Jeff

Jeff is a player for Aoba Johsai that is theorized to be Furudate.

History
Jeff joined the Orange Court on October 31, 2018. Their first message in #central-court was a suggestion to add more server specific emotes, which has since spawned a variety of different emotes from the anime and manga that are used regularly. They remained silent until being tagged by the Captain of Karasuno, Moche, on June 2, 2019.

Jeff is Furudate
During the early beginnings of the server, while discussing the manga and speculations on what was to happen next, it became a running joke that Furudate must be a member who was lurking due to the fact that many speculations became reality.

Then, when the announcement calling for tributes for the First Orange Court Hunger Games was posted on February 27, 2019, Jeff reacted to the message to the surprise of the Orange Court, due to their lack of interaction in the past. Since Jeff reacted to the message, it is believed that they have been reading all the messages in the server, which then became the basis for the joke that Jeff is Furudate. From there, members would often refer to Jeff as Furudate, even adding a response to Ukai bot where whenever Furudate was mentioned, Ukai bot would react with, "Oh you mean Jeff?"

On April 10, 2019, the Captain of Karasuno, Moche, tagged Jeff in #kiddie-court, to which they never responded. On June 2, 2019, they were tagged a second time by Moche, but actually answered this time. This then led to the members explaining the theory of Jeff being Furudate to Jeff. Since then, Jeff has embraced his role as Furudate and has become a more active member of the Orange Court, often coming by to joke about new manga updates and fan theories.

Jeff being Furudate remains an unconfirmed theory.
