If you liked the Toradora! anime, the Anime-Planet community thinks you'd like:
Shinichiro Nakagami is an everyday high school student, with the exception of having his beautiful and athletic childhood friend Hiromi Yuasa living in his household after the death of her parents. Unfortunately, their relationship is cold at best - Shinichiro can tell that she is suffering, but she acts coldly and distant from her foster family and so he is unable to help ease her sadness. His family is also forcing him to practice a traditional Japanese dance that does not interest him, adding to his frustration. On top of that, he is cursed to misfortune by another girl in school, the eccentric Noe Isurugi. Shinichiro juggles all of these problems on a day-to-day basis as he learns about love and the sadness of those around him.
Well we could start with the usual love polygon, except that both of these have a male protagonist that lives close by the female protagonist. Though True Tears may not be a heavy Rom/Com such as ToraDora, there are similarity in the dialogue and character interactions.
True Tears and Toradora! are both adorable with very individual characters, along with a wonderful deeper meaning.
The 'girl in the sky' is a legend passed down through the ranks of one special family. Armed with the magical puppet skills he learned from his mother, Yukito Kunisaki follows in her footsteps, traveling from place to place, ever searching for that girl in the sky, ever chasing after that legend. His journeys have led him to a small costal town where he meets a girl that has a peculiar interest in him - could she be the one? As events slowly start to unfold in front of his very eyes, Yukito finds himself amidst a story that spans a thousand summers...
How to male main character cares about his friends and doesn't want to lose them/takes care of them should is the main connection here.
Toradora! also contains some of that tear jerking magic and in depth character development that Air has however its not as powerfull as Air in that area because of the comedy side Toradora! has compared to Air.
What is Seiichirou Kitano, a boy with the heart of an angel and the face of a devil, supposed to do when he starts his new life as a first year high school student? Accidently defeat the school "guardian" and become the most famous and feared gang leader in the town, of course! With his "henchmen" Kuroda and Takehisa in tow, Kitano turns a simple act of good will into an all-out war with Hakuun High!
the main character has a look completely opposite of his real nature, and though he tries to do good he is often misunderstood, sure the themes of the animes are different but i enjoyed both of them greatly.
Ten-year-old genius Chiyo, animal-loving Sakaki, loudmouth Tomo, athletic Kagura, weight-conscious Yomi and dim-witted Osaka are six friends who share laughs, good times, and a high school homeroom. With scary (and sometimes perverted) teachers, school festivals, penguin suits and general hilarity abounding, you can be sure that there's never a dull day in the life of one of these students!
While Toradora! has a romantic focus and Azumanga is focused just on slice-of-life comedy, both series have a similar style of comedy, based around the character's wild personalities. This is particularly evident in Toradora! with Minori, who often acts like a more energetic version of Osaka. They also use some of the similar "typical" highschool episodes, like the characters going to a beach house during summer break and a few episodes centered around the school pool. If you thought one series was funny, it's likely you'll enjoy the comedy in the other.
It's the 1930s, and Mafia groups fight for supremacy in American cities. Young Firo joins the secretive Camorra group; a meek street boy, Jacuzzi, finds himself the leader of a gang of thugs; an alchemist is producing a liquor of immortality, and a homunculus tries to retrieve it; and upbeat thieves Isaac and Miria head to New York after failing to strike gold in California. They ride the novel train, the Flying Pussyfoot, across the continent. However they find themselves embroiled in a ruckus caused by gangs, terrorists, serial killers, and others as multiple stories intertwine and unfold on this fateful ride. All are haunted and hunted by the legendary Rail Tracer...
