Although an old anime. Code: Breaker really reminds me of Flame of Recca
Rei Oogami mostly resemble Kurei's personality and demeanor. The blue flame of Rei and the purple flame of Kurei's Flame from Kureinai her beloved who was killed by the one who adopted him. Same as the sacrifice for each power that they have. Rei's sense of taste using his blue flame and Kurei's loveone as his Phoenix Flame.
