In the world Black cloverSecre Swallowtail, otherwise known as Nero, is a member of the Magic Knights known as the Black Bulls, a group of mages who serve as protectors of the land.

Although born a noble person, Secre was not treated with much importance and instead became a servant to Prince Lemiel Silvamillion Clover, the first Wizard King at the time. However, Secre possessed a unique magical ability known as Sealing Magic, which gave her the ability to seal or unseal objects and magic. She is initially seen as a bird in the series.

From bird to man, Secre's journey through life

Was Asta's secret but unexpected companion actually human?

Secre is one of the most underrated characters in Black Clover, the reason why she is initially seen as a bird is because five hundred years before the events of the main story, she was a servant of Prince Lemiel and worked with him to create various magical objects. However, when a high-level devil attacked the Clover Kingdom, Lemiel sacrificed himself to save the kingdom and Secre had to use a powerful amount of magic to seal his body into a statue, the magic was so powerful that it turned Secre into an anti-magic bird. In her bird form, Secre (also known as Nero) eventually meets Asta and sits on his head for most of her journey as a silent but guiding companion.

don't worry about me Just take Asta and get out of here!


Throughout the series, Secre still remains in bird form and supports Asta from the shadows. During the Elf Reincarnation Arc, Secre sees an opportunity to fight a demon from her past with her awakened master, Prince Lemiel, and transforms into her human form, revealing her true form to Asta and the Black Bull group. This scene is one of the key scenes in terms of Secre's character development as he is no longer just a bird but a human. The admiration he has for Asta is evident even in his fight with the devil, and he realizes that his anti-magic abilities are the key to saving the world. He also has his own personality in human form and is seen to have a sarcastic or blank quality most of the time.

How strong is the secret and what magic does it use?

Secre is eventually accepted into the Black Bulls and becomes an important member of the team. Her ability to use her sealing magic to seal and unseal anything, such as magical items or even magical power, is a powerful form of magic. Her sealing magic is what she used to seal Lemiel into a statute, this form of magic is forbidden and requires an immense amount of magic, resulting in her turning into a bird as a curse. Secre is also able to use her sealing magic in battle, grabbing items or spells at will. She is also able to use healing magic by healing others and covering their injuries with recovery magic, which is seen during her fight against the powerful devil when she heals Prince Lemiel and Asta between attacks.


Although she doesn't appear to be strong, Secre can use her deep knowledge of magic and history to strategize during battles. She is able to seal people into objects and can also transform into a bird at will. In terms of her ranking, Secre is ranked as a Stage 6 Mage, but due to her ability to use forbidden magic, she is also ranked as an Arcane Stage Mage, which is effective when it comes to fighting demons. With Secre's other abilities, she can use her mana to sense the location of magical items. He also has a three-leaf grimoire that contains a number of sealing spells.
