Chapter Text
It was odd, definitely odd. Sitting at the desk in a classroom he used to almost explode in his youth. Dazai stared at the array of ingredients, the same ones he used to sneak to see if they would kill him or not- Ah what is he thinking. Dazai continued staring at the ingredients and didn't seem to realize the children flooding through the doors. He forgot how cold it was in the dungeons, the children were warped in scarves, and some had their gloves on still.
“Sir?”, Dazai quickly looked away from the ingredients and met the eyes of a Ginger Gryffindor, probably a Weasley, Dazai mussed to himself.
“Yes?”, Some of the students squeaked, that wasn't supposed to come out so harshly, was he falling back into his Mafia habits... No, he had to make Professor Snape proud. Dazai Cleared his throat and tried again,
“Ah sorry, what was it?”, Some of the student's regained composure at his much kinder tone. Heh, why are children still so easy to manipulate... I guess that's what Mori was thinking when he first saw me, Dazai tried to block the Mafia thoughts out, God how he wished he’d had a normal upbringing, and met Snape through just being accepted here like any normal kid, but without his upbringing he would have never been able to come to Hogwarts. He must have missed the kids' question because they were all staring at him expectantly.
“Could you repeat that please?”, the boy nodded and gave him a half smile,
“I was just wondering when we would start the lesson sir.. Since were 10 minutes into it already”, Dazai turned his gaze to the clock in the corner and coughed when he saw the time,
“Right sorry, Erm for those of you who don't know me as I am new. My Name Is Osamu Dazai and I will be your Potions Teacher during your time at Hogwarts, I expect you all to refer to me as Professor Dazai and nothing else, Understand?”, The children nodded and Dazai let out a pleased hum, “Okay now I advise you put your wands away as there is little use for them in the class, and many of you will hardly believe this is magic, and I don’t expect you will really understand the beauty of the softly simmering cauldron with its shimmering fumes, the delicate power of liquids that creep through the human veins, bewitching the minds, ensnaring the senses... I can teach you how to bottle fame, brew glory, and even stopper death—if you aren’t as big a bunch of dunderheads that is..”, Dazai applauded himself for remembering the speech Snape told him in First Year, but that lesson was just an entire lecture about safety and boring stuff, So Dazai grabbed one of the First Year Textbooks on the desk and turned to a random page, it wasn't necessary as he memorized the same book back in his first year but he needed to know the page number anyway, “Okay Students, turn to page 27 and we will start on one of the easiest and possibly useless potions there is, The Hiccoughing Solution, this potion causes hiccups so it's useful to those who want a bit of chaos-”, Fred flashed to mind, “-But deems Useless for those who are here to become greater things...” The students all turned to the designated page and began to go grab their ingredients as Dazai stayed sat down in Snape's chair, in Snape's classroom... It felt wrong.
[Time Skip: 6pm, Dinner in the Great Hall]
Dazai was uncomfortable to say the least, He saw no point in eating as it was but having to eat at the front of the hall he so much as hated whilst surrounded by people who used to teach him, minus the new defense against the dark arts teacher, and being sat Infront all of these noisy bratty children, god is this what Snape's internal monologue was like.
“Say Dazai how are you settling in?”, McGonagall asked, her voice slightly raspy with age. Dazai just smiled at her,
“Just fine, Professor McGonagall!”, Dazai rhymed back very sing-songly, McGonagall just smiled and took a bite of whatever food was set out Infront of her,
“You can just call me Minerva now Dazai, since we work together”, McGon- no Minerva stated and Dazai nodded and stared back at his plate, Would Snape be upset with him for not eating... probably, Dazai placed a sausage and some mashed potato on his plate, as he ate, he got lost in thought, an unneeded reminder of a memory hit him,
Snape bleeding in his arms down some random corridor, shooting can be heard from outside. Snape had a gun wound in the middle on his chest, it was bleeding too much blood, there was too much blood... Dazai's cheek felt warm and wet, but he wasn't bleeding... what was happening, was he crying? No demons don't cry, then Snape's hand went to rest on the side of Dazai's face and wipe the liquid with a smile,
“I-I don't think I've ever seen you show so much emotion...”, his voice was horse, shit shit shit Dazai couldn't lose Snape too. Why did it always happen, why didn't the grunts shoot him, he was the traitor. More gunshots went off in the distance, more yelling, Dazai heard dogs bark- Did Mori bring the mafia hounds to hunt down his scent... No, he could just set them alight, or-or send fill them up like balloons... Snape let out a cough and when Dazai looked back there was blood in his mouth, panicked he sat him up and patted snapes back as he coughed up the blood.
“Dazai-”, He turned back to snape to see him holding out some old notebook, it looked like Riddles Diary from Second year, “Leave the Mafia, become a teacher... replace me and become a good man, help out students like I helped you-”, he was cut off by coughing up more blood, “please...”
“Ho-how can you know I won't fuck up, how please... I-I-”, since when could his voice sound this desperate. More tears spilled from his eyes as Snape hugged him, he hugged him... H wasn't scared of him, he was safe, Dazai was safe, Shujji was safe...
“Because you're like a son to me, and you've said you can keep your promises...”, Snape hugged him tight and Dazai couldn't tell whether it was the blood from Snape's chest or his own tears that were soaking his face.
“I promise-”, and with that Snape took his final breath, Dazai let out more sobs and screams as he held Snape's dead body in his arms...
Dazai's pulled out of his thoughts by an obnoxious poke in the arm, Dazai couldn't suppress the flinch and quickly whipped his head around to see the New DATDA teacher grinning at him,
“What?”, he deadpanned staring at her grin, she looked only slightly older than him, 24 or 25 maybe,
“You were lost in thought... Also! Dinners over-”, as soon as she started talking Dazai was already annoyed, her voice was so high-pitched and annoying. Dazai quickly stood up which cut her off and made his way towards the Entrance of the Great Hall,
“Then why are you still here?”, he turned around and questioned, the eyebrow over his prosthetic eyes raised, before he was fully out of the too-big-for-its-own-good hall.
“Your eye intrigues me”, she pointed to her left eye, “it's so blue-”, Dazai cut her off,
“It's a Prosthetic”, he announced before leaving the great hall. He was glad she didn't follow him as he walked to his staff room. Could this school seriously not afford to go in rooms and at least remove all the previous owner's shit, not that he should call Snape's stuff shit, it's just everything he works and lives around now was Snape's. He moved into Snape's cottage whilst he was in hiding, and refuses to move out, his bedroom at Hogwarts was Snape's, his office was Snape's his classroom was Snape's... It feels disrespectful to call all these things his considering the belonged to the first person who ever saw him cry. Dazai lay on Snape's bed, in Snape's room, no this is my room and my bed now.... Dazai laid on *his* bed, in *his* room, that still sounds wrong... *Shujji* laid on *it's* bed, in *it's* room. No that was just wrong on so many levels... Dazai sat up frustrated and pulled the suicide note out, it was in case he gave into his desires one day... He read over it and realized that it was just one big ass apologies for existing and letting Snape down. He crumpled it up and threw it in the bin, and just decided to get some sleep, he’d need it to deal with those students.
