TB Manga II contains four short stories not included in the anime series. These stories take place between Star of Sorrow and Yesterday, Today, and Tomorrow. Abel, Tres, and Esther travel from Istavan to Rome by train, foot and ship.
Adrenaline Drive tells the story of Count Gyula's protege who seeks to find and kill the Count's killer.
The Sleeping Beauty tells about the trio travel through a dense, dark forest created by a lovesick Methuselah.
Roselyne et les Lion intruduces Leon who the trio to combat a a vampire lord who uses dope to keepp his Terran subjects placid.
Gate of Heaven introduces Prof. William Wadesworth who joins the group on board a luxury liner to battle a ship board singer whow is a siren(Methuselah.)
The Abel,Tres, Esther,Leon,and Professor of the manga are not versions seen in the anime series. On a ranking of the three versions of TB on a darkness scale, I would place the graphic novels as the darkest. The anime is the lightest, and the manga is half way between the other two. I enjoyed all three forms. The changes in sequence, how and when permanent characters are introduced between the books and series show how
well the series writers managed to blend the numerous stories into a comprehensive and seemless series.
