Name: Sirus
Rank: Crusader of Valor
Age: 2,549 years old (He's 24 in looks)
Weapon: Sliver Lancet

Personity:
Sirus may look intimating at first glance, but he's a nice but quiet fellow once you get used to him. Sirus often looks out for the other crusaders including during battle, so he's quite loyal to the LAMO including Serena.
Sirus isn't talkative like Serena is, but he'll talk if you want his advice on battle and stuff being a well experienced fighter though keeps a few certion experiences to himself.

Information:
Sirus is one of the more experienced fighters of LAMO though he does have a more quiet side to him than mets the eye. Sirus is currently in a relationship with Serena, a Sustainer...heck they were already in a relationship before they joined LAMO.
The two know there duties very well though; so they often spend there free time together before one of them has to leave for a mission. They kinda tight lip about it but he says they didn't...well "Do it" yet.

Sirus is a troubled about Serena about what happened during an incident before they joined LAMO; which nearly costed him his life from saving his lover; he'll explion if you ask him nicely.
To put it simply when Serena and Sirus were both Guardian angels before they joined LAMO, there job was hunt down demons who escaped from hell before they cause havoc on earth. There current target a large black dragon named Takashi; yeah they found him alright though that's when things went downhill from there.
Takashi overpowered them and was about to kill Serena who was wounded and was about to tear her apart, Sirus manged to get Serena out of the way; yet not enough to save himself from it's jaws; but mangued to get the dragon to let him go by thrusting his lancet into Takashi's left eye.
Afther that Takashi escaped leaving Sirus heavily wounded and his wings torned off and a heart broken Serena.
Sirus survived but still has scars and never was able to re-grow his wings back but can still fly but using his magic to create engery-like wings.
Sirus has no regrets in risking his life or loosing his real wings for Serena; though he's trying to get Serena to forgive herself for what happened, he has no blame..though he does want to fight Takashi once again though.

Sirus's skills is using his Lancet and past battle experinces maded him good at battle tactics; his magic than contorling engery like wings; is using his magic to power up his lancet so it can almost cut anything or create a quick sheild around himself or others, though he must keep his concentration in order to work.
