H-comics is an abbreviation for Hentai comics. Etymologically, Hentai is pervert in Japanese. Based on AMG (Anime, Manga and Game) terms, hentai is AMG that are suitable for 18 years and above because of more sexual content in them.

For your information, H-comics majorly sketched by the Doujinshis. It means these stuffs are not sketch by the original artist from the popular AMG series such as Tite Kubo for Bleach and Masashi Kishimoto for Naruto. But some of manga-ka such as Shin Takahashi for Saikano (Saishuu Heiki Kanojo): She, the Ultimate Weapon make the comics with adding Hentai as the subject or additive to make the story more better.

H-Comics are majorly target to the lovers, Yuri and Yaoi genres. But I feel very disappointed because H-comics include the kids (in 9 to 12 years old range). It is also known as Lolicon or Lolita Complex. Lolicon is childlike female characters are depicted in an erotic manner. These comics with Lolicon contributes to actual sexual abuse of children or pedophile.

Back to the main subject. The notable characters in the famous AMG such as Hyuuga Hinata in Naruto who is shy and innocent girl; going bad. Why? Because most of Doujinshis make the characters as the subject or victim of losing virginity. Based on fakku.net, the notable AMG; not include the original hentai works, Code Geass is the most popular Doujinshi H-comics, 135 entries followed by Bleach, 131 entries and Neon Genesis Evangelion, 126 entries.

As a conclusion, H-comics are interesting comics if they (readers) have high amount of libido (sexual desire and lust) but it is boring if they read it always or many times.
