Sirzechs Lucifer

Sirzechs Lucifer, formerly known as Sirzechs Gremory, is one of the most powerful Devils in the Underworld and the former Satan Lucifer, who oversaw Domestic Affairs prior to the events of the Evil Dragon War. He is the eldest child of Zeoticus Gremory and Venelana Gremory, the older brother of Rias Gremory, the husband of Grayfia Lucifuge, and the father of Millicas Gremory. Known as the Crimson Satan, he once led the Four Great Satans and commanded one of the strongest peerages in the Underworld. Sirzechs is widely recognized for his kind, compassionate, and approachable nature. He prefers resolving conflicts through discussion rather than force and consistently prioritizes the well-being of others. Despite his immense power and status, he remains humble and considerate in his interactions. He also has a laid-back and relaxed personality, often approaching situations at his own pace. This occasionally puts him at odds with his more disciplined household, creating lighthearted moments within his family. However, when necessary, Sirzechs can become serious and focused, revealing the full extent of his authority and strength in critical situations. Sirzechs possesses a strong sense of responsibility and self-sacrifice. In his youth, he took part in the Devil Civil War after witnessing unjust loss of innocent lives, driven by a desire to prevent further tragedy. Later, during the crisis involving Trihexa, he chose to remain in a prolonged battle to protect the world, fully aware that it would separate him from his family for an extended period. This decision highlights his dedication to safeguarding others, even at great personal cost. Within his family, Sirzechs is deeply devoted and protective. He shows strong care for his younger sister Rias and takes his role as a father seriously, supporting and encouraging his son. At the same time, he has a playful and lighthearted side, enjoying simple activities with his family and showed an more relaxed attitude.
