The Tokyo Ghoul manga was originally published in Weekly Young Jump – a seinen magazine – so the series is technically a seinen. However, that hasn’t stopped it from attracting a sizable shonen audience as well – part of its fanbase even considers the show more like a battle shonen than a conventional seinen. Kaneki – the series’ protagonist – is already college-aged by the time the series starts. Tokyo Ghoul also features far more gore, blood, torture, abuse, and horror than any regular shonen.
