SABURO
Episodes 37-42
Hakaida's human form
is Saburo ("third son"). Although Jiro plays the guitar (and Ichiro in Kikaida-01
plays the trumpet), Saburo plays no instrument, though he never the
less makes music, by whistling.

Saburo carried a long
bladed, harder than any other metal knife, the Destruction Blade, which
transforms into the Hakaida Shot when Saburo transforms into Hakaida.
Saburo's Theme Lyrics
Saburo (and Hakaida) was played by Mayama, Juji (who retired from acting after wards).
