A/N: This is an AU. I love Severus Snape so he will be a main protagonist here.

"What should I do now?" Severus Snape paced irritably in the Headmaster's quarters. 'My quarters', he thought bitterly. After he had killed Albus Dumbledore, he had been crowned as the new headmaster, courtesy of the Dark Lord. That single act had made the dark side hailed him more but scorned hatefully by the light side. He had heard the report of the sighting of one Harry Potter but he had been powerless to sway the Dark Lord army from their target because he needed to protect his students and staffes from the wrath of the Carrows.

He muttered angrily under his breath before his gaze settled on a mirror in the corner of the room. "Shinigami-sama" he muttered lowly before he closed his eyes from the onslaught of the memories of his past lives.

Once, he was a student of DWMA academy. He was the most powerful weapon because he had been made a Death Scythe when he was only 10 years old. Before he had taken his role as Shinigami Death Scythe formally, he and his partner had pleaded to take a dangerous mission in Britain together for the last time. Shinigami had approved this so he and Lily Albarn, his meister had journeyed there.

They had researched about the kishin that had made his headquarters at the wizarding world. At first, they were baffled and curious about the existence of the wizarding world. They managed to trick the headmaster of Hogwarts to enroll there.

They had disguised themselves well. His meister, Lily Albarn became Lily Evans and he, Severus Prince became Severus Snape. He had changed his hairstyle from soft, wavy ebony hair to somehow greasy looking. He crooked his nose to make it like it had been broken several times in the past. One thing he learnt from the academy was appearance could tricked people. They had stayed friends throughout their school year. To avoid their house rivalry, they had staged a fight. To everyone else, it seemed that their friendship had been ruined when the reality was not. He had been inducted as a Death Eater (he had chuckled at the irony) not long after that and he had been working against this so-called Dark Lord ever since.

When Lily decided to marry Potter, the arsehole, he had objected vehemently but there's nothing that he could did to sway his fiery tempered meister. He had reminded her about their objectives coming to the wizarding world and about their impending returned to the Death City. She just laughed at him while telling him to lay off the case for awhile. She just had to mock him to follow his younger brother's lead (the audacity of her!) on relaxing. Honestly, Spirit Albarn was a womaniser even in his younger years. He just rolled his eyes and sighed.

When the kishin decided to kill the Potters due to a prophecy, he had came begging to the Headmsster to save all of them. In his distraught state, he had foolishly agreed to do everything the Headmaster asked him to do in exchanged of that. Unfortunately, even with their combined efforts, they failed to protect the Potters, saved for their only son, the intended target. The Headmaster had manipulated him to protect Harry Potter because he didn't believed the Dark Lord had been gone for good. He had entertained the idea of returning to the Death City several times in the past but only his pride prevented him from it. He was ashamed to face Shinigami-sama and reported his failure in protecting his meister and killing the kishin.

He had been jostled out of his thought by the sound of the ticking of his pocket watch. He glanced to it and sighed wearily. "Just after midnight. Great. Another sleepless night." He turned to face the mirror and contemplated his next action. "Maybe it's time for me to reappear back as a Death Scythe."

He walked towards the mirror while at the same time putting all the privacy charm around his quarters. He knew that the Headmaster's quarters was the most impenetrable in Hogwarts but he won't took any chance. At the same time he cancelled the glamour charm on his hair and nose. He brought his shaking hand to the mirror and incanted under his breath.

"42-42-564. Whenever you want to knock on Death's door" he took a step back after he wrote the number on the mirror. He waited anxiously while the mirror rippled to reveal the face of Shinigami-sama.

"Hello hello~ Who's..." Shinigami-sama halted when he saw who's at the end of the line. "Severus-kun?" he said in wonder.

"Hello, Shinigami-sama. Nice to see you," he smirked. He waited several seconds for the outburst that sure to come and he was not to be disappointed.

"Where are you all this time! Are you alright! What about..."

"One by one, Shinigami-sama. I only have one mouth to speak," he interjected smoothly. The eyeholes that made Shinigami eyes narrowed and he nodded.

"Explain."

With one single command, Severus told him everything. About their failure in killing the kishin, why did he stucked there, what's happening in the wizarding world right now and most importantly, his greatest failure on protecting his own meister.

"So, that's everything" Severus ended his own tale. During his report, Shinigami didn't reacted at all. He gave occasional nodded while remained stoic.

"Ahh, I see" he paused a few seconds. "I'm going to assume that everyone of the inner circle of this Death Eater organization are kishin eggs, right?" Severus nodded. "Then, I'm going to send a few of senior weapon and meister there with our best students from the DWMA to assist you there" Shinigami knew Severus was a proud man. That's why he didn't asked him whether he need assistance but just gave his order. Severus nodded in response.

"Severus-kun, had you eaten any human soul?" Shinigami asked with a stern voice. Severus looked at Shinigami without blinking before he chuckled.

"No, Shinigami-sama. I still remember the academy teaching. I'm a demon weapon so I can only eat kishin eggs" Shinigami exhaled in relieve.

"Now, now~ Do you need me to send someone to wield you~" Shinigami asked in his jovial tone.

"No need, Shinigami-sama. You know that I never let anyone else to wield me except Lily and you. After all this time, I have been an expert on fighting without a meister."

"Alright then. I will send them this morning. If you want to know, the DWMA also have face a situation" Shinigami stated to him while tilting his head to the side.

"What kind of situation?" Severus arched his eyebrow.

"Have you heard about the Kishin Asura?"

"Isn't he the first Kishin ever created? 800 years ago, you skinned him alive and using his skin as a sack, you buried him deep down of the DWMA. You sealed your own soul at the Death City to keep him from ever escaping."

Shinigami looked at him bemused. "I'm not going to ask where did you find that piece of information" he concluded after a while. "Anyway, Kishin Asura had escaped."

"What! How?!" Severus asked in shocked.

"Apparently, Witch Medusa had disguised herself as the academy nurse. She had injected black blood to the kishin. After he had been awakened, he had spread his insanity wavelength to the world. The result of the wavelength was the Witch Arachne revival. Arachne had established Arachnophobia to gain control of Eibon demon tools."

"Too many things happen in my near 30 years of disappearance" Severus mused aloud. Shinigami laughed jovially while shaking his head.

"The most early the back up plan will come is tomorrow night. Can you handle the matter in the mean time?" Shinigami peered at him closely.

"Of course. That's what I've been doing all this time" Severus smirked.

"Alright~ Is that all, Severus-kun?" Severus nodded. "I'll see you soon then. Goodbye~" with that, Shinigami clapped his two big hands together and disappeared.

Severus turned away from the mirror and sat down at his desk. "The final fight is drawing near."

"The final fight is drawing near" Shinigami sighed while spoke to no one in particular.

"What final fight, Shinigami-sama?"

"Ah, Spirit-kun~Stein-kun too? How long are you both here?" Shinigami waved to Spirit and Stein when he saw them coming closer.

"Long enough, Shinigami-sama. This is the result of the final test of this year" Stein handed him a paper that he eagerly accept.

"Oh?~ I want to see Kid's result. I wonder how he did in the final exam" Shinigami perused the content when Stein voice stopped him.

"What did you mean about the final fight?" Shinigami raised his head a little and saw Stein put both his hands in his lab pocket while Spirit crossed his hand while looking at him expectantly. He blinked once before he rolled the paper and vanished it into the thin air.

"Do you know Severus Prince?"

"Severus Prince? Was him the one that had been called weapon prodigy? He and his partner was the only students that had graduated from the academy when they was 10 years old and he had became your Death Scythe."

"His partner was my sister. They had taken a mission at the Britain but since then, there was no news about him" Spirit interjected.

"Severus-kun had called me just now," he ignored the gasps from the other two occupants in the Death Room. "He had asked for assistance to kill the kishin eggs there. Stein, I want you to call Marie, Azusa, Sid, Justin, Maka, Soul, Black Star, Tsubaki, Kid and the Thompson sisters. Ask them to come here" Shinigami ordered.

"Understand" Stein walked out from the Death Room. Spirit started to follow him before Shinigami voice stopped him.

"Spirit-kun?" Spirit turned around to face him. "Call her too. We need her expertise in this matter" Spirit widened his eyes before nodded in acknowledgement.

"Alright. We will meet you here later."

Shinigami turned towards the mirror and sighed. "This will be a long day."
_

"Father, what is this all about?" Kid asked his father when he spotted Azusa, Sid, Stein, Marie, Nygus and Justin in the Death Room. His friends looked with confused expression at the adults.

"Ah, everyone is here~ Good, good~ Come, I want to give you all a mission~" Shinigami sounded too cheerful even for his standard. "This is a suicide mission..."

"Good! I, the almighty Black Star can accomplish the mission by myself! I'm the one who will surpass God one day..."

"Maka Chop!" Black Star, who is in the middle of one of his show-off had been knocked down with blood running profusely from his head. The others looked at Maka in bewilderment.

"That will silence him. Please continue, Shinigami-sama," Maka told him while smiling. Shinigami coughed lightly to diffuse that awkward situation.

"As I was saying, this is a suicide mission. All of you will be going to Britain. There are many kishin eggs to be killed, alongside a kishin" Shinigami explained. The others gasped in surprise.

"Kishin? Is it Asura?" Sid asked.

"No. One of my Death Scythe had tracked him for many years. He had called me early this morning to ask for assistance."

"Forgive me, Shinigami-sama," the others turned to look at Azusa. "I don't know that you had a Death Scythe at Britain?"

"Ah, well this one was the most reclusive person. He had gone tracking this kishin since he graduated. In fact, he and his partner was the only person that had graduated when they were only 10 years old..."

"Hold on. You mean to tell us that he's still alive? After all this time?" Marie widened his eyes in recognition.

"It's true. He had called Shinigami-sama early this morning" Stein told all of them.

"It's unbelievable. It's been too long since he disappeared" Sid remarked.

"Where did he hid himself?" Nygus continued.

"Father" every adults turned to look at the students. "Who's the one that you are talking about? I never heard about him" Kid asked his father while furrowing his brow.

"Well, Severus-kun really knew how to erase his track if he did not want people to find him~" Shinigami laughed.

"But why there was no mentioning about him in the books?" Tsubaki asked.

"Severus Prince is a spy extraordinaire. He can't let people to know where he is when he's still spying" everyone turned to look at the person who was speaking. She had fiery red hair and bright green eyes. She was walking towards them with Spirit accompanying him.

"You're here? Everyone, let me introduce you to Lily Albarn, Severus-kun meister" Shinigami introduced her.

"Albarn?" Maka gasped.

"Hello, Shinigami-sama" Lily nodded to him. "And this must be Maka" Lily knelt in front of Maka. "You look a lot like your mother" Lily smiled to her.

"Maka" Maka swiveled his head to look at his father. "She is your aunt"

"Yes. Your father, sadly speaking is my younger brother" that exclamation had been met with an indignant cries of 'hey!' from Spirit.

"My aunt? But why I never know about you?" Maka asked.

"Long story short, I'm dead and have been been out of commission. If not for Shinigami-sama interference, I will surely stay dead. So right now, I will be your guide to the Hogwarts."

"Hogwarts? Where is that?" Liz frowned.

"Yay, yay we are going to a tour!" Patty made some sort of dance with Black Star while Soul muttered about their idiocy under his breath.

"It's a school for witches and wizards like DWMA. My son went there. I daresay you will get along well with Harry. He have a strong sense of justice" she chuckled and got up from her position. "Well, enough of this pleasantries. Shall we go on our way now? I shall fill you about our mission on the way" she looked pointedly at Shinigami.

"Of course, of course~ Go on~" Shinigami shooed them out with a wave from both his hands. They started to trickle out from the Death Room. "Lily-chan?" Lily turned back. "Bring Severus-kun back to the Death City alive, alright?"

"You don't have to worry, Shinigami-sama. I don't intend to let my best friend die. Not under my watch" Shinigami nodded and watched her out.
