The movie above starts from the lyrics part.
If you move the red dot to the left on the play bar, you can hear the piano and the drums performance.
Lyrics Harumi Huuki/ Translation into Amami languages：Annna Sato. (2018) Theme song of Sego Don Vocal and Piano Version. Avex CLASSICS.
Stand up as a matured person and fly into the future
Keep back tears and shout out
Hold the feelings of the dead
In order to let the world be filled with love
※There seems to be no official translation of the lyrics, so that the translation above is Beelationship version.
