All his life, he had known that this day would come. His mother had told him, in her brief coherent moments, that it was his destiny. His grandmother, who seemed to have a stronger connection to reality, had elaborated. It was the fate of their family to find the one person who would complete them. Without this true love, they would feel empty and apathetic, unable to feel normal emotions or care for the trivial matters most people went through their lives taking interest in. But once they found their beloved, they would feel a powerful desire to be with that person. Their soul mate would be their only interest in life, and they would do anything to be near them. At any cost. If ever anyone came between an Aishi and their beloved, they do all that was in their power to eliminate them.

When he was very young, Eren had fancied that this was just a fairytale, another story of perfect happiness and love that didn't really exist. He definitely hadn't related it to himself. His life wasn't empty, it was just dull and miserable. His mother, heavily medicated after her repeated attempts to take her own life, was seldom permitted visitors at the ward. When he had tried to see her, she didn't often recognise him. When she did, she would hold him painfully tight and sob something about 'Senpai Taro'. His grandmother, who he lived with, was... alright. But there was something off about her. She was deeply absorbed in his grandfather, who she talked about constantly, but the rest of the time, the light inside her seemed to fade, and she would become distant. Unless she was telling him this story of love. As for his grandfather... his mind seemed to be getting weaker. He had retired shortly after Eren's birth, and now he sat in his armchair most of the day, muttering about 'mistakes'. Some days were brighter, when Uncle Budo and Aunt Hanako would take him out. He looked up to his cousin Hanado, who was strong and bright and full of life. She seemed to have fun effortlessly, and he wished he could be like her. But his grandmother didn't want him to have much to do with his father's side of the family, and the visits slowly petered out.

It wasn't until he was older, in middle school, that he understood. The story was true, and his poor, devoted mother had been driven to madness when her high school sweetheart, his father, had unexpectedly died just moments before his birth. She had fought hard to win his attention, and they had finally married. Both had been blissfully happy, until a heart attack claimed his father's life. Grief-stricken, his mother had tried to kill herself several times before she had been hospitalized after her best friend found her. Fortunately, he had been an infant at the time, and didn't remember the tragedy, but had his mother's friend not arrived when she did, he may well have starved and been another victim of it.

As it was, there was merely a long battle over his fate. Hanako wanted to raise him, in memory of her brother, but his grandmother Ryoba had returned suddenly from America, swept up the grandson she had never met in her arms, and insisted he was hers and hers alone.

And she had raised him to know his destiny was a love as passionate as the source of his mother's insanity. She quizzed him relentlessly, every day of his teenage years. Had he found the one yet?

So far, every day, he had shook his head. There was no one around him he had any interest in. The only emotion his peers engendered in him was jealously. He wished he could be normal like they were. But today was his first day at his new high school. His grandmother had enrolled him in a prestigious local school on the basis that she had met her husband there, and his mother met his father there. It must be a magical place, she had reasoned. Hanado had enrolled as well, because Hanako loved the nostalgia of the idea.

And now, standing on the pavement outside the school with his cousin, he could see her. Amongst the bland idiots who gathered around the gates and chatted meaninglessly, stood the most wonderful girl he had ever seen. She had pastel purple hair, an amazing figure and a way of just... being that seemed to light up the very air around her. He was vaguely aware that Hanado was talking, but for once he couldn't care less about his cousin. He had found his beloved, his destined one, his Senpai.

Now all he needed to do was make her his.
