The prequel special itself is also serialized, and a chapter preface will be published in an appropriate place after every 50,000 words of the main text.

Titled "The Truth of History", it is tentatively set as a five-part series, namely "Dusk", "Twilight", "Midnight", "Night", and "Dawn"

This Gaiden is related to the text itself, but it is not inseparable, as a fun historical supplement to the ultimate history of Transformers.
