Kane

Kane's name meaning "Battle"
He was an experiment created by some Abyssal Mages trying to take over the afterlife by recreating Satan's power. Taking pieces from an angel and demon they captured and sewing it together with magic and cellular science Kane was born. When the court caught drift of their plan it was shut down and Kane was taken in under the court as a prisoner who was experimented on and used as the court assassin.

Raise Story:
Kane was used as a last resort by Lilith to get rid of Ryuya which ended up being unsuccessful and caused his body to be temporarily destroyed. After Per was put in charge of the Court of Souls they released Kane as a prisoner and he is now allowed to live freely. Seeking to purify his sins he reincarnates corrupt souls/demons under the new court laws set by Per and Saul

Divinum Dies Irae Story:
Joining Heaven's side during Belial's 2nd resistance he was tasked with guarding Karou and the Mansion of the Mind along with other angels. He uses a sword crafted by Saul himself

Nexus Spell:
Undecim Calvus ~ Sanctus Pulviam [Eleven Stud ~ Holy Rain]
Kane acting mainly as a wand, a red string is connected to him from to the caster. With power from his partner he can cut through anything in a wide area (Undecim Calvus) and depending on the person's power level and connection with Kane he can perform the second half of the spell (Sanctus Pulviam) which rains up swords of light that can reincarnate demonic/evil souls.

Extra:

• Refuses to eat green food even if it's just coloured green 
• Though he can read and write he understands very little
• He doesn't understand personal space or how to properly show affection and will hug and kiss anyone
• Though it took a great amount of magic to create Kane he is incapable of doing any magic and can only store and direct it for others
• The scar he received on his right eye is capable of being healed but he choses to leave it since it's what helped him remember his past after having his spiritual body destroyed temporarily
• The pink ribbon he wears, his cross necklace, and his name were gifts to him by Marie 
• After his spiritual body was reconstructed and he was granted a new life he was offered to go by a different name, he politely declined
• Kane shouldn't be allowed to stay in Heaven due to Divine Laws but he was given special permission by Saul
• Though Ryuya was the one that destroyed his body he holds no ill will toward him and considers him a friend now
• Kane is able to resist Belial's call when he was released, no one is certain if this is because of him having more celestial influence in him now or if it's just pure will
• He usually wears 2 different masks since people tend to find his face unsettling (whether it be because he has parts stolen from another angel or for being a half breed) he wears a demon looking one for when he's hunting and a bunny looking one when walking around Heaven
• He's been given the nickname "The Angel of Death" but he resents that
• He's actually not fond of flying and would rather walk places
• He's part Diligence Angel and part Lust demon (since most misunderstand the sin of lust people have trouble finding the lust aspects of his personality) 

Kenelm: Kane's technical Mother Virtue, he has to work with her often but doesn't think much of her besides that she's "a little strange and loud".

Per: Kane has to work with them a lot since he tends to act as a messenger for Heaven and doesn't seem to mind their presence. He's extremely grateful to them for setting him free.

Ryuya: Tried to kill each other in the past and Kane still feels extremely guilty about it though Ryuya has stated "It's no big deal". Anytime Kane has to come to the court he always stops by the library to say hi to Ryuya who doesn't seem to mind. He often tries to get Kane to spar with him to which he politely declines.

Saul: Kane finds great comfort in their presence despite not knowing him very well. He's very grateful that Saul has allowed him to stay in Heaven with Marie despite great protest from others

Eroe: Kane still feels guilty for trying to kill him in the past but Eroe seems understanding and treats him kindly. Since they are both technically Angels of Diligence they sometimes have to work together and Kane can't help but find Eroe's sunny disposition strange.

Lonán: Since they are both technically Angels of Diligence they sometimes have to work together. They don't talk much to each other but don't seem to mind each other's company either.
