Manga 4368 Toradora Userrecs

Both manga involving romance around "tsundere" girls and they treat their partner so badly at first till they develop romance feeling while the story progressing. The story and plot are completely different but the similarity between character and the way they share their bond together are obviously the similarity. 

Both are manga adaptations of light novels revolving around the romance of the main protagonist (both goodhearted guys, but not too similar) and the female protagonist, which is a short, temperamental, dangerous, pettan and purposeful girl (but with fragile hearts). Their appearance is also very much alike, with the exception of hair colour, so you can easily fall a little for one or the other, they are already classic tsunderes and a prime example when talking about that type of characters. As a side note the romance and comedy is handled similarly. 

Both of the main characters have frightening appearances that makes other people think they're thugs even though they're actually nice. Both of these are school life comedies, although Toradora is more romance oriented than Angel Densetsu. [2]  

Both are comedy romance manga with characters in highschool, and in both manga a member of the main pair gets into trouble for looking/being scary, and the other one helps them integrate themselves more. 

If you like tsunderes, like me, I've got something just up your alley, my guy, both of these series have the female protagonist being mean to the protagonists in the beginning, hilarity and cute moments ensues, both have mostly the same genre/sub-genre and the artstyle and character design are of great quality, some of the other characters have also their counterparts (kinda), special mention to the best friend of the protagonists, they are total bros in both of them and they both have a saga about them that it's handled similarly, besides that the romance in both mangas is handed similarly (in it's certain aspects of course, since Nisekoi is also a harem). Both are recommended (specially if tsunderes are your thing).  

Golden time is similar as the story is done by the same person who wrote Toradora, and you can tell by some of the similar aspects but Golden time uses college students and is bit deeper and less comical as toradora 

The female protagonists are very similar and both main protagonist's love interest are their counterpart's friend or acquaintance. Basically the premise is very similar except where in Omae the male protagonist is an otaku, in Toradora the main protagonist is just a delinquent-looking individual.  

There are some parallels. Such as high school setting, accomplices and conflicting love interests. Note: I haven't read the toradora manga yet. but have watched toradora.
