Rainbow Line after racing

He got the G1 he had been chasing in the 2018 Tenno Sho (Spring), and pulled up lame right after the line: glory and the end of a career in the same minute. He lit up the staying races with the fight you expect from a Stay Gold. After stud duty he now greets visitors at a theme park in Tomakomai.
