The chapter about Akiyama is a cute little story about an event in Akiyama's past that really doesn't add anything to the main story in the manga but is still fun to read if you're interested in the character. The other five chapters have their own stories of varying, but overall pretty good, quality that are completely unrelated from the liar game but all at least seem to have some kind of psychological aspect.
Aside from Akiyama the characters are all interesting enough and they don't develop a lot since the stories are so short. The art is okay.
Overall this is a neat collection of small stories. If you like(d) liar game the first chapter is worth reading and the other chapters can also be fun to read even though they aren't connected to Liar game in any way.
