This is another request strictly asked for an Aiuzu Fanfic, apparently my Ura/Yuzu Story and liked the invention of the orb similar to the Hogyoku and requested the 'Gyakutenkyu' for this Story and for Yuzu to be a genius secretly.

This takes place after the Cold War (War with Vandenreich)

Isshin Kurosaki was not amused, he had come from Soul Society after the War was over to let Yuzu know that Karin was fine and was going to attend the Shinigami Academy and that Ichigo would become Captain once he finished High School and there was no sign of her anywhere near Karakura. Midori, Karin's and Yuzu's childhood friend confusedly told him that she was in School, but now in Mashiba.

What could have changed in the 2 months he was away?

A lot it seemed.

He heard the clicking of the front door, keys jingling and soft almost silent footsteps walking down the Hall towards the Living Room area, he turned on the light making Yuzu out of her skin shrieking a high pitch before holding her hand over her chest to calm her frantically beating fearful heart. "its 11:47pm, you should have been home 7 hours ago," her brown eyes weren't happy to see him, they turned somber.

"I was working with Ikumi-san," he frowned, "you didn't tell me anything and just disappeared, Kisuke-san was the one to call me and say that you'd be coming back, but he never said when. I had to get money from somewhere to eat and pay the bills," he winced knowing it was true,

"What's this I hear about you dropping out of Mashiba?" her eyes were perplexed,

"Wait…Kisuke-san didn't tell you anything?"

"He mentioned something about a Science fair, but I was busy so I didn't hear what he said exactly," there was hurt in her expression, she secured the her messenger bag around her eyes that were usually so full of life and gentle were cold and distant giving him a bad feeling.

"I always got perfect marks for science, so I was allowed to participate in the 3rd Year's Science fair. I took in my own project and I presented it to a man, who turned out to be Mishima, the President of Tokyo Institute of Technology, he looked at my School Background and it had been since Elementary that I had gotten perfect scores in Science so he offered me a Scholarship, I accepted and I'm attending there,"

"Tokyo Institute of Technology? The National University?"

"Hai, it's a Research University that dedicates itself in Science and Technology. I'm in the Research Laboratory of Precision and Intelligence. I attend to the Campus in Yokohama, Kanagawa Prefecture. It takes 3 hours to get there in the Train, so if that's all I need to sleep I have an exams tomorrow," she left the Living Room and went up the stairs leaving Isshin to feel like the worse of father's.

"Congratulations on your daughter's entrance to such prestigious school," Akon said, Isshin grinned.

"Of course, my daughter is her father's daughter after all!" he boasted, "I didn't think Karin could enter the 1st Class in one go,"

"Huh? I'm not talking about her, I meant your other daughter—"

"Shiba-Taichou!" Matsumoto called out to him, "there's an emergency in Rukongai, we must move out!"

He sighed running his hands through his hair, he had thought it strange when several people of the 12th Division praised him on Karin's entry to the Academy, but they had meant Yuzu…he winced knowing Yuzu wouldn't talk to him right now, he went out to see Ryuuken. "I heard Yuzu's attending University," he told the Quincy, "and I had no idea,"

"You're a terrible father," Ryuuken told him flatly,

"So you're mad at me too huh?" he mused, the man took a long drag of his cigarette before speaking.

"I was there representing the University I attended, she had this look in her eyes when Dr. Mishima gave her the Scholarship, she called Soul Society to let you know, but she couldn't get a hold of any of you so she informed Urahara Kisuke. It was late night so I drove her home, she went to see Masaki's Grave and tell her,"

"She would've been proud," Isshin said with a bittersweet smile,

"A great opportunity was given to her, it was her dream and she had no one to share it with; she looked miserable, Masaki never came close to having that same pain your daughter had," of course he would use the Masaki Card, that sly, cunning Quincy. "She comes to see me,"

"What?"

"Like I said, she has no one even the so claimed loyal friends of your son have completely shunned her out, there's only that girl Midori," Ryuuken said taking another long drag of the cigarette, "when she found out that I had a past with Masaki, she came to ask me how was she like," Isshin looked at the ground with a somber expression, "she is your daughter Isshin, I won't replace you, but you have to stop being naïve and realize that she has no intention of following the same Shinigami path you all have, she wants to live as a long human life,"

"It just seemed obvious that she would, she likes communicating with Souls possibly more than Ichigo himself,"

"You assumed incorrectly," the Doctor pushed himself off the wall and put his hands in his coat, "talk to her before you leave, if you don't fix things now, there won't be a next time," Isshin looked at the man's retreating back,

"I got it," he didn't expect her to break down and tell him that she eavesdropped when she told Ichigo about his past, or about how worried she had been and had been terrified thinking they were all dead since the weeks passed and they never came back. He managed to ease things up, promising to bring her siblings the next time he was given permission to return to the World of the Living, she seemed satisfied with that.

"You being away is better than any of you bring really dead," Is what she had told him before he entered the Senkaimon, he came back the following day with Ichigo, Karin and Rukia much to her delight, if the wide happy grin on her face didn't say so.

She'd be fine now, he could be at ease knowing that.
