Shonen nekketsu
The most famous kind of manga, Nekketsu, literally means "warm blood". It is a type of manga intended initially for adolescents. A young hero, often an orphan, is naive and voluntarily embarks on a great adventure during which he will fight for good and where each test will allow him to get stronger. This hero is usually accompanied by a group of friends, some of whom are first his first antagonists, with whom he goes through all his adventures. Manga, like Dragon Ball, One Piece or Naruto are among the most famous shonen nekketsu.

The shojo
Shojo is a type of manga created for a young female audience. The stories developed in this genre are often love stories, most of which take place in the school environment (middle school, high school). If the themes of adolescent life - friendship, school - are widely treated, there is a large part of shojo manga that use fantasy: the sub-genre of "magical girl". The manga Sailor Moon illustrates this style.
The seinen
The meaning of seinen is "young man". Manga classified under this label is created for young men, though it is also popular with older men.
Golgo 13 is an archetypal type of the seinen style, with a professional assassin hero who officiates all over the world, always armed with his M-16 A2 rifle.

Another example of this is Golden Kamui, which depicts a former Russian-Japanese war soldier searching of treasure. The hero is generally more mature than in the shonen, with a complicated past.
