If you liked the Air Gear anime, the Anime-Planet community thinks you'd like:
18 year-old Takumi has been delivering tofu for his father's shop since he was 13, learning to drive fast in all weather conditions. One night he is seen racing down the mountain by Keisuke, one of the best amateur racers in Japan. Quickly overtaken by Takumi, Keisuke vows to challenge the White Hachi Roku and discover the mystery behind its driver's skills.
Long ago the infamous Gol D. Roger was the strongest and most powerful pirate on the seas. As he was about to be executed he revealed that he hid all of his wealth, including the legendary treasure known as One Piece, on an island at the end of the Grand Line - a treacherous and truly unpredictable sea. Monkey D. Luffy is a spirited, energetic and somewhat dim-witted young man with a very big dream: to find One Piece and become the Pirate King! However Luffy is no ordinary boy, as when he was younger he ate one of the Devil's Fruits and gained its power to become a Rubber Man. Now in this grand age of pirates Luffy sets out to gather a crew and sail to the most dangerous sea in the world so that he can fulfill his dream... and maybe even his appetite!
just like the Team Kogarasumaru, One Piece also has their team Mugiwara Kaizoku-dan. Air Gear has their emblem and One Piece has their Jolly Roger. They also risk their lives protecting it.
Mikoto Shinozaki is a normal high student with unfortunate normal problems: he's terrible at sports, has no special talents and is bullied by everyone at his school. That is, until one day Yuki, his beautiful, long-time crush, asks the boy if he'll join her brother's cycling team. Desperate to gain her affection, Mikoto tries his best to learn how to ride a bike to not look foolish in the process, soon discovering that he actually enjoys the sport! Now, Mikoto will try his hardest to become the best cyclist in the world, encountering hardships, trials and successes along the way.
If you liked Air Gear for Ikki's guts, never give up attitude and amazing skill improvement speed then you might also like this very epic Over Drive. Over Drive is a sports anime but it is a very serious and has miraculous improvement speed like in Hajime no Ippo and Air Gear.'
Eventhough if you did not like sports anime or cycling, I still have to say you this: This is totally epic, humorous and keeps you on your toes. Makes you feel if sports was this exciting why I haven't been watching it more.
Beneath Tokyo lies a city whose inhabitants have inherited a natural ability to control the elements. After a civil uprising, two girls surface from the sub-terra in a bid to escape from this secret world. Together, Chelsea and Ruri stumble upon Asagi Rumina, a man who becomes determined to protect them from those who would pursue the maiden of life. After a close encounter with death, Rumina learns that he must develop a skill of his own to keep his newfound friends safe, especially as it seems to be his responsibility to stop the impending doom rising to take over the planet’s surface. Will his power of wind be enough to take on The Company, or will he be forced to kneel before those brandishing electricity, ice and shadow?
Tokyo Underground and Air Gear have colourful characters, especially the personalities in the girls. Air Gear has "tricks" while Tokyo Underground has supernatural powers. I found that the near-end events resembled one another in both titles, specifically the one-on-one battles. There is plenty of action and adventure to enjoy in these two anime.
In the kingdom of Urak, the tower of Druaga is a source of fear and death; it is the cause of disease and monster attacks, and climbing it is impossible given the ferocity of the monsters within – until now. It is the Summer of Anu, a period that occurs once every five years during which the monsters are weakened. Jil, a guardian, is one adventurer whose goal is to reach the top level and slay the tower’s creator, the demon Druaga, and finally bring peace to Uruk with the help of a powerful artifact found within. However, Jil and his friends aren’t the only ones who aim for the top; it’s a race to the finish!
To prove yourself have always been a tought business. But even after that, there are still people who won't look at you the way you desire. Bot Air Gear and Tower of Druaga: the Aegis of Uruk follow the same theme. Ikki from Air Gear and Jil from Tower of Druaga are able to prove themselves in the long run for, not to say, a little cheap price. The difference between the two, however, is that Ikki succeeds in making his dream come true without losing anything, while Jil is left behind by the person he believed in the most. After all both anime have an open end and maybe will continue soon enough with a second season!
