ข้อมูลอนิเมะThe Betrayal Knows My Name

Sakurai Yuki was abandoned by his mother and left in an orphanage, where he spent his childhood alone. Now, as a high school student, Yuki has recently begun to have several mysterious dreams that leave him with a nostalgic feeling that he has seen it all before. In the evening he receives a letter from an unknown sender that leaves him worried by its contents. When he answers the cries for help of a fellow student, Yuki is almost hit by a truck but is saved by the quick actions taken by a mysterious silver-eyed man.

Yuki meets a man who introduces himself as Takashiro Giou, who claims to be his older brother and asks him to come with him to Tokyo. Yuki is initially confused by the sudden revelation and as a result (of the female Yuki accusing him of running away) causes his power to break the orphanages' windows. Later, he has a confrontation with Uzuki at school, and his powers almost goes berserk again. Frightened and confused at his growing powers, he runs away only to meet up with Zess who comforts him. As they begin walking, they are attacked by Duras or demons and are saved by Touko and Tsukumo, along with Takashiro who talks about the Giou Clan and how everyone of its members have special powers and that they need his power.

Yuki is troubled after his meeting with Murasame Toko and Tsukumo and Giou Takashiro, head of a family with special powers known as the Giou Clan. Does Yuki belong with Takashiro or with the children of the orphanage? Zess kindly watches over the confused Yuki while agents of evil approach. Zess warns Yuki to remain at the orphanage on Walpurgis Night but that night two orphans go missing and Yuki is asked to help look for them.

While searching for the missing orphans, Yuki receives a call from his classmate Uzuki and heads to school, where he finds someone unexpected. Worried for Yuki, Tsukumo uses his power to find him and heads to his rescue.

Having found his place among the Giou Clan, Yuki decides to travel to Tokyo with Luka and the Zweilt Guardians. On the way there, inexplicable feelings well up inside Yuki as Luka sleeps by his side. Meanwhile, the police bring a case thought to be the work of demons to Takashiro in Tokyo, and two new Zweilt Guardians await Yuki at the police station.

In Tokyo, Yuki and Luka wait for Takashiro as he makes a stop at a police station. A girl is attacked by a man whose identity is revealed to be nothing more than a golem, holding the girl hostage. The girl is then possessed by a Duras, who reveals her motive to about kill Yuki in exchange for being granted a wish. The Voice of God (a Zweilt Guardian) Hotsuma steps into the battlefield with his burning flame.

Yuki and the others finally make their arrival to the Twilight Mansion at dusk. Upon arrival they are greeted by Aya Kureha and Tachibana Giou, the steward and director of the mansion. Yuki is disturbed by the nostalgic feeling surrounding the mansion, almost as if he has seen it all before.

After everyone had breakfast at the Twilight Mansion, Tachibana Giou leads Yuki along with the Zweilt Guardians to the Communal bath which happens to be occupied by Toko Murasame and Aya Kureha. Luka drives Yuki to school in the morning. Outside the school, Kanata Wakamiya attempts to persuade Yuki to return with him but is interrupted by Toko's and Tsukumo's arrival. After the talk with Kanata, Yuki starts to doubt his decision to join the Giou clan. However, Luka reassures him that he should follow whatever he believes in, but suddenly three Mid-villains attack and attempt to capture Yuki.

Yuki sees the scar on Shusei's chest and asks Luka what things he is unable to heal. Luka responds "scars that come from friends". The others are worried about Shusei because he seems unwell. The police come to Takashiro with a missing person case: 8 high-school boys are missing. They seem to think it's tied into the Sleeping Beauty Syndrome. Later, Hotsuma walks Yuki home and flashes back to being picked on as a kid. The other kids find out he can set them on fire and despise him even more. Shusei is his only friend. In the present, Hotsuma finds out his parents have really abandoned him as they want their payment in exchange for him. Yuki runs to comfort him and sees his past. Angered, Hotsuma starts a fire. He flashes back to when he tried to kill himself with his fire, only for Shusei to hold him and convince him to stop. Now, Hotsuma is able to extinguish his fire before it really hurts him or Yuki. Meanwhile, Shusei accepts that he wasn't the one to help Hotsuma and disappears. Hotsuma desperately wants to find him.
