No longer visible to the group, Jasdero and David attack. After Allen fails to force them out of hiding, the twins fire a new bullet: the green bomb, enclosing Allen in an airless jelly-like blob. Lavi helps and reveals, as he is Bookman's successor, he can identify the key. As he searches for the key, Krory also reveals he can find the Twins, and directs Allen in successfully catching them. To get out of their hold, the Twins release a mud-monster called Jasdevi's Hatred on Allen and Krory, devouring them whole. The Twins then take Lenalee and use her as a shield, angering Allen, who breaks free, only to be kept busy by an illusionary Earl with all the strength of the real one. Lero reveals that when the twins are thinking the same thing they make it real. Lavi finds the key, the masks and illusions disappear, and the Twins are visible once again. They become angered from being called 'kids' and annoyances, so they merge and reveal their true form, Jasdevi, "the Strongest Body Ever Imagined".
Allen et Krory se retrouvent en difficulté lorsque les jumeaux Jasdebi et Debitto fusionnent pour ne former qu'une seule entité du nom de Jasdebi découplant ainsi leurs pouvoirs.
Ya no es visible para el grupo, Jasdero y David atacan. Después de que Allen no logra forzarlos a esconderse, los gemelos disparan una nueva bala: la bomba verde, encerrando a Allen en una burbuja gelatinosa sin aire. Lavi ayuda y revela, ya que es el sucesor de Bookman, puede identificar la clave. Mientras busca la llave, Krory también revela que puede encontrar a los Gemelos, y le indica a Allen que los atrape con éxito.
