Hi I just finished submitting this album and filled out as much info as I could. I'm having trouble getting the two other artists (one is an arranger and the other is a vocalist). The two in question are 柳英一郎 & 天戸屋 成 or you can just take a look at the tracklisting here instead to get a better idea. They're on the last two songs. I suck at translating names to Romaji neither do I know any reliable source of how to. Would appreciate if anyone could help out. Thanks!
