Prologue
"So…this is your final decision?" a male voice asked sadly, his face obscured by long dark bangs.
"Yes." A calm female voice replied.
"Are you sure? Once you do this, you can't come back. We'll hunt you for the rest of your life."
"I've been planning this even before I got here, Isuku-sensei. I'm not going to change things now."
"…So you meant to betray us, all along." The man, Isuku, stated.
"…I'm sorry." The other voice muttered.
"Is that all you can say? Two years of friendship, of being your sensei on a genin team, and all you can say is 'I'm sorry'?!" Isuku almost shouted angrily.
"…I wish things could be different. But I have no choice in this."
"There's always a choice." He answered almost curtly.
"Not always, Isuku-sensei."
"Don't call me that anymore. The moment you step out of those gates, you and I are enemies. And you should start acting like it."
"…I'm sorry, Isuku-san…"
"Say that to your teammates. They'll be the ones to go after you."
"They'll never catch me, and you know it." She said; a trace of arrogance in her voice.
"Maybe; maybe not. But eventually, you'll get tired of this. You can't run away forever.
"..."
"I know you, Mitsu." Mitsu's face was sad as she looked at her former sensei.
"Not well enough, Isuku-san. Not well enough…" with that, Mitsu jumped away from her old sensei, and through the gates of Kumogakure.
