Assassination Classroom: Meeting Time is a cute 10 minute episode about how Koro-sensei met Karasuma that you can watch at any point before, during or after the main anime for a bit of extra content. The story is very simple and it just concerns a first meeting between Koro-sensei and Karasuma, who are therefore the two main characters in this special. Their personalities are neat and reflective of the main anime. The animation is quite good and it has the same animation style/quality as the main anime. The voice acting and sound are also good and the voice actors are all the same as inthe main anime as well.

Overall this is a fun small special to watch for a bit of extra content.
