The 番外編 ending was 10/10, perfect crossover event. I was surprised to hear the SN1 protagonist speak AND people saying her name. I wish this was the standard. There were lots of great interactions between the SN1 and SN2 cast, but this one with シオン and アカネ was probably my favorite. Not to mention ルヴァイド and イオン are spared, ゼルフィルド doesn't an hero, no one turns into a tree... It's the all-around best ending.

I noticed that レイド and レイム had the same voice actor, but apparently he was only filling in because レイド's original VA couldn't reprise his role in SN2 for whatever reason. I wonder what happened.
