"If you had carried it around every day for ten years, you would be able to lift it too, Kami-sensei." Shira replied, thrusting it forwards so that she could take the massive weapon. If Kami's point was to prove that Shira was stronger than most people by virtue of being used to the weight, the method she was currently attempting was not going to be successful - holding Unmei no Chikara was not about strength of body. Holding the ancestral glaive was as much about knowing how to hold it as well as being used to its weight, it was about a deep understanding of the way in which they were forged and of the burden that you were taking up. To hold Unmei no Chikara was to hold the history of everyone who had ever held it before in your hands, to hold a weapon that had seen every war since the first, and to hold the legacy of hundreds upon thousands of people close to your heart. The Power of Fate was not something to be taken up lightly - something Kami would learn - but it would not prove her point. Wielding the glaive required knowledge and time, not something as mundane as strength.
"I was in the war, Kami-sensei. That is why I hold the title of Warbringer. Warbringer Shira, Master of the Flag. Please understand that I am confident in what I can do, and that I have used my skills in true war before - I am just more aware of my limits than others may be. The future is an unknown, so it is my responsibility to guide it towards the ideal. As a Warbringer of the Hataga, I am to ensure that my future is one of warfare, and in order to ensure that I must grow stronger. I must become more than I am, and that is where I am in need of you, Kami-sensei. As for Sai's family... That isn't something I have to worry about, Kami-sensei. My immediate family are dead, and the remainder of the Hataga are honour-bound to war - if I am to be killed by what I could call my family, it will be the purest death possible, and I will welcome it." Shira added, taking on a grave tone of her own as she did so. The pair seemed to be concrete in their beliefs, and while Kami was trying to impose her beliefs upon Shira, she did not have that authority, and she never would have that authority. She was not Bujin. Shira would obey her to the end, follow her every command, but she would never falter in her loyalty to everything that the Hataga were. There was no greater crime.
"A title and honour mean nothing to you because you have never had them, Kami-sensei. You do not understand what it means to serve. I will be what I am meant to be, for Unmei no Chikara does not give power to those who cannot take it. It decides my destiny as much as I do, and if I am to grow strong and masterful, then I will be. I mean no disrespect, Kami-sensei, but you are not Hataga. You cannot understand, not yet."
As she finished speaking, Shira dropped Unmei no Chikara down onto Kami's unstretched hands, giving her the weapon so she could feel its weight - it was not just a physical weight, but a metaphorical weight, and while she perhaps would not initially understand why Unmei no Chikara felt so heavy, she would do so in time - she would learn from it, and be its student, for destiny was the greatest teacher of all.
