Oh Ansatsu Kyoushitsu you had to break my heart.
What a beautiful way to end this story. While the first season spent time establishing the characters of (half) of class E (see my review of the first season) we now spend time on koro-sensei.
Man where we not prepared. This season really builds on the strengths of the last while maintaining the same level of quality and a (mostly) light hearted feel. The story while stale at points never seems to disappoint with even predictable story arcs being enjoyable to watch. We even got to see more of class E with almost all the characters being characters in the end and not just props.
This anime will always have a special place in my heart.
