If you liked the Dragon Drive manga, the Anime-Planet community thinks you'd like:
Both of these mangas are about a game which revolves around dueling with virtual monsters, yet in both stories the monsters turn out to be more than just virtual creatures. Additionally, both series feature some big company with dark designs, who try to use the creatures to their own ends. Lastly, there is a very close resemblance in the artwork as well. These two series have so many similarities that you would swear they were actually 2 parts of the same series.
They both revolve around kids and virtual dragons/mythical creatures and have similar plot lines. If you liked one, you'd definitely like the other.
Misaki Suzuhara is a young girl who traveled to Tokyo to live with a relative, but ended up becoming involved in the greatest game of all time: Angelic Layer! In this fast-paced competition, players customize dolls and fight them in arenas of all sizes, hoping to gain experience and perhaps win the greatest tournament of them all! With new friends to meet and new enemies to defeat, the best time of Misaki's life seems to be just beginning. Join Misaki as she struggles to be the best, even in the face of overwhelming odds.
It may seem a bit strange to tie dragons and angels together, but in both Angelic Layer and Dragon Drive, the main character is determined to succeed, no matter the cost. These kids start out playing a game and get really absorbed into it. As time passes, they make names for themselves by meeting every challenge head on.
In the year 200X, the cyber network has spread to the four corners of the planet. Internet activities are supported by characters called NetNavis who reside inside an electronic device, and their users are known as NetOps. Lan Hikari is a young boy who chooses to battle his NetNavi known as MegaMan against others. With his exceptional skills, the Cybernet Criminal Investigations Department takes an interest in Lan and grants him a special license to battle the forces of evil that threaten DenTech City. Together, Lan and MegaMan will fight together to put a stop to the dark organization World Three and other nefarious foes that lurk in the Undernet!
In both of these mangas, kids start playing a game that turns into much more. Each kid has a partner that they use to fight other teams- in one manga, it's personal programs that interact with the net for them, and in the other, it's a dragon with unique attacks. If you liked one, you should check out the other too.
