As a whole this is is just a simple set of bonuses from the DVD set and is not really a need to watch, if you are bored or just a really big fan go ahead. Even then, I wouldn't particularly recommend it. The first thing that needs to be adressed is, two of the episodes are pretty much the same thing. As well you only get a small amount of screen time for 4 characters and it's ussually just a bit of fan service (not hating, just stating). Finally the last important thing to note is the final episodes has nothing to do with Kenichiand the rest of the cast. To be honest I have no idea why it was even made or put in the DVD set.
