Chapter 1 (Quartet Knights)

From the Future to the Past (未来から過去へ) is the first chapter of Tashiro Yumiya's Black Clover Side-Story: Quartet Knights.

Summary
At a burning house, a wounded man named Freese laments that he was betrayed despite his loyalty to the country. As Freese grabs a necklace, he says he'll never forget this, and that this is not the end because he'll have his revenge.

At another location, Yami, Asta, Noelle, and Finral are walking when Finral starts to complain. Yami tells Finral to stop complaining and that they would not have had to walk if Finral had used his Spatial Magic. Finral replies that that is impossible because this is his first time visiting the place. Noelle adds on that she can't fly. Yami complains that they are useless, but Finral points out that Yami is capable of flying himself. Yami gets angry and asks if Finral has something to say. Finral replies that he didn't say anything wrong. Asta jumps in and says he can't fly either since he has no mana. Yami tells Asta that that is something that people wouldn't want to yell out loud. Asta starts to work out, saying that with his abs of steel, he'll be able to carry them to their destination. Yami, Noelle, and Finral walk away, with Yami telling them to ignore him.

It is explained that Asta was born without any mana, in a world where everyone has mana. Despite this, Asta was able to become a Magic Knight with the Black Bulls, and that he is aiming to become the Wizard King. It is further explained that Asta and his friends have defeated many strong enemies, and that this is just another story within their tale.

Finral asks Yami if the mission they are on is really a mission from the Wizard King. Yami responds that it is, and remembers how Julius told him to look into a new dungeon and report anything that they find to him. Finral complains that he's tired because he recently finished a mission, but Yami dismisses him. Asta announces that he is ready, but Yami says that he should rest a little. Noelle comments about how there is a dungeon all the way out here, which causes Asta to ask if Noelle knows where this place is. Noelle informs him that the area was once a domain under the control of the Freese family. Finral explains that a man known as Freese the Seer had control of this area and used his power to see the future to raise the Freese family to significant power. Asta comments that Freese must have been an amazing person, but Finral says that a group of bandits wiped out the family around 30 years ago. Asta gets upset about this. Noelle thinks Asta is being creepy and asks what's the matter. Asta wonders why Freese didn't use his powers to see that his family would be attacked by bandits. Noelle says that the truth about the Freese family is buried in the past, and compares seeing the future to fortune telling.

Yami tells them to stop talking. They have arrived at their destination: the dungeon. Yami tells them to not let their guard down. As they walk through the dungeon, Noelle notices that she does not feel much mana in the dungeon. Yami explains that this place is pretty old for a dungeon; and that as time has passed, that the mana within the dungeon has withered away. Yami also warns them that there is still Trap Magic active within the dungeon. Asta asks if Yami has been here before since he seems familiar with it. Yami replies that he was sort of here a long time ago.

Suddenly the dungeon starts to shake, and multiple Stone Golems appear from the ground, likely in order to eliminate intruders and to protect the dungeon's treasure. Asta pulls out his Demon-Slayer Sword, saying he'll beat the golems with his Anti Magic. Yami says that he is going to explore the dungeon, but Finral tells him to wait and asks Yami to assist them. Yami tells them to not go easy on themselves and that they should surpass their limits. Yami then bids them farewell and wishes them luck as he leaves. Finral says that that is messed up. However, Asta tells Finral that now is not the time to fool around and that they are going to defeat the golems.

While walking away, Yami remembers when he asked Karna where she was going. Karna replied that what was going to happen now was none other than her revenge. Yami notes what an old memory that is.

Back at the fight, Asta manages to destroy one of the golems. As another golem attacks Asta, Noelle uses her Sea Dragon's Roar to destroy that golem. Asta yells that that spell almost hit him, but Noelle says that Asta was the one that was in the way. Suddenly, Sea Dragon's Roar turns towards Noelle, but Finral uses his Fallen Angel Gate to redirect the spell into destroying another golem. Noelle sighs in relief now that that is done, meanwhile Asta gets hit with rubble. Asta complains that the two are treating him too roughly, but the two dismiss him.

Suddenly, all the rubble comes together to form a large Stone Golem. As the golem attacks, Noelle uses her Sea Dragon's Nest to protect them. Finral notices that the golem's size and power has increased tenfold. Asta says that Yami would kill them if they do not surpass 1 or 2 of their limits, and reminds the two that they are the Black Bulls. This shouldn't be a problem for them. Noelle huffs that Asta didn't need to tell them that. Finral tries to leave this to them and hide, but Noelle demands that he should help them out.

As the golem launches more stones at them with increased power and speed, Noelle realizes that her spell won't be enough to block the attack. Asta pulls out his Demon-Dweller Sword and destroys the stones. He charges forward, saying that he'll fight them and that Noelle should back him up with her Water Magic. Noelle starts to panic but Asta continues fighting. Despite their efforts, Noelle sees that fighting the golems is still difficult with just the two of them. Finral yells that Asta should come back so they can think of a different plan. Asta however, is set on not giving up. He will keep moving forward, and not lose to Yuno. Asta manages to destroy the golem, declaring that never giving up is his magic.

Asta shouts with joy that he did it, but realizes that he's about to hit the ground. After hitting the ground, Nero pecks the top of Asta's head. Finral comments how reckless the way Asta defeated the golem was. Noelle says that for an idiot, that it wasn't a bad way to defeat the golem.

Asta then yells in the direction that Yami wandered off to that they have finished, but there's no response. Asta wonders if Yami didn't hear him. The door that Yami went through explodes, sending Asta flying back. They all run through the doorway, and notice that Yami is lying on the floor. When they reach Yami, they notice that he looks younger.

Suddenly, Yami wakes up and jumps back. He draws his sword and asks who the three are. Asta says that they are Magic Knights, but Yami angrily questions them. Asta decides to introduce himself, and asks who Yami is. Yami comments how there are people that still do not know about him, and says that he's Yami Sukehiro, much to the shock of the three. Asta, Noelle, and Finral then wonder how Yami became younger; Yami wonders what they are talking about. The three continue to discuss what has happened to Yami and what they should do to deal with it. Yami asks if they have seen a woman named Karna. Asta replies that they didn't see anyone else. Yami angrily says that Asta better not be lying to him. Asta insists that he's telling the truth, which Yami accepts. Yami then bids them farewell and turns to leave, but Asta asks where he's going. Yami answers that he is going to find Karna. Asta says that Yami should see a doctor to fix his condition. Finral agrees, and that they should inform the others too. Asta grabs a hold of Yami, which causes Yami to ask if Asta wants to fight. Yami attacks Asta but Asta manages to block his sword. Yami says he will go with them if they can defeat him.

During all this, a woman watches them with a flying eye. She comments that they should keep fighting each other without knowing the truth, and remarks that everything is in the palm of their hand and begins to laugh.
