After the epileptic-pacing of episode four, Yoshiura calms the story down. In this low-key episode, two plots run astride each other: the mystery of Chie's family situation and Rikuo's struggle with artistic creativity by machines. The latter is specifically highlighted as robots and androids further involve themselves into society by way of music, art and family substitutes. Of course, there are some brief hints dropped by Masaki that a larger conspiracy may be abound, but such matters take a back seat to Rikuo attempting to come to terms with the fact that a robot played a piano well enough to meet critical approval and move the audience.
And, after all is said and done, it is what is not spoken that remains some of the more effective scenes, such as Rikuo attempting to maintain face by not sharing an umbrella with the family's android, Sammy.
It's hard to imagine that the series might end next month. Here's hoping that it's just an end to season one, with two soon to follow.
