The Killer Inside #4

The cover of this fourth volume from Ki-oon's seinen line is genuinely unsettling in the best way: a close-up face of a dark-haired figure is split by a shattered mirror effect, revealing two distinctly different eyes — one clear and composed, the other shadowed and dark — suggesting a fractured dual nature at the heart of the series. Writer Hajime Inoryu and artist Shota Ito continue their psychological thriller with this 2021 installment, and even the cover design alone communicates how skillfully they play with the idea of hidden selves. If you've been following this series, volume four's artwork promises the same tense, quietly disturbing atmosphere that makes The Killer Inside such a compelling read.
