These are shoujo manga that I enjoyed. However, I think there are some flaws that prevent the series from being great. This is just my opinion :)
These manga are either on my want to read list or my stalled/currently reading. Eyeshield 21 (38 volumes), Negima! Magister Negi Magi & Nejima!? Neo (45 volumes).
These series are shows I have not seen or are currently stalled/watching. I add all series together to come to the episode length but spin-offs are not necessarily added to the total. Status: D.Gray-man (103 eps), Gintama, Gintama', & Gintama 2012...
Series I have not read yet or am currently watching/stalled. Fushigi Yuugi: Genbu Kaiden & Fushigi Yûgi (30 Volumes).
