In a flashback, Byakuya decides to leave a glass record for Senku containing a message from him. In the present, Senku and his group create a record player.
Senku unveils the record player to the village and plays it. To their amazement, Byakuya's voice is heard as he introduces himself. He then stops with the formalities as he addresses Senku, knowing full well that he is free by now and is hearing the message. Byakuya wants to voice confidence in him before stopping, since he knows his son wouldn't go for sappy father-son moments. Senku laughs that Byakuya truly gets him, as Kohaku notes that Senku is cold to his father while Kokuyo sadly notes she is no better.
Byakuya then has Lillian perform a song preformed with the crew helping. The villagers are in awe at the sound.
