So I was walking down the aisle of a bookstore when I noticed a manga with a cream-coloured cover and a red eyeball looking back at me. There weren't any content samples on display, but the text on the wrap-around all seemed to indicate that the manga, titled Kouisho Radio (後遺症ラジオ) or "After-effect Radio", was a scary story. Curiosity piqued, I grabbed a copy to check out.
