I agree, this episode was amazing! Seeing what Hope's Peak Academy was like before everything went down is really cool.
Yeah the voice actors are doing a great job! The only thing I will say is that I wish the original voice actor for Fuyuhiko could have made it back, but his replacement is pretty good, so it's not too big of a deal. It will be interesting to see where the story goes. You're right, seeing the characters animated was great!
What is everyone's favorite characters from this one? Mine definitely is Fuyuhiko, followed closely by Hajime.
