Black☆Star Part in the Story-The New Student and Soul Observation

There is constant talk concerning Shinigami's son, Death the Kid's enrolment in Shibusen. Black Star, being the person that he is, is angered that there is someone who is talked about more than he is. He then proceeds to go outside and wait for Kid to appear, along with Soul. Kid, however, is three hours late, as he had spent the entire morning making certain that everything is perfectly symmetrical before his departure. Black Star grows even more impatient at his late appearance. When Kid finally does arrive, he immediately begins to admire the supreme symmetry of the school building; however, he is quickly devastated when Black Star ruins the symmetry by standing on and breaking ones of the spikes protruding out the main skull structure of the entrance. This greatly angers Kid and he prepares to do battle with Black Star, who ends up dragging an unwilling Soul into the fight.

During battle, Kid uses his partners, Liz and Patti with great dexterity and handles both Soul and Black Star with extreme ease. When Black Star expresses his frustration at Kid's long-range attacks, Kid decides to switch to close-range hand-to-hand combat, proving that he surpasses even Black Star in martial arts. The fight soon attracts the attention of the students inside the school; leading to Maka, Tsubaki and Stein having to go outside to watch the fight. Asking Maka to see if Death the Kid is Resonating with Liz and Patti, Maka sees that despite it being difficult to wield two Weapons, the three look up to each other, and thus achieve a perfect balance in Soul Wavelengths. On the other hand, Black Star and Soul's efforts to defeat Kid are futile against him

Black Star and Soul decide to attempt to actually work together as a Weapon and Meister pairing. However, their Wavelengths do not match at all, and Black Star cannot lift Soul in Weapon form. Frustrated, he sends his own Wavelength into Soul, which harms the Demon Weapon. In a 'emotional' moment, Soul decides to break up with Black Star as partners, but Black Star declares that they are still best friends. The two friends hug, but their moment is interrupted as Kid - not being able to resist - shoots the two in the head.

With new resolve, the two go against Death the Kid again. They almost manage to hit him, with Black Star managing to feint a kick and then grab Kid's leg to pin him down, which gives Soul an opportunity to slam into him in Weapon form. However, Kid still manages to dodge, and counter-attack the two. He then proceeds to use Death Cannon. Despite the situation looking grim, Black Star boasts that nothing will defeat him. Obviously, Kid's Death Cannon finishes both of them off.

Kid, surprisingly, loses consciousness too for seemingly unknown reasons. It is then revealed by Maka that, when Soul attempted to slash at Kid, he cut some of Kid’s bangs, with Kid not noticing his broken symmetry until after the explosion. Soul and Black Star both agree that this was their 'win from behind.'

Tsubaki then goes to Black Star and asks if he is alright, though, his only concern is if she saw him and how well he did. Black Star is later seen when Shinigami comes to take home.

Black☆Star Part in the Story-Prologue

Black Star defeats Mifune in their first match.

Black Star first appears with Tsubaki on a mission to take down Alcapone and his men. Although Tsubaki reminds him of the Way of Assassination, Black Star ends up giving himself away by making a big entrance right in the middle of the villains' banquet, using Tsubaki in Weapon form like a microphone, much to the Weapon's chagrin. Alcapone's men do not hesitate to attack them, and the two are forced to retreat using Tsubaki's Smoke bomb Mode.

Tsubaki is saddened by their failure, saying that they had not been able to acquire a single soul as of yet, but Black Star remains ecstatic, claiming that he was as 'big as usual' and made a great stage performance. The two contact Shinigami and Tsubaki tells them of their failed mission. Shinigami wonders on why they are failing so much even when they are quite skilled. Black Star interrupts and promises to turn Tsubaki into a Death Scythe, and offers him his autograph as a current substitute, which earns him a chop to the head by Shinigami.

Shinigami then tells them that although he would like to watch over them all the time, things have become problematic recently because Alcapone and his men have begun to go after a Witch Soul of the Witch Angela Leon. He also tells them that Angela has an incredibly strong bodyguard called Mifune and that his soul is more powerful than the average human's. His soul alone will count as ninety-nine souls. Realizing that Mifune's soul and Angela's Witch Soul would immediately turn Tsubaki into a Death Scythe, Black Star eagerly dashes off to face Mifune, with Tsubaki following behind, not waiting to listen to the rest of what Shinigami has to say about Angela.

Tsubaki however, stops Black Star and tells him that in their current state, it would be impossible to defeat Mifune and Angela. They would need to go through this mission properly. Angered by her criticism, Black Star attempts to prove to Tsubaki that he can easily follow the Way of Assassination, by sneaking up on Tsubaki whilst she is bathing at a waterfall. He manages to do it at first, but then ends up screaming when he sees her naked body, which causes an angry Tsubaki to throw a shuriken at him.

As the two make their way to Magic Castle Cinder where Angela and Mifune reside, Tsubaki asks Black Star if he has a plan. He confidently replies that the first thing he will do is make a big entrance, much to Tsubaki's despair. However, Black Star then swears to Tsubaki that he will make her into a Death Scythe, and she smiles and says that she knows he will.

However, as they reach the castle, they see Alcapone's men killed, and they are attacked by Mifune. Mifune asks them if they are after Angela. Black Star introduces himself to Mifune and declares a duel with him as he thinks he is quite strong. Mifune gives the two a chance to leave, but Black Star orders Tsubaki to change into Chain Scythe Mode. Noticing that Black Star is a person from Shibusen, Mifune prepares to attack, engaging in his Infinite One-Sword Style.

Mifune quickly proves to be more than a match for Black Star, as the Meister struggles against his swordsmanship. Mifune says so to Black Star, that his Weapon is the only thing protecting him, and that no matter how potent a Weapon is, if its Meister is not competent, it will be useless. He gives one last chance for Black Star to leave, saying that he does not like to kill a child. However, Black Star, angered at Mifune for calling him a child, proceeds to attack Mifune by throwing Tsubaki at him in Shuriken Mode, followed by Smoke bomb Mode, and then attempts to cut Mifune under cover of the smoke by grabbing one of his katanas. However, his loud voice gives him away, and Mifune strikes him down.

Tsubaki watches on, horrified, thinking Black Star is dead. However, the Meister gets up, and yells at Mifune for hitting him with the back of his blade, saying that only he can do those kind of moves. Mifune instead says he feels sorry for Tsubaki, as she has to put up with him. He calls Black Star a 'small kid.' However, Tsubaki defends Black Star, saying that he can succeed if he tries, despite being a bit of an idiot at times. Black Star, now furious at Mifune, accuses him for trying to stand out more than him, and declares that the main role will always be himself. Deciding to take the fight seriously, he successfully follows the Way of Assassination. By covering himself with Tsubaki's Smoke Bomb Mode, he uses Tsubaki's Dummy Star Mode to distract Mifune, before taking down Mifune with one hit using his Certain Kill: Black☆Star Big Wave. As Mifune is defeated, Black Star states that it obvious he lost to someone as great as him.

He proceeds to interrogate Mifune on the whereabouts of Angela. Mifune refuses to say anything and Black Star is about to lose his patience when Angela herself arrives and begs the two to spare Mifune. Black Star is startled as Angela is only a small child, and that Mifune is defending her until she can fend for herself. Mifune tells Black Star that he can take his soul, but he would fight to the death for Angela. In the end, Black Star does not kill the two, repeating Mifune's words as he leaves, that he would not like to kill a child.

Back at the DWMA, Black Star gives all of Alcapone and his mens' souls to Shinigami, who asks him why he is not taking them when the going is good. Black Star declares that someone as great as him has no need to take credit for someone else's work. He asks for Tsubaki's opinion and she happily agrees.

Later however, Black Star is back to his old tricks again, peeping on Tsubaki in the school baths, which earns him a shuriken thrown into his head.

Soul Eater Maka Albarn Part in the Story-Seiken

Maka is next to Soul when he wakes up from a terrible dream, and tries to comfort him. Later on, Maka asks if she can do anything for Soul; Soul replies with a no. Maka is noticeably saddened by this. Soul tries to cheer her up by saying it is his fault that he is in this condition. This only saddens her more as he makes her leave. Outside of Soul's room, Maka's father asks her to come up to the roof with him.
Up on the roof, Spirit tries to cheer up Maka, which proves fruitless. Maka asks Spirit what he thinks of her mother. When Spirit replies that he loves her, Maka asks why he cheated on her all the time. Spirit tries to run away by asking her if she wants to head back. Maka says they just got there.
Later on, Maka asks Spirit about the Kishin. He then explains the origins of the first one, Asura.
After Black Star and Kid's meeting with Excalibur, Maka, along with Soul who had recovered, shows them a large bouquet of flowers Excalibur had left for them in their classroom, and a message to them that he will be waiting for them.

Soul Eater Maka Albarn Part in the Story-Demon Sword Ragnarok

Maka and Soul go on a mission in Italy. After a run-in with the Materazzi, the two successfully defeat and acquire the soul of Sonson J. After a brief conversation with Soul, Maka detects an unusual soul within a church and decides to investigate, believing it to be another Meister and Weapon. She detects the souls of the Materazzi, but to her shock, all of their souls disappear in an instant, as if they have been devoured. The two ride to the church on Soul's motorbike, and enter the building.
The two do encounter a Meister and Weapon: Crona and his/her Weapon partner that shares a symbiotic relationship with him/her, Ragnarok. It is revealed that they had killed all the people present, and they then proceed to attack Maka and Soul. Maka and Soul put up a good fight but are overpowered due to the abilities of Crona's Black Blood. Maka worries about Soul as she realizes that Crona can hurt him, even in Weapon form. However, Soul tells her to keep using him, as he is prepared to die for his Meister. However, Maka is cornered, and is reluctant to use Soul to block one of Crona's blows. Soul transforms into human form and shields her from the blow, acquiring a large scar across his chest. Maka, deeply upset over Soul's sacrifice, refuses to leave him behind as he tells her to escape before losing consciousness. However, the two are saved by Spirit and Stein. Stein assures that he will do what he can to save Soul before fighting Crona and Ragnarok. Maka watches the two battle and eventually they are successful in defeating Crona and Ragnarok, but the sudden appearance of a Witch, Medusa, allows Crona to escape.
Maka, deeply worried about Soul, waits for Stein to finish operating on him outside the dispensary back at Shibusen. When Stein allows her to see him, she tearfully stands at his bedside, promising Soul to become stronger in order to not let him get hurt again. Black Star and Tsubaki then enter to comfort her. Black Star tries to wake Soul up (rather violently), prompting Maka to give him a Maka Chop. They are soon also met by Medusa (who is disguised as the school nurse) with Spirit who tries to flirt with her (Maka also gives him a Maka Chop). Medusa cheers Maka up by telling her that she will definitely become stronger. Unbeknownst to Maka, Soul's bloodstream is invaded by Black Blood during the fight against Crona and Ragnarok.

Soul Eater Maka Albarn Part in the Story-The New Student and Soul Observation

Maka is seen in class watching the new teacher, Stein, prepare to dissect an endangered bird on the brink of extinction. Tsubaki wonders where Black Star and Soul had got to, and Maka jokingly replies that the two may as well become partners since their attitudes are almost the same, which provokes a shocked Tsubaki to object rather violently towards her. Two students then notice Soul and Black Star about to battle somebody outside. Maka tells Stein that, when two Meisters fight on school grounds, one staff member has to forsee it. With that said, Stein brings Tsubaki and Maka with him. They find that Soul and Black Star are fighting Death the Kid and his partners, who had just enrolled into the DWMA.
Outside, Stein teaches Maka about matching Soul Wavelengths with one's partner(s). Maka witnesses the perfect Resonance between Kid and his Weapons and the imperfect Resonance between Soul and Black Star, using her newly acquired Soul Perception. She watches in dismay as the hapless pair fail to act as a Meister and Weapon and end up being defeated by Death the Kid after trying to execute a sneak attack. However, Black Star and Soul win by default as Kid then loses consciousness after coughing up blood. Maka explains that Soul's sneak attack eariler had cut Kid's bangs, making them asymmetrical, and he had fainted because he had just noticed this. She approaches a battered Soul, and gently scolds him for picking pointless fights, which had been what Soul had told her once before. Soul laughs and admits that he had been 'not cool.' The two agree that Black Star can only be partners with Tsubaki. Maka and Soul agree to work together again as they reconcile.
When Death comes to pick up his son, Kid, Maka takes the opportunity to see his soul. She, however cannot see it and leaves it at that. What she does not know, however, is that the reason she cannot see Death's soul is because it covers the entirety of Shibusen.
