Doubt Doubt (ダウトダウト) is the Servamp of Envy. His Eve is Mikuni Alicein, who also refers to him as Jeje (ジェジェ). He is the third oldest of the Servamps.
Jeje is incredibly tall (made even more so by the addition of three paper bags on his head), as of yet we have not officially seen his face in the story, except for his eyes, as it is always hidden by his bags (or on one occasion by Mikuni's hat). However, in special art from the first chapter we see some of his face and he appears to have black hair (however, this may have changed as some of the character appearances from that art have changed since then). He is usually seen wearing long black robes with two ammo belts around his waist.
Jeje is very calm and quiet - he nearly never talks - and if he does he mostly mumbles. He likes to build ships in a bottle and likes being on his own. He hates it when Mikuni promises him his blood and then breaks his promise, and even knowing Mikuni always says "no" if Jeje wants his blood - Jeje falls for it, believing his Eve and hoping to get some.
Not much is known about his background, he is the third oldest of the Servamps.
At the Servamp meeting to decide if they were to kill Sensei, Doubt Doubt voted yes. He was concerned with Sensei possibly making more servamps and wished to settle things calmly.
He seemed to be alone for a long time until All of Love invited him to the Alicein's mansion. There he used to live in the cellar of the mansion and didn't show himself.
Mikuni's mother formed a contract with him and kept him until Mikuni formed a new contract. He gave him the name Jeje and used him to kill his mother. After that incident, Doubt Doubt left the mansion together with Mikuni.
He followed his Eve and together with him, he joined C3 and the two of them teamed up with Tsurugi Kamiya. He and Tsurugi seemed to talk every night.
Later he and his Eve left C3 again and went their own path.
