Overall its pretty good considering its close to the actual translation. Some words are different so it may make a huge or little to no change. I like how you are able to view the extras such as cosplay and all that. I would rather look at scanlations online or buying the physical book than this to support Himaruya. (Vol. 5 has been out for some time now.)
