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, which Yami throws Asta at it. Asta manages to destroy the whirlpool and they make it to the underwater temple (which somehow has air). 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, which one of the people using a 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, which 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, which the priest summons the temple knights. The high priest then teleports the temple and the Black Bulls (except Yami) to another location and explains the rules to them. Yami gets angry that he wasn't included but the high priest tells Yami that he is too strong, which causes Yami to join the priest watch the battles.

When Asta, Magna, Luck, and Gauche encounter temple knights, the high priest tells Yami that his temple knights are strong but is shocked when the temple knights are easily defeated. The high priest says that the game is not over yet and that the three greater knight won't be defeated so easily. In the game Finral is hiding from one of the temple knights and tries to escape. Finral relieves that he can't leave the area, which the high priest sends a monster fish after Finral. Elsewhere Charmy is happily eating food when a temple knight suddenly appears. Charmy is ready to fight by the temple knight easily puts Charmy to sleep. Elsewhere Asta encounters another temple knight, who introduces himself as Kiat and reveals that his dream is to be a dancer who everyone in the kingdom wishes to see. Kiat also reveals that people of the underwater temple can't go in kingdom and that the high priest will allow them to go into the kingdom if the temple knight win the game. Kiat then starts to attack Asta, which Asta reveals his dream and manages to push Kiat back. Kait gets excited about the fight, which Asta and Kiat charge at each other.

Elsewhere, Noelle encounters the temple knight that but Charmy to sleep. Noelle tries to bluff her way out of the fight since she only has defensive spell but the temple knight reveals that she is Kahono and says that she waiting for Noelle to get to the temple.
