Isshou Asonde Kurashitai numbering
The numbering of the chapters of Isshou Asonde Kurashitai is messed up. The chapters labeled v02_001, v02_002a, and v02_002b actually take place after what is currently v02_004a, v02_004b, and v02_005. This is partly a result of the screwy chapter numbering of the original manga. There are 7 chapters, the first five called "Game 1" through "Game 2," followed by "Final 1" and "Final 2". The last two are what are named v02_001, v02_002a, and v02_002b.
I recommend renaming them v02_006, v02_007a, and v02_007b, respectively.
