Cast and characters
The "Five":

Aggeliki Labri as Aggela Ioakimidou. There aren't any exact details for Aggela's family except for the fact that at some point in her teens she misbehaved and did something that made her relatives to consider enrolling her in some sort of behaviour-correcting institution. Once she overheard that she left home to live on her own by the time she was 14 years old, constantly changing jobs and locations. Her father was in the plane during the accident.
Other main characters:
Zeta Makripoulia as Amalia Antonopoulou (and narrator). The stewardess killed in the plane accident along with the entire crew and passengers including the relatives of Zoumboulia, Spyros, Fotis and Angela and Dahlia's lover. It is implied during the last episode that she also lost some sort of relative since there was a passenger who had the same surname as she had. After that, she became Spyros' (and the rest of the gang) guardian angel and helps them to find the murderers. She appears as the granddaughter of an old woman, the neighbour of Spyros. Before her death, she was a married woman and member of another gang of five. Finally, after the death of Spyros' grandmother Sophia she reveals who she is and leaves them forever.
Irene Koumarianou as Sophia Baxevani, Spyros' grandmother (deceased). Spyros' grandmother. She brought Spyros up after the death of his parents.

She died after the end of the adventures and like Amalia, she became a guardian angel.
