to get serious. Back in the game, Noelle asks Kahono why she helped her back of the beach, to which Kahono says that while she was practicing her magic, she was also looking for people to bring to the temple to play the game. Noelle replies that Kahono only used her but Kahono says that they really are friends and that she is going to fight Noelle with everything she has.

Kahono then tries to put Noelle to sleep but Noelle counters by putting up a barrier. Kahono switches to a different spell to take down the barrier. Noelle attacks but the spell completely misses. Kahono asks what Noelle is doing, to which Noelle replies that she still cannot control her mana. Kahono tells her that Noelle is able to control her mana but does not want to hurt anyone. Kahono then tries to get her to fight seriously for her goal. Elsewhere Asta is battling Kiato and is having a difficult time reading his opponent's movements. Kiato says that Asta's sword is useless when not fighting against magic and tells Asta that he can give up if he wants. Asta thinks that he might lose but then decides to try and mimic his opponent's movements. Kiato says that that will not help Asta, but Asta says that he will mimic Kiato's magic with his muscles. Asta then manages to dodge Kiato's attack and counters. Kiato's wonders what kind of reflexes Asta has, while Yami excitedly says that Asta's abilities are far greater then that.

Another Player
Elsewhere Luck and Magna are having a difficult time against Gio, who apologizes for what the High Priest is putting them through. Luck notices that the priest has a large amount of mana, and thinks about how this priest is the strongest one here. Gio then activates a spell to finish the fight quickly. Luck and Magna charge at the priest, when Vetto and three members of the White Night Eye suddenly appear and decide to join them. Back at Raque's beach Sekke is terrified after having witnessed Vetto defeat fifty Magic Knights. At the temple Luck and Magna witness Vetto crush Gio, and Luck thinks about how Vetto's mana far surpasses Yami's. Gio suddenly gets up and asks Vetto what he is doing here. Vetto tells him that they are here for the magic stone and that he will give everyone despair before stealing the stone. Vetto then sends three other White Night Eye members to search the area. Gio tells Vetto to leave, but Vetto says that the priest is going to have to make him. Gio uses his magic to attack with a hammer but Vetto use his Beast Magic to protect himself. Vetto then uses his magic to easily take down Gio along with Luck and Magna.

The high priest is shocked that his son was defeated so easily and that he had never seen a person as powerful as Vetto. Yami decides to end the game to go fight, which the high priest asks who Vetto is. Yami tells him that Vetto is a high ranking member of a terrorist group. The high priest then tells Yami that they cannot leave because of his magic. Yami decides to break the wall to leave but notices that a member of the White Night Eye has trapped him and the high priest in a barrier. Vetto notices that Yami is here and tells Yami to watch as he kills all of Yami's comrades. Yami asks if he can talk to his comrades, to which the high priest says that Yami can. Yami then tells everyone that the White Night Eye is here and that they are have to surpass their limits to face them. The high priest then tells them that he is changing the rules to that they have unlimited amount of time and that they just have to defeat the White Night Eye members to pass. Asta and Kiato decide to postpone their fight in order to combat the next enemy. Elsewhere Vetto wonders who will be his next prey when Luck and Magna suddenly get up and say that they will not be defeated so easily. Vetto gets excited and says that he cannot wait until they succumb to despair.
