Male. A member of Colorful Peach. Has a prince-like personality. Very soft-hearted. Because he is a dead ringer for Rao, the prince of the Kingdom of Sandrea, he ended up acting as the prince in place of the missing Rao. He is 'looping' through the past to save everyone. He has done this over 1000 times.

Male. The true prince of the Kingdom of Sandrea. Actually Sufi's older brother. Neither of them realizes it. His criteria for action are 'for the Kingdom' and 'for the people of Sandrea.' He can be strict, but he is kind. He disappeared to investigate the cause of the 'Sand Sickness.'

Female. Younger than Japapa and the others. A citizen of the Kingdom of Sandrea. Actually Rao's younger sister. Neither of them realizes it. She also doesn't know the King is her father. Bright and very cute. However, because her own unrecognized power causes those around her to suffer, she has withdrawn into herself. She has been granted the power of the Guardian of the Hourglass, so when Sufi feels danger, the 'Sand Sickness' occurs.

Male. Older than Japapa and the others. Knight Commander of the Kingdom of Sandrea. Hot-blooded. Extremely loyal to the King and Prince. Has more than double the muscle mass of an ordinary person. Thinks muscles are everything. His real name is incredibly long (in Sandrea, names are added as an honor when one does something beneficial for the Kingdom).

Male. Much older than Japapa and the others. The King of the Kingdom of Sandrea. Father to Rao and Sufi. Extremely emaciated. However, he possesses kingly dignity. Since his wife (the Queen of Sandrea) turned into a sand statue due to the 'Sand Sickness,' he hasn't been able to eat much, leading to his emaciation.

Male. A citizen of the Kingdom of Sandrea. Leader of the Revolutionary Army. Because the Kingdom is slow to take measures against the 'Sand Sickness,' he started his own army to stop it. He always operates while riding a large, weapon-like machine. From the outside, his actions look hostile, so he is often mistaken for an enemy, but his goal is exactly the same as Rao's, making him an ally (he was once thought to be the source of the 'Sand Sickness'). He acts to stop the sickness because his lover was turned into a sand statue by it.
