C3 (novel series)
Japanese light novel series
C³, also known as C Cube (Japanese: シーキューブ, Hepburn: Shīkyūbu) or Cube×Cursed×Curious, is a Japanese light novel series written by Hazuki Minase, and illustrated by Sasorigatame. C³ is about a high school student named Haruaki Yachi, who receives a mysterious black cube from his father who is overseas. That night, Haruaki is woken by a noise and is surprised to find a girl named Fear Kubrick in his kitchen eating rice crackers. Haruaki confirms that she is the cube, but knows nothing about her past other than that she has a curse on her which she wants broken. Breaking the curse though proves hard as there are organizations that seek to capture or destroy Fear, along with her dark past as a "Cursed Tool" which comes to light. Haruaki vows to protect her though, and is joined along by other allies/friends as the series progresses.
The series was later adapted into a manga, and appeared as a serial in the manga magazine Dengeki Daioh from February 26, 2011, to January 26, 2013. ASCII Media Works then published the chapters in three bound volumes. An anime adaptation came next, which aired on various networks from October 1, 2011, to December 17, 2011. Twelve episodes aired in all, excluding an OVA to the series which was later released on April 25, 2012.

Why this record matters
“C3 (novel series)” is worth following because a concise public description often conceals a longer documentary argument. Here, novel, series and Japanese provides the most credible route into that argument.
Reception evidence should be dated and situated: later canonical status may differ sharply from the work’s initial circulation. The source revision retrieved here is dated Sep 10, 2026. The linked authority identifier is Q484435. The first chronological checks are 2011, 2013 and 2012.
Later fame can flatten the distinction between original context, subsequent adaptation and institutional collecting history. The lead is largely declarative, so disagreement and counter-evidence require a deliberate search beyond the opening account. Authority statements aid reconciliation but still require their own references, qualifiers and ranks to be checked.
