digimon chronicle
Digimon Chronicle is a storyline accompanying the 2004 Digimon v-pet line.
Originally rumored to be a new, full-blown manga to replace Digimon Adventure V-Tamer 01, it eventually transpired to be mostly prose text, printed in the booklets which accompanied the Pendulum X digital pets. These booklets also contained short, non-sequitur six-page "mangas". There are four "chapters", one sold with the Pendulum X 1.0, another with the Pendulum X 1.5, another with the Pendulum X 2.0, and the final chapter with the Pendulum X 3.0.
