Does hentai haram?

Hentai cartoons are not real that's why they are not mahram for anyone or they are not gonna marry anyone so they are not gonna someone else's wife. Allah say's:One Muslim's honor/respect is deposit(amanot)for other muslim. In this verse Allah means not to see others muslim's private parts or look at them with lust Rasul (SA) tell us to not see anyone thigh live or dead. Hentai are not alive creature and how can we say they are dead when they haven’t life anytime? Rasul (SA) also say that eyes zina is see/watch but zina can only be done with alive creature. Watching another person private parts are haram but hentai are not person or someone else's (another girl's)drawing.they are imagine. (Sorry for my bad English)
