Satisfy your Mature Side With These 25 Seinen Anime

“Seinen” is used to describe a male demographic between the ages of 18 to 40. Anime targeted towards the seinen crowd can include a number of other genres. The stories can be morally grey, romances are more pragmatic, action is more graphic, and the humor is more adult.

The general way to spot a seinen series is to look for an older lead, a realistic art style, and a more serious story.

 

1. Mushishi

Synopsis


“Mushi”: the most basic forms of life in the world. They exist without any goals or purposes aside from simply “being.” They are beyond the shackles of the words “good” and “evil.” Mushi can exist in countless forms and are capable of mimicking things from the natural world such as plants, diseases, and even phenomena like rainbows.

This is, however, just a vague definition of these entities that inhabit the vibrant world of Mushishi, as to even call them a form of life would be an oversimplification. Detailed information on Mushi is scarce because the majority of humans are unaware of their existence.
