With the seinen genre being aimed at young adults, specifically young men between the ages of 18 and 40, we often see seinen with an abundance of violent and action themes. Blood and war not being in a story also doesn't mean that it's childish at all, with some non-violent seinen having very serious adult topics.

The Greatest Seinen Anime Of All Time, Ranked

From Berserk to Vinland Saga, seinen anime cover many genres and themes. The demographic's best series are also among the greatest anime ever.

However, violence doesn't equate to how good a manga is, with many manga having amazing storylines that avoid violence. While some seinen stories may feature violence at the beginning, or indications of violence, the overriding theme of this discussion is non-violence. Vinland Saga is a perfect example of a non-violent manga that, upon its first impression, readers expect to be very violent, but is in fact very anti-violence.

An Eye-Opening Story About Finding Peace

His personal growth throughout this seinen series is one of the most interesting character arcs in all manga, with Makoto Yukimura doing an excellent job of expressing Thorfinn's story.
