Karin / karaoke version
GetBackers image song for Kazuki! ^_^ One of my favorite Hoshi songs. Karaoke version also uploaded.
Shikisai no Shizuku
Eien no Mizukairou
All Harukanaru Toki no Naka de songs that Hoshi sings as Eisen, save for the last one which is a Harukanaru Toki no Naka de 2 song.
Lost My Past
Not sure what this is from, if anything, but it's a pretty song and Hoshi sings softer than usual during it.
Shining Tears / karaoke version
From his Shining Tears single (done for the game of the same name). Seems like this is one of his more popular songs.
I Can Fly
Proud of My Lonliness
All Saiyuki songs for Son Goku. ^^
