Mitsuru did not expect his seatmate to be a ventriloquist. The shy Komachi Fukuwa is unable to speak and uses a puppet to communicate in her place. Although he is initially surprised, Mitsuru befriends Fukuwa through her eccentric puppet partner. Longing to hear Fukuwa's real voice at some point, Mitsuru arranges to have her teach him the art of ventriloquism; but things do not go as planned when Fukuwa's puppet does all the talking for her.
