This leads us to the case involving sudden silences and a sister worried about her brother being so obsessed in creating the ultimate masterpiece. This is the part of the episode where we see Takeru trying to act more responsible, only to fail miserably. Him trying to hide the fact that he was beaten badly in the previous episode was only made clear by his actions in this episode.
Speaking of Specter, we learn more about him in this episode. First is that he knows Akari at some point in his life, and second, his sister is a Ganma Eyecon for some reason. Considering that Specter's sister also knows Akari, you can easily figure out that these three are really close at some point in their lives before Specter became well, Specter. The scene where he spared Akari's life and what he did later in the episode added some more depth to the character. It tells us that there is some humanity in this mysterious new Rider, that there is something more beyond his spooky appearance.
I got to be honest, I was surprised with the move, but considering his act earlier in the episode, him just standing there doing nothing is the best way they handled Specter doing a kind deed. That being said, it is time for Ghost Beethoven Damashii's debut. To put it simply, I really love this form's debut, his move set being sound-based attacks is kinda ironic considering that Beethoven has some hearing issues in his lifetime, but who cares, he is a musician that made good music despite his disability.
