The stage is a certain port city within the Kantou region. There resides Tandouji Alma, who lives a lonely and solitary life. One day, he is approached by Aiba Ruri who asks for his help, for the power of the Sacred Seven which resides within Alma. However, Alma turns her away. In the past, Alma had hurt people with that power. Since that moment, he had foresworn it. But when the peaceful city is attacked by a monster, Alma reluctantly decides to use the Sacred Seven. However, his powers go berserk and the situation becomes even more dire. At that moment, Ruri comes to his aid.
One of main characters of Sacred Seven. He was born with the power of Sacred Seven from his mother's exposure. A few years ago before the series, he lost control of his powers and harmed a lot of people. Hence, the reason he lives in solitary. Alma can only control his true powers if Ruri inserts a special Lightstone in him. He has access to all seven powers (hence the meaning Sacred Seven). Alma used to have a crystal that belong to his mother that was suppose to suppress his powers, but it got thrown into the river by a bully which caused the incident. He has been looking for it ever since, hence developed a habit of looking for rocks.
Another main character of Sacred Seven. She is the daughter of a billionare noble family who were killed by a Darkstone. She created Aiba Foundation to combat against the Darkstones. She is a Lightstone that has the ability to turn a crystal into a Lightstone and insert it into Alma to control his true powers. She became chairman of Alma's school (where she heavily renovated the school) to keep in contact with Alma. She has a twin sister named Aoi who also survived the Darkstone aftermath, but was crystallized. Her whole foundation is occupied with all female maids.
Ruri's personal butler and field commander for the Aiba Foundation. At 18, he graduated from Harvard and is enrolled in Alma's school for his convenience. He became class president when he enrolled. He has his own personal mech to fight Darkstones.
