Soubi is a mystery. An obscured fragment of Ritsuka's dreams, a shadowed figure that never declares his intent. Around Soubi, Ritsuka is always in the dark. It is a scary place, a place where souls are swallowed whole and he can't find Seimei.
Soubi is a puzzle piece, a black one that fits somewhere in the night sky. It's not vital to the image, but instead to the grand picture.
To Ritsuka's heart, he is the missing piece.
And when Soubi rests a kiss upon the sacrifice's forehead and brushes his chin with his sheets, Ritsuka can't help but welcome incoming dreams of his mystery. Even if he never discovers those answers he seeks in his fighter, Ritsuka is momentarily content with being loved and accepted so.
Besides, with the lights out and Soubi so close, Ritsuka feels safer than he can ever remember being.
Mystery or not.
