Sebastian Michealis

Sebastian Michealis, is a former special agent of M.O.N., where he worked under the supervision of Agent Smith. Known for his use of kitchen utensils as his primary weapons, Sebastian became one of M.O.N.'s best agents and assisted in the recruitment of Akame, whom he developed a strong friendship with. Assigned by Director Ciel Phantomhive to watch over the Dragon Ball, he was brainwashed by Vegeta and used as a pawn for his evil schemes. However, following the Attack on the Helicarrier, he was freed from Vegeta's mental control by Akame and joined the Jump Force to fight against Vegeta's Hollow army in the Battle of Amestria, ending the Hollow Invasion before Sebastian returned to his work as an agent of M.O.N..

Sebastian had continued to work for M.O.N. until its collapse following the CCG Uprising, he and the Jump Force worked to bring down the final remnants of the CCG, eventually capturing Investigator Arima and ending the terrorist organization's threat to the world. However, Sebastian was pulled back into the fight as Edward Elric had inadvertently used the CCG as well as some Hollow technology to create the psychotic Homonculous known as Father. As Father tried to destroy the world, he allied himself with Issei Hyoudou and Rias Gremory and Sebastian focused much of his efforts in convincing them to change sides while keeping the Jump Force safe by bringing them into the Phantomhive Vacation home in which he and other servants worked. During the Battle of Hellawes, Sebastian's life was saved by Issei's sacrifice, resulting in Sebastian swearing a debt to his lover, Rias, and retiring from the Jump Force to return to his normal life.

Despite living happily within retirement for a brief time, Sebastian was recruited by Shepard Sorey to aid him during his fight against the newly produced Hellawes Accords, which had forced Sorey to protect his friend Mikleo from being arrested for a crime he did not commit. Feeling he owed a debt to Sorey and Rias which he intended to repay, Sebastian then joined in the Clash of the Jump Force, fighting against Edward Elric who was in support of the Accords. Despite putting up a good fight, Sebastian and most of their team were eventually defeated and then briefly imprisoned at the Raft under the orders of Kakashi Hatake, only to be freed by Sorey and Sebastian returned back to retirement and after striking a deal with Kakashi was placed under house arrest as the strain of being a vigilante affected him and his job.
