post an animé series which had an unconvincing ending!

GetBackers

The animé was a Super Epic Sky Rocketing one..........they showed the limitless Fortress..and a dit that the babylone city on haut, retour au début of the limitless fortress is the dangerous place of all.......they didnt montrer it ou revealed anything about that..and they didnt showed full power of Ban Miedo and Ginji Amano..........in the end everything became a mystery.........and they really had a good strory line and they finished the animé without revealing anything............it was really a unconvincing ending!

i relly want a continuation from the last episode of this anime..........!!!!!!!
