Warning, Gantz is a pure seinen, with physical, psychological and carnal violence. Some scenes are really cruel and hurt me so...

There's also Neon Genesis Evangelion. It's my favorite manga since my childhood. Officially, it's a familial shonen, but it flirts with seinen topics. Again, the psychological violence is rude in this one, especially in the sequel movie "The End of Evangelion". But for this one, I advice you to watch the original anime instead of reading the manga.
