Eventually Kohaku is forced back to Heaven against their will by God, because they have the important task of hatching the eggs from the Tree of Life by singing to them. However, Kohaku deeply misses Shuichiro and realizes they had developed feelings for him. Likewise, Shuichiro misses them and continues to hold on to one of their earrings to try to prevent them from staying in Heaven. Unable to bear the separation, Kohaku returns without God's permission, and the couple is happily reunited. Their reunion is short-lived as the three remaining Angel Masters come to Earth to punish both Kohaku, and Hisui for being in love with a demon. Hisui is stripped of their Angel Master status and is banished from Heaven, to their and Kokuyo's delight. Kohaku, in turn, is stripped of their powers and forced to remain in a small form for the next one hundred years. They are devastated that they could not grant Shuichiro's wish, but as Shuichiro's wish was for Kohaku to stay with him forever, it was one he could not have fulfilled himself.
