–Sonneillon to Yuuto Kiba, True Volume 3, Life.2


Sonneillon was one of the hundred thousand artificial Devils that were created by Hades using the flesh of Lilith and the Book of Lucifer.


Sonneillon is a short young man with a skinny body and has dark gray hair.


Sonneillon is shown to be quiet and speaks with short words. Like Gressil, Sonneillon also enjoys fighting powerful opponents and inflicting violence on others in order to show his strength. Sonneillon is considered the most childish among his siblings, becoming easily angered at things not going as planned or even from simple taunting.


Sonneillon was born in the Realm of the Dead, created by Hades with Lilith’s flesh in order to use him for his army in opposition to D×D. At some point, he joined Team Black Satan of Darkness Dragon King under the leadership of Zeno to participate in the Azazel Cup.

Powers & Abilities

Immense Demonic Power: A special case among the hundred thousand Devils created by Lilith, Sonneillon‘s demonic power is above Satan-class and he has the potential to become a Super Devil.

  • Crushing (圧壊, Aggai): Sonneillon’s signature ability that allows him to "crush" objects and opponents through the use of an invisible force. Generally used from above to flatten opponents, it can also be used in other directions such as to move Sonneillon himself out of the way of attacks. However, he can lose precision easily if he loses his cool, which often happens due to his quick temper.

Immense Strength: Sonneillon’s strength has been proven he was able defeat Ultimate-class devils and several Low-class Gods in their Rating Games in the Azazel Cup. Even with his limiter on, he was able to hold his own against Yuuto Kiba using his Sword of Betrayer and Rias Gremory, being able to deflect Rias' Power of Destruction with Crushing. He was able to hit Yuuto's sword, wrist and feet in different occasions until losing his focus due to the Knight's taunting.

Flight: Being a Devil, Sonneillon can fly using his devil wings.


  • Sonneillon comes from the demon Soneillon who is the demon of hatred, the fourth prince of Thrones and tempted mankind to hate.
