Summary of volumes
Volume 1:

There's not much continuity to the storyline, basically it's introducing all of the major characters. The World Three members each take a crack at causing mayhem around the city in various ways, and each time are defeated by Lan and MegaMan. Lan also meets Chaud for the first time, while MegaMan and ProtoMan become aquainted with each other. It should also be noted that NumberMan is evil in this manga, and a member of the World Three. ShadowMan is also included, but he seems to be an ally of MegaMan.

Volume 2:

Whereas the first Battle Story manga centered around the World Three characters, volume #2 introduces the Gospel mafia. The first chapters begin with Mayl becoming trapped in her house which is filling with gas, caused by Arashi and AirMan. MegaMan and ProtoMan go to save her and Roll, only to meet up with AirMan, QuickMan and CutMan. Dr. Froid is also investigating some disturbances, and jack in IceMan into the network. MegaMan and IceMan face off against CutMan, while ProtoMan goes head to head with QuickMan.

Volume 3:

Part 3 of this manga begins with Bass and ShadowMan. Bass has sealed himself away because he knows he is too powerful. However, the seal becomes broken, and Bass is set free! It's hard to tell whether or not Bass is actually a bad guy in this, since he seems to keep having an inner conflict within his own mind. The fact that he sealed himself away in the first place shows the fact that he does not really wish to harm anyone. MegaMan and ShadowMan each battle Bass, who eventually seals himself up again, only this time underground.

As of last year, all four volumes of the series have been translated into french.

Currently, Viz Media has no official plans to translate/distribute the series in North America. However, they still hold the license to all Shogakukan related Rockman comics, so there's always a chance.
