To be honest, I have no idea what "Free! - Iwatobi Swim Club - " is, but this was an entertaining read. It was well-written and only contained a couple of typos.
My only complaints are that the GAME OVERs from examining items seemed kind of cheap, and that "I'm" was never capitalized.
Other than that, this was a delightful read with entertaining characters and a "metric sh*t-tonne" of sci-fi references.
