Black Clover Wiki

Slotos 「スロトス Surotosu[1] is a mid-ranking devil[2] who serves Nacht Faust, the vice-captain of the Clover Kingdom's Black Bull squad of the Magic Knights.[3]


Slotos as familiar

Slotos as a devil familiar

As a devil familiar, Slotos appears as a small, dark-colored figure with horns, wings, and a tail.

When merged with Shadow Magic, Slotos appears as a large, black figure with black horns and a purple, horse-shaped mask.[4]


Nacht interrupts captains meeting

Nacht summons his devils to hold the captains.

After Nacht Faust interrupts a captains meeting, he summons four masked beasts to stop the captains from attacking him, with Slotos holding back Jack the Ripper. After Julius Novachrono vouches for Nacht, the captains relax and the beasts disappear.[3]

When Asta defeats Liebe and insists on forming a contract of equals with the devil, Slotos appears alongside Gimodelo and the other devils.[5] The devils cling to Nacht's head and shoulders as Nacht enters the circle and compliments Asta's choice. Slotos and the other devils disappear when Gimodelo merges with Nacht to continue Asta and Liebe's training.[6]

After Nacht admits defeat, he leaves behind Gimodelo to continue Asta and Liebe's training since their union needs more work. The devil is terrified of the possibly lethal attack again, and Nacht's other devils comfort Gimodelo.[7]

Nacht in Equus Mode

Nacht and Slotos unite.

While fighting Dante Zogratis, Nacht summons Slotos and merges with the devil in order to withstand the increased gravity and to buy time for Jack the Ripper's Slash Magic to adapt.[8] When the roots of the Tree of Qliphoth suddenly grow, Nacht switches to Plumede.[9]

After the first gate to the underworld opens, two highest-ranking devils—Lilith and Nahamah—appear in Dante's chamber, so Nacht pulls them into another part of the castle and traps them in his Dark Prison Hunting Ground. Nacht dodges around the devils' attacks and positions himself behind Nahamah. He switches to Slotos and kicks Nahamah's back, but his leg passes through the devil's torso as it turns into fire. Nahamah then destroys Nacht's left shield, so Nacht returns to focusing on dodging.[10]

After the Black Bull base smashes through the castle to the ritual chamber, Nacht and his devils watch from above as the other Black Bulls defeat Moris Libardirt and Yami Sukehiro wakes up.[11] Shortly after, the second gate to the underworld opens, and Lucifero partially manifests through the combined bodies of the devils from the first and second levels. Nacht then merges with Slotos in order to withstand Lucifero's gravity.[12][13] After Asta and Liebe slice the monster in half, Nacht separates from Slotos.[14] However, when Lucifero manifests himself from the monster's remains, the King of Devils increases gravity, forcing the humans to prostrate themselves and threatening to crush them, so Nacht and Slotos reunite and begin moving people through shadows to safety.[15]

Nacht restrains Lucifero

Nacht with Slotos and Gimodelo restrain Lucifero.

After being severely beaten, Asta refuses to give up fighting against Lucifero. Nacht tries to dissuade Asta from rejoining the fight, which Asta refuses as well.[16] To help Asta, Nacht assimilates both Gimodelo and Slotos and creates two large dog heads, which chomp down on the devil's arms, and several chains that wrap around the devil's body. Asta is lifted up into the air behind the devil and swings the Demon-Slasher Katana at Lucifero's head, but the devil disperses the restraints and attacks Asta. Nacht then leaps into the air and brings his shields in front of him, but Lucifero's power shatters the shields and forces Nacht out of Unite.[17] Heavily injured, Slotos is unable to help in the rest of the fight.[18]

Battle Prowess[]


  • Toughness 「剛健 Gōken」: When Slotos assimilates with Nacht via Unite Mode: Equus, Nacht's physical resilience is greatly enhanced, allowing him to withstand and move in immense gravity.[19]
