You've probably noticed I've been skipping over some details and adding in some details that may or may not be cannon (I don't really know). There are reasons for that. This story is mostly about Harry getting stronger and…slowly becoming somewhat psychotic? Eh.

I'm thinking I might try writing another Dark Animetopoeia. A lot of this stuff was writing a while ago and I'm definitely a better writer now.

By the way, make sure to check out Magical Girl Animetopoeia and the original Harry Potter and the Animetopoeia.

Without further ado, the disclaimer:

The Reaper was taken away by the government. He was probably going to be in prison for a long, long time, seeing as he'd basically gone rogue.
"Oishii!" Irena gasped out as she ate the cake.

"You guys all made this?" Irena looked at them all.

"Well…" Nagisa trailed off, "We helped, but it was Harry's recipe. He did most of the work."
"Eh? Uso." Irena looked at Harry with surprise, "You can cook too!? What can't you do?"
Harry laughed,

"Well…I'm pretty sure you can do more than I can, Irena-sensei."

Irena blushed a bit. She looked away, then suddenly took another bite,

"So tasty!" she said suddenly.

The other kids laughed, some of them took a bite of their own pieces of cake.

"Umai!" Karuma said, looking surprised as well, "You'd make a wonderful housewife, Harry-kun."
Harry gave him a dry look. He knew he was trying to rile him up…just as he always did…with everyone.

They were all none-the-wiser about the Reaper or what had happened to Harry and Irena. Neither of them had told anyone.

November came around as did their career surveys. Apparently, all Japanese schools had these. Some high schools specialized in certain subjects, so if you wanted to follow a certain career path, it all started with which high school one wished to go to.

Harry stared at his paper. He'd never really thought about what he wanted to do when he was grown up…So far, his plans consisted of defeating Voldemort and then…what?

He was a killer. His path so far was the path of a killer. When it came to schools though, he might be traveling to a new dimension once again…

The next day, the students were all called in one at a time to discuss their career options with their teacher.

Koro-sensei was giving the advice.

"Ah, Potter-kun, take a seat." He offered.

Harry closed he door then moved over and sat down across his teacher's desk.

"Now then, Potter-kun…do you have any idea as to what you want to do when you grow up?"
Harry looked down uncertainly,

"No…I mean…honestly, I never really thought passed bringing down the person behind my parents' deaths. I came here…to Japan to learn how to be a killer. To learn how to do that…and then I entered the assassination class. I didn't know that was going to happen." Harry furrowed his brow, "If I survive to be an adult…I never really thought I'd live this long to be honest."
He was supposed to die once he turned seventeen. He was sixteen now.

Koro-sensei was silent a while, waiting for him to say more.

"I'm planning on moving." Harry told him, "Once the school year is over…I'm going to find somewhere else to train. That was the plan. Staying in one place for too long is no good for me. I know this doesn't sound particularly good, but I did consider a career as an assassin."
"Oh?" Koro-sensei regarded him curiously.

There was no judgement there. That surprised him a little.

"You certainly have the talent for it, Harry-kun."
He'd used his first name this time. Harry looked up at him.

"But talent can be used for many things. I want you to keep in mind that we always have choices. The decisions of others don't matter when it comes to this. You don't need to do what everyone is pushing you to do. You don't need to become an assassin because you believe you have no choice, because there is always a choice available to you. Always."
Harry drew in a deep breath,

"Yeah. I guess there is. I still don't know which country I'll travel to next." He looked down at his lap, "Believe it or not, Koro-sensei…everyone wanted to protect me. They tried to hide me away…but they didn't do it right. Every time I was hidden away, someone would try to kill me and I was left to fend for myself. In those moments…they'd all either run away or say I was being foolish when I tried to ask for help. When I asked for training at least, I was patted on the head and turned away…I was scared."

Koro-sensei looked like he'd softened a bit at the confession.

"I realized…when I was eleven that I either needed to learn how to defend myself…or I'd die. Those were my choices at the time. So…I studied. I trained myself as best I could to fight. I was terrible. I couldn't do half the things I can do now."

Harry's eyes dimmed,

"I know that…I can keep running away from my past, or I can return to Britain and face it. I can chose to see my friends again and keep dealing with the threats to my life and put my friends in danger, or I can strike them and dismantle their organization until there's nothing left of it." Harry paused, "I guess…I could also settle down somewhere, get a new identity and live a semi-normal life…it's not like I don't have the funds…But…" Harry looked down again, "I remember."

He clenched his hands into fists.
"I remember my mother dying. I remember her being killed and…I don't want anyone else to have to see their own mother being murdered in front of them like that. Not because of those people…You're right." Harry said, looking back at Koro-sensei, "It's my choice…and I choose to go back someday and stop them. I'll pick up where my parents left off and dismantle the Death Eaters until there's none left."
There was a silence and then…

Tears and snot started to flow. Koro-sensei dabbed at his face with his handkerchief,

"H-Harry-kun…"
"E-eh?" Harry was taken aback by the emotion he was showing. He felt his face head up, "I…I guess I made my decision…Thank you for helping me, Koro-sensei. You've given me the training I need…not just to survive, but to accomplish that goal…Er…" He shifted awkwardly, "Thanks."
Harry had never been one to display a lot of emotion. Tears and happiness weren't exactly encouraged in the Dursley household. All he'd been shown was anger. Red, hot anger by his relatives. It was what he'd grown up knowing.

But…after spending time in the E-class, he was slowly starting to break that habit.

Anger was a powerful emotion…but Harry was starting to grow tired of it. His relatives were always angry and…he was just tired of it all.

He hadn't realized how tired he was of it until he'd come here.

No death threats, no obnoxious bullies. No one trying to hurt him. No one saying how much they hate him.
Sure, there was a lot of danger, but…

"I've learned a lot." Harry said, "Thank you."

Exam time came up. All that studying was harsh and a little confusing. Harry had managed to absorb more knowledge than he'd thought possible. All the students taught their best subjects among their classmates. Harry's best subject happened to be a tie between math and English, so he got to teach both.

Gakushuu Asano, the principal's son stopped by, begging the E-Class to end the whole educational values clash between the principal and Koro-sensei. They all agreed to do their best.

Who would have thought that education was so competitive? It made him think of Hermione actually…although Harry doubted even she would be capable of competing with Karuma.

Apparently, their exams were so advanced that most, if not all of the stuff they were learning was found on the entrance exams to the average Japanese university.

And yet…Harry took to learning it with ease. He'd never had a teacher like Koro-sensei before. He was just…that good.

Exams came and their first test was English. Harry made it through the whole thing…barely. Everyone else seemed hopelessly tired after words. And that was only the first exam!
The vocabulary used was something Harry wouldn't expect to find on an exam in the average English-speaking school. It was kind of ridiculous, really…

Then came Japanese, Harry's worst subject. He hadn't managed to finish, making it only six eighths of the way through before time was called.

Apparently, he wasn't alone though.

Their last exam was math. Harry worked through each problem relatively fast. He didn't have time to focus or think about anything else.

The last question was the trickiest. He wasn't even sure where he was supposed to begin…Well, if he just used the right equation, he could still get partial marks. Still, he'd been hoping that he'd be able to do it all the way…

Wait, he paused a moment, rereading the question. There was a line at the top that suddenly made things clear.

He quickly wrote down the answer and was left staring at the sheet puzzledly.

He was starting to second guess himself. Was it really that simple?
"Time!" The teacher called.

No time to review. Well…he'd have to find out later if his method was right or not.

…..

About a week later, they got their results.

"Now then, everyone. I'll be handing back your exams." Koro-sensei told them, holding folders in his tentacles, "Did your second blade manage to meet it's target, I wonder?"
Everyone waited with anticipation.

He lifted up the papers,

"No grumbling about missing points here or there now."
In a flash, Harry suddenly had the papers in his hands. Everyone did.

"Were your scores this time good enough to get you into the top fifty overall?"

Harry swallowed hard, looking down at his exams. He hadn't ever gone to a normal school after elementary. He was worried he might have held them all back…

His face slowly lit up when he saw his results. A one hundred in math and English! Both of them! Ninety-one in history…ninety in science and…eighty-one in Japanese.

Those were good grades. Really good grades. Those were like, Hermione-ranked grades. He'd done better in Japanese than he'd thought.

Koro-sensei was standing at the front of the room now.

"The main campus will be posting the overall scores right about now. So, let's start with ranks here in the E-Class too."
Everyone stood up as he unrolled the poster which showed their rankings. They all stared, trying to find their names on the board.

Harry spotted his name immediately. It stood out as it was the only one in katakana.

He'd made it.

He was ranked number twenty-one.

He felt his mouth fall open slightly. He'd managed to beat most of the kids who had spent their whole lives in regular school…

He felt a smile form over his face.

"I-I…" Terasaka spoke, "I'm number forty-six?"

Terasaka had gotten the lowest scores in the E-Class…which meant that everyone had made it into the top fifty.

Karuma was number one, having finally reclaimed his place at the very top. He got a bit of teasing from Koro-sensei after that.

Everyone cheered, throwing their exam papers into the air. Harry held onto his exams though.

One never knew when they'd be important, after all.

Well…not only that, but he was actually really proud of them. He'd never really felt a sense of pride over his grades before but…somehow, his attitude towards education had changed. Something even Hermione hadn't managed to change before with him.

Harry had discovered that he was actually smart. Really smart, especially in math.

It would have been nice…if his parents could see this. Maybe he could visit their graves when he got back. He'd never been there before…but he'd want to show them.

He laughed a little.

"So…I have the grades and education to get into a Japanese university. I'm fluent in the language, by the way. I'm number one in my school at math. Well, I'm tied at the number one spot, actually."

It was kind of absurd, actually. Not long ago, he wouldn't have thought even Hermione would be capable of something like that.

Harry had never been told he was smart before…now he knew that he was.

The next day, the principal (being the sore loser that he was) tried tearing down the E-Class building. He threatened to fire Koro-sensei unless he wrote the questions in the booklets he lay out…and he put grenades in them.

Koro-sensei was blasted on the first one, but he quickly answered the others, leaving only one behind, the grenade the principal was to trigger. And he did, much to Harry's surprise.

That should have been suicide…but Koro-sensei saved him by shedding his skin.

The principal, having been beaten, finally made amends with his past and relented that perhaps his methods weren't right (no duh. Most of the A-class now acted like zombies).

He left, a bit more life in his eyes than when he'd arrived and attempted to kill Koro-sensei.

….

Not long later, there was an explosion in the storage shed. Harry figured it was probably another assassination attempt…Huh. Strange how assassination attempts had become regular occurrences, but in a different way from how they had before in his previous life at Hogwarts.

They all ran outside to see Kaede. Her hair was long and out and she was standing on the roof. Green tentacles moved around her, coming out of the back of her neck.

That was like…Iruka.

Harry tensed, really hoping that this didn't have anything to do with Shiro…again.

"She would have had to have been in hellish pain." Iruka said once she had run off.

Kaede had promised she'd return later to kill Koro-sensei for good.

There was a lot going on and now…people were starting to wonder about Koro-sensei's past. Kaede had accused him of being a murderer. That didn't surprise Harry though. Koro-sensei knew a lot about assassination. He talked about it all the time. Harry had nearly taken it for granted that he was likely an assassin himself.

Maybe they'd finally understand why he wanted to destroy the world.
