It has frequently been stated that Hand in killer7 contradicts killer7 itself. While this is true to an extent, Hand in killer7 contradicting itself is even more pronounced; furthermore, Suda's works have never been a stranger to self-contradiction. Many contradictions can be explained as coming from unreliable sources, as "Spreading the Truth" and "Jaco's Report" are in-universe documents. Even the parts of Hand in killer7 that are presumably objective, such as timelines, are not necessarily reliable. Suda says in the included interview:
- "The chronology in this book is pretty straightforward and covers the basic facts. However, whether or not it is the truth should be viewed with suspicion."
It seems from this statement that players are intended to notice contradictions and not take any information given to them at face value. As such, it can be assumed that the plot-related portions of Hand in killer7 are equally as reliable as any other information: that is, not at all, but not necessarily less reliable. (In other words, it is canon.)
There is also a persistent rumor that Hand in killer7 is its own continuity based on early versions of the game's story. This may be due to the Prototype Of "killer7" comic, which does indeed portray an early scenario; however, it is clearly marked as such. While other sections of Hand in killer7 do use some elements that were cut from the game such as Miss Jacob, this content was apparently still written after the game was complete, and thus written with the game as it was published in mind. There are also several prominent elements of early versions of killer7 such as Sundance Shot that do not appear in Hand in killer7 (outside of the Prototype comic); if the book was really just an overview of an early version of the game, it would surely include those elements.
