Utsumi’s Past Works and Why This Matters
Understanding Utsumi’s previous work helps set expectations for Hundred Note. Her storytelling is notable for its mood, compact pacing, and willingness to explore uncomfortable truths—elements that often translate well into mystery and suspense manga.
The Shadows of Who We Once Were (Nare no Hate no Bokura)
Launched in Weekly Shōnen Magazine in January 2020 before moving to Magazine Pocket in November 2020, The Shadows of Who We Once Were ran until July 2021 and collected eight volumes. The series showcased Utsumi’s ability to blend character-driven drama with mystery elements, earning enough attention to warrant a live-action adaptation in June 2023. That adaptation highlighted the adaptability of Utsumi’s narratives to other media, a promising sign for future works.
Until Your Bones Rot (Hone ga Kusaru Made)
Serialized from 2016 to 2018 on Manga Box, Until Your Bones Rot spanned seven volumes and was released digitally in English by Kodansha USA. This earlier title helped establish Utsumi’s voice: gritty, atmospheric, and emotionally intense. Fans of this series will likely recognize thematic through-lines—morally gray characters, claustrophobic tension, and revelations that bite hard.
What to Expect from Hundred Note -Ugly Duckling-
Based on Utsumi’s established approach, Hundred Note is likely to include:
- Psychological mystery with an emphasis on character motivations
- Slow-burn reveals that reframe earlier events
- Atmospheric linework and panels that favor mood over spectacle
- Themes of transformation or identity (hinted by “Ugly Duckling”)
Utsumi often builds narratives that demand close reading; expect carefully placed visual and textual clues that reward attentive readers. If you enjoy thrillers that prioritize tension and moral ambiguity over action set-pieces, this will likely be a strong fit.
Adaptation Potential: Could Hundred Note Reach TV or Film?
Given the recent live-action adaptation of The Shadows of Who We Once Were, Hundred Note has a reasonable chance of attracting adaptation interest if it gains traction. Utsumi’s stories have cinematic qualities—tight plotting, striking dramatic beats, and strong character arcs—which translate well to live-action formats. However, adaptation typically depends on popularity and editorial backing, so early serialization performance will be key.

Why Mystery Fans Should Be Excited

The “Ugly Duckling” motif promises explorations of identity, transformation, or societal perception—fertile ground for layered mysteries where appearances deceive and motivations are murky.
