If Raziel ought to execute his own little brother Ryen, he would've perform it himself but instead he let Ryias take charge on it. The blade never pierced his body, it's just a mere stab he got at the back because Raziel ordered it. Also, Raziel's subordinates never got in trouble with Ryen, they avoided him because that's Raziel's orders, his subordinates only fought Ryen's party, if that's the case, Raziel cared about his brother this whole time he never turned against him, he's somehow lost in thought on how he's able to change his mind to induce him to his side, but Raziel's way of thinking of bringing New World Order are bloodshed, this is how he brought torment to the entire world and how he express his hatred for humans, his triumph for revenge led society in a cull, including innocents. Ryen would never allow that. The spirits are divided into different nature which is scattered throughout the world; Ice Spirit, Fire Spirit, Water Spirit, Wind Spirit, Earth Spirit, lastly Magic Spirit. These spirits could help Ryen on awakening his 5ft Level of Consciousness and Awareness which he greatly needs to become stronger when the day began he battled Raziel and The Titans. If so, one of them are willing to gather, Fire Spirit is... a bit pride.
