$100 is Too Cheap is a historical mystery one-shot shounen manga by Yamamoto Kazune that follows Petey, a sharp and curious bounty hunter navigating a world so overrun with bounty hunters that wanted posters vanish almost instantly — all except one. That single poster carries a negative bounty, meaning capturing this criminal would cost the hunter rather than reward them, and nobody dares go near it.

What sets this manga apart is its clever, self-contained premise: in just one chapter, Yamamoto Kazune builds a vivid historical setting packed with dry wit, genuine mystery, and an irresistible hook. Petey's decision to seek out a mystery solver for answers gives the story an engaging investigative edge rarely seen in short-form shounen manga. It rewards curious readers who enjoy tight storytelling, unconventional bounty hunter narratives, and endings that feel genuinely earned rather than rushed.

With just 1 chapter, $100 is Too Cheap is the perfect read for anyone exploring one-shot manga or looking for a complete, high-quality mystery story they can finish in a single sitting — available to read free online in full.
