Ritsuka lives with his parents, but still feels very lonely. He had an elder brother Seimei who was the closest person to him and the only one who understood him, but Seimei was killed, though most people believe he died in an accident. His burnt body was found at Ritsuka's school deck.

Before that tragedy, at the age of 10, Ritsuka had lived through some kind of shock, which changed completely his personality, and lost his memory about these 10 years (that is the main reason of the conflict between Ritsuka and his Mother who wants back HER son).

Some time after Seimei's death the Aoyagi family moves to a new place and Ritsuka goes to a new school. When the first school day is over, Ritsuka meets Soubi and finds out he was Seimei's friend and together they took part in spell battles as the beloved couple. Soubi promised Seimei to take care about his younger brother and make him his Sacrifice. From this moment Soubi and Ritsuka form a new couple, but their pairing doesn't have a name, because Soubi's code name is Beloved and Ritsuka's is Loveless.

Ritsuka is against any kind of violence, though once he said it is better to hurt a person physically than to hurt their feelings. He is honest, but can't trust others. Later he will overcome this somehow.

The dearest thing in the room for Ritsuka is the computer: Apple Macintosh G4. He spends many hours at it. Ritsuka is a stay-at-home type, but still likes to walk sometimes. Last two years he is mad about computer games, like: PS2, X-box, and some on-line games.

He would like to go to some South island or North Sea... Ritsuka always carries his digital camera to "make memories", because he believes if he doesn't have photos he will forget who he is or even that he exists.

Ritsuka was born on December 21 in 1993.





Agatsuma Soubi is what's known as a "Fighter". Ritsuka is what's known as a "Sacrifice". The two work together to fight in what are known as "Spell Battles". Originally Soubi was Seimei's fighter, however once Seimei died he was ordered to seek out and serve Ritsuka, his twelve year old brother.

By finding Ritsuka he begins to forge a bond with the boy who still has his ears, telling him in the first episode that he won't make him lose his ears yet. Not until he's older. Being a friend of Seimei's, Ritsuka demands several times to know the truth of his death and about the Seven Moons. Soubi continually refuses. He also continually tells Ritsuka he loves him. Ritsuka is never sure if he's lying or not, but as the series goes on he seems to be telling the truth; that he's developed a feeling of love toward Ritsuka. He gave Ritsuka a cell phone, telling him that if he should ever call he would always answer it. But then, Soubi has a tendency to make promises he can't always keep.

 In regards to Hitome, Ritsuka's teacher, he's made it clear that he has no interest in her by declaring he has no interest in women older than him as she is 23.

During the episode "Wareless" he gets super heated when he THINKS Ritsuka is kissing Yuiko on the Ferris Wheel. Later he finds out he was wrong and gains a better attitude toward everyone else.

He seems to have a boyfriend in the beginning of the anime, Kio. Though as time progresses he doesn't seem to be too interested in Kio as his interest and love for Ritsuka grows. Kio, on the other hand... I don't think he's gotten that point just yet. He occasionally calls Soubi a pervert because of his 'infatuation' with Ritsuka.

All in all though, Soubi is still connected to Seimei and not fully connected to Ritsuka as of yet. If Seimei were to be alive, (Ritsuka asked him this) and he commanded him to kill Ritsuka he probably would. When Ritsuka began to cry and run away he grabbed his hand and pulling him to him he told him that if that day ever came he would rather die. A life with Ritsuka means the most to him.
