Kuoh Academy, After School.
"Katase's jugs are impressive!" a bald perverted male said.
"Yeah, but I prefer Murayama's legs." a perverted black-haired male wearing glasses said.
"Guys, you might want to keep it down." a third male stated.
"Issei, you're such a killjoy." the bald pervert replied.
"To be fair, we have been getting beatings from them for the last month every time we try to peek on the Girls Kendo Club due to how loud we've been. I'm not stupid enough to try peeping on the Student Council, the Swimming Club, or even the Occult Research Club. I also get the bad feeling that we're being watched, Matsuda." Issei whispered.
"I've seen the Two Great Onee-Sama watching you from the roof, Issei. I'd say that the Occult Research Club might try to kidnap you and then Akeno and Rias will ride your bones until you pass out." the black-haired pervert whispered back.
"If you remember Motohama, Yuuto Kiba is part of the Occult Research and I'm not homosexual the last time I checked my sexual orientation. Toujou Koneko is also in there and she's a loli, so I'd rather not screw with jailbait." Issei whispered.
Unknown to Issei, Matsuda, and Motohama, they were being watched but it wasn't either of the Two Great Onee-Sama. It was a black-haired girl who was scantily-clad wielding a red spear that was made out of light in her right hand. "I hate having to do this, but you must die Issei." the girl whispered before throwing her spear at Issei, a hint of sadness being evident in her tone.
"I don't think this will be a good week for me at all, guys. Today's Monday and my horoscope- GAAAHHH!" Issei started but was interrupted by the red lightspear piercing through his chest. He got a good look at it and knew that he would die soon as the lightspear had gone through his heart. He then fell forward a moment later, dead.
"I'm sorry boys, but I need to get Issei's body away from here." the black-haired girl from earlier said as she pulled the lightspear out of Issei before lifting his body and putting it over her shoulder. "I'll alter your memories so that you don't remember me and that you got the Kendo girls on your case because you got too loud mouthing your perverted fantasies." she stated before casting a spell that altered Matsuda and Motohama's memories. It took a few seconds to take effect, but when it did the black-haired girl was gone along with Issei's body and that the two perverts were surrounded by furious members of the Girls Kendo Club.
"Well well, look what we have here. The Perverted Trio, but the odd thing is that Issei isn't here. We'll deal with him later, right now you two are gonna get it!" Katase exclaimed.
The screams of the two perverts could be heard as the Girls Kendo Club gave them a beating. As this occurred, the Two Great Onee-Sama just got onto the roof along with a different girl who had black hair. "Unfortunately by the time my familiar saw the Fallen Angel, there was nothing that I could do to save Issei. I'm sorry, Sona." Rias said to the new black-haired girl.
"It truly is unfortunate. I'll notify his parents and the rest of the student body that he died from a heart attack." Sona replied.
"I sensed some odd energy from that Fallen Angel that was suspiciously similar to Evil Pieces, Rias. I have the feeling that she'll try to reincarnate him. She seemed sad about killing Issei for some reason, and not just because she could sense that he had a Sacred Gear." Akeno stated.
Meanwhile near Issei's house, the Fallen Angel from earlier set up a barrier after confirming that nobody was home and pulled four badges from somewhere before putting them on his body and chanted, "In the name of Raynare, I call to you Issei Hyoudou, to be reborn as my subordinate. You my private, flow with the tide of the Grigori, and live under my command."
The badges then glowed brightly before sinking into his chest. A few moments passed by before the wound created by her lightspear began to heal. The process took a few minutes and when it ended Issei coughed a couple of times before his breathing returned to normal. Raynare sighed in relief that the Fel Badges worked, otherwise this would have been the third failure she experienced using these. She went into the house and into Issei's room before undressing him and then putting him into bed.
-The next day-
Issei's House, Early Morning.
Issei woke up slowly, noticing that he was in his bedroom. He thought to himself, 'What happened to me? Last thing I can remember is being speared through the heart near the Training Hall.'
"Ah, I'm glad to see that you're awake Issei." a feminine voice said calmly. Looking to his right, he saw a girl with long black hair dressed in only a black bra and panties. He began to have perverted thoughts before he suddenly shook them out and asked, "Do you know what happened to me yesterday, Miss?"
"I'm sorry to say this Issei, but I had killed you before bringing you home and bringing you back to life. My name is Raynare. I'm a Fallen Angel." Raynare replied, but noticed a hint of anger in his eyes and added, "Before you try to kill me, please let me explain why I had to do that."
Issei returned to a normal expression and then Raynare stated, "I was assigned here along with three others by Azazel, the current leader of the Fallen Angels. My fellows are Dohnaseek, Kalawarner, and Mittelt. Unfortunately, when we arrived and took up residence in an abandoned church that's in town Dohnaseek betrayed us and brainwashed Kalawarner and Mittelt before attempting to do the same with me. Fortunately for both of us, I was immune. Unfortunately, he then blackmailed me into going along with his plan, threatening to rape and kill both Kalawarner and Mittelt before doing the same with me if I didn't agree to go along with it."
"What is Dohnaseek planning to do?" Issei asked.
"He's planning to steal a Sacred Gear from a girl named Asia Argento. She's a former nun who was recently kicked out of the Church for healing a Devil. The ritual that he intends to use for this will kill her and I don't want her to suffer that fate. I'm trying to do things low-key so that Dohnaseek doesn't suspect anything. Speaking of which, I won't be able to accompany you to Kuoh Academy because not only am I not enrolled there but I need to return to the abandoned church so that Dohnaseek doesn't get suspicious of me. He didn't think that I would immediately get back after killing you on account of destroying all evidence that I killed you, hence why after I killed you I altered the memories of your perverted buddies. Can you pass along a message to either the Student Council President or the Occult Research Club that I wish to speak with them?"
Fallen Angel Fel Badge system
Background text:
The Fallen Angels were the first faction to pull their forces out of the Great War. Until recently, they did not have a way of increasing their numbers aside from making regular Angels fall and normal population increases. Created as an experiment by Azazel with help from Raynare, the newly coined Fel Badges are currently undertaking an experimental trial phase before going into widespread usage. Raynare's badges however possess a bug that makes them unable to reincarnate anyone unless they are either dying or recently deceased and possess a Sacred Gear. After some consultation with Azazel and the rest of the Cadre, it was decided that the badges would teach new Fallen Angels about combat situations without the risk of actually dying if Raynare's Fel Badges passed the trial phase and that new badges would be compatible with any humans, not just Sacred Gear holders.
Each Fel Badge is associated with a military rank and their enhancements are based on what is to be expected from those ranks. As Fallen Angels operate in small cells,
- Sergeant: These badges increase the eyesight and magic power of the user, giving them an edge when it comes to ranged attacks and magic abilities. This does come at the cost of their physical defense and strength, so getting in close will render their advantages useless. Captains can use the [Switch] technique with any Sergeant badge, regardless of if they are being used or not. Sergeants cost five Privates.
- Corporal: These badges increase the physical agility, defense, speed, and strength of those who bear them, although not to the same extent as the Rook and Knight Evil Pieces. Anyone who bears these badges is also rendered incapable of using magic. Corporals cost three Privates.
- Medic*: These badges enhance the effectiveness of healing spells and techniques that the user possesses. They have very weak combat ability, so users should avoid attracting the enemy's attention. Medics cost seven Privates.
- Warrant Officer: Out of all the Fel Badges, the Warrant Officer is the one that is considered the strongest. One who bears a Warrant Officer badge has access to all of the enhanced capabilities of the Corporal, Medic, and Sergeant badges without any of the drawbacks. A Warrant Officer is worth eleven Privates.
- Private: The Private badge is the weakest of the Fel Badges, but it can serve as a surprisingly devastating wild card if used strategically. To represent this, in enemy territory or with their Captain's permission, any Private can use a power known as [Rank Up], which allows them to use the capabilities of the other three badges for as long as anyone in their unit is in battle with an enemy. Privates are, appropriately enough, worth one Private badge.
- Captain: Unlike the other badges, the Captain 'badge' is used by the leader of a Fallen Angel cell. For now, the only Captain badge is in the possession of Raynare, a Pureblood Fallen Angel. Captains are similar to Privates in that they do not possess any particular strengths or weaknesses. Captains are also not ranked by Private badges.
* Medics are classified as non-combatants, hence why they are very weak if they have to fight enemies at all.
