This episode is more on the emotional side. Diving into how Kazuki has been carrying the weight of the past for so many years. After a string of funny and hilarious episodes, this one drops an emotional bomb out of nowhere, and honestly that contrast makes it hit even harder, what a rollercoaster! This is the first time I've seen a worried face of Rei, and it does a great job of reflecting on his character. Overall this is 9/10 for me!
