We can't control everything we do in life. That was the same case for you and your brother Giyu. When you showed off your water powers in the Hogwarts Express the others found out you had powers and they were impressed and you realized you'd be in trouble for doing so. You didn't know what your fate had in store for you but all you could do was just wait. It's been a few months now and you've started attending Hogwarts. You really liked it here, people were nice to you but never really seemed to leave you alone. They were always so protective over you and always treated you like some kind of kid which frustrated the hell out of you despite you being as level headed as your brother

Why, just the other day when you went to the Forbidden Forest in search of some unicorns since you've never actually seen one with your own eyes but unfortunately for you Fred and George were there at that time since they were looking for some herbs to include in one of their many pranks and they caught you wandering around the Forbidden Forest. "Y/N what are you doing here?'' asked Fred in surprise as you replied "I'm searching for unicorns. I've read about them in books but I so badly want to see one'' and George replied "Y/N it's not safe for you to be out here on your own. A lot of bad things happen here. From now on promise us you won't be out here on your own?'' and you promised. Just as you guys were about to go back to the castle you finally saw a unicorn and your eyes sparkled with excitement and you gushed "Oh wow, finally an actual unicorn!" Fred and George couldn't help but smile when you said that, you looked rather endearing and adorable. The way you smiled was really cute, they promised themselves that they'd protect you and your smile at all costs no matter what

Of course when you went back to the castle you were immediately lectured by Harry, Ron, Hermione about the dangers of the Forbidden Forest. Then Malfoy got to know as well and he cornered you as soon as Transfiguration class was done and he spoke "Y/N why in the name of Merlin would you go into the Forbidden Forest?'' and when you revealed your reason he actually hugged you and told you to never do something like that again and if you wanted he'd take you and made you promise not to go anywhere without telling him first. You were surprised with the way Malfoy was acting, why was he acting so strangely? You didn't have time to deliberate further on your question though because Harry, Ron and Hermione came looking for you. They just glared at Malfoy when they saw him hugging you

"OI! SHOVE OFF YOU GIT!'' yelled Ron in anger and you looked startled and a bit scared as Malfoy snarled at him and they were about to have a duel but luckily you managed to stop them in time with your water powers by splashing them in their faces. "Unless you guys don't stop fighting with each other I'm not going to talk with you anymore'' you huffed in anger and went off. "This is all your fault that my Y/N won't talk with me now'' and Harry snarled "I'm sorry, since when the bloody hell was she yours?" and Hermione replied "Just because Y/N hugged you back that doesn't mean she wants to be with you'' to which he replied "No one asked you for your opinion you filthy little mudblood!'' and they were pissed at each other and felt bad that you were no longer talking with them

Sure enough you were sticking and abiding to your promise when you ignored them the next day. Harry felt miserable, Ron felt like his heart was breaking and Hermione felt ready to cajoling you into being on speaking terms with her. Draco was livid because of Harry, Ron and Hermione's interference when he was having his moment with you and was ready to do anything to make you forgive him. Meanwhile you were missing your family and your brother Giyu. Each night you'd look out of your window with a sad look, wondering if your brother would come to rescue you and take you back with him. Did he really care so little for you that it's taking him so long for tracking you down and getting you back? You'd think about it till Ginny would ask you to come back to bed. She didn't want you spoiling your health and when you tell her you can't sleep she'll talk with you for a few minutes and slip in some herbs in a glass of milk to make you fall asleep. She doesn't like it when you're sad, you deserve to be happy and enjoying things around you

You didn't know your brother was working relentlessly day in and day out to find you. Most people would have resorted to a state of helplessness and being unable to do anything but Giyu was mentally strong and was hell bent and determined to find out where you were no matter what. He'd ask nearby villages if they'd seen you, ask the people living in his village if anyone's seen you, scout the woods for you and he didn't give up looking. Giyu already lost his best friend Sabito and he wasn't going to lose you too. He had to get you back no matter what. Giyu would search the skies and the grounds to find you and wouldn't give up, it would be only a matter of time before he finds you and reunites with you. After all patience is key

Another person whos' learnt patience is key was none other than Voldemort himself. He had to bide his time till he got his hands on the boy who'd always thwart his plans, Harry Potter. As time was passing, he was getting more frustrated and angry. Harry Potter was still alive and it looked like witches and wizards of the Wizarding world forgot just how strong and fearful he was. When he heard about you through Lucius after reading Draco's letter about you, he was quite impressed with you and your powers. He needed to have a useful and powerful ally like you on his side so he could take down Harry Potter for good and conquer the Wizarding world once again just like he did in the past

He instructed his Death Eaters to capture you and bring you to him but you shouldn't be harmed at all costs no matter what. Bellatrix was curious, who exactly were you and what was so interesting and special about you that the Dark Lord himself took such keen interest in you, she had to find out for herself. Lucius thought you'd make a very good companion and spouse for Draco and was eager to meet you as well. There was a slight problem: They couldn't just barge into Hogwarts and kidnap you, there was security all around and besides, Dumbledore and the other professors would most certainly keep an eye on you and look out for you because of your powers. They had to take you some other way

Luckily they got a golden opportunity to take you when you were visiting Hogsmeade during the evenings. With no one else with you, Bellatrix couldn't help but think you were silly to wander off alone like that. You reminded her of a sweet little lamb, lost and all alone in the midst of predators. Bellatrix disguised herself as someone you knew with the help of the Polyjuice potion. She lured you away from where there was a lot of crowd and she put you to sleep instantly with her wand as she apparated back with you to the Dark Lord's place. When you woke up you were obviously scared out of your wits end. It's not everyday you get kidnaped by the most feared wizard

Voldemort asked you to join him and told you he was really impressed with your powers but you refused to join him. Fenrir Greyback was about to bite you for being so disrespectful but Lucius wasn't having it. He silently thought of a curse and sent him flying back as he hissed and snarled with rage and Lucius pretend his wand malfunction for a few moments and the others in the room just looked plain amused. Voldemort told you that you'd be here for a while unless you changed your mind and you replied "I don't care, I'll still escape one way or another''. He just smiled at you in that creepy unsettling manner and locked you in a room with no windows and your wand was long confiscated by the Death Eaters and it wasn't like you could use your powers as well since he cast a spell on you to prevent you from doing so. You really were in danger this time

Fortunately for you, your luck was good that day because you heard some commotion going in the other rooms and you pressed your ear closer to the door to listen to what was going on. There was lots of yelling, chairs being hit and thudding on the floor and water seeped in through the door of the room you were currently in as you stood back in fear wondering what it was. The door suddenly burnt to ash and in front of you stood someone you thought you'd never see again. It was none other than your brother Giyu and you were unable to believe your eyes. However you also needed to make sure he wasn't someone else in disguise

You asked him to tell you something which you've told him in private and when he revealed it although a bit confused as to why you'd ask him to do so, you ran to him and hugged him. You then explained the situation to him and greeted the other Hashiras around you, Rengoku, Mitsuri, Obanai, Shinobu and Tengen. Sanemi, Gyomei and Muichiro couldn't come since they were stuck at headquarters and were also on the lookout for you, in case you'd show up there. When you asked your brother how he found you, he replied that he was fortunate his master Kagaya Ubuyashiki finally saw you in his vision and here they were ready to take you back. The joy was short lived since the Death Eaters were back again and they weren't going to let you escape so easily. Giyu told you to stick by his side no matter what as he fought with the Death Eaters

After Voldemort had to retreat and vanished into the air, you wanted t go back to Hogwarts to say goodbye to your friends and professors as they agreed and waited for you outside the castle. When you were busy saying your goodbyes, Harry, Ron, Hermione and your other friends thought you were kidding till you made it dead serious you weren't. This was the only time all the students from the 4 houses decided to cooperate with each other and they obliviated your memories so you could stay back with them permanently. As for your so called brother and the other people with the superpowers, the professors could take care of them. You were destined to stay at Hogwarts with them for good

I hope this was okay, I'm usually no good when it comes to writing for crossovers TvT
