Orion: A Sci-Fi Visual Novel - Issaku Ending

As we continue making progress through the different ending routes, we reach Issaku's route, which is a bit unusual compared to the others. For one, we meet most of the other characters who have endings in the first chapter, with the exception of Issaku, who somewhat comes out of nowhere to bring you into his merry band of revolutionaries. From there, your options in interacting with him are fairly limited as his choices don't affect much of anything other than determining the good or bad ends. To make things worse, I can't really tell if we've learned anything special to even justify his route's existence as it seems kind of tacked on. When you see how bad the true ending is, it makes the shortcomings of this ending stand out even more.
