Sothis!! but back when she wasn’t used for parts!!
Bonus with @exaltedgrimleal‘s help:

Really sorry for the delay. This chapter took me way longer to proof read and refine it.
Hey I just realise there is a FE Fates website. And a quiz for whether siding with Nohr or Hoshido
I apologise for the late update. This chapter kills me from inside.
Just started designing Underlying Leokumi for the fan book version released this summer!
I am currently thinking if I should sale it. Feel free to leave your comments/pm me

Happy Birthday, Felix! You fight good.
Chapter Summary:
The truth is always too heavy to bear.
No matter if it is the truth that Queen Mikoto gave up on saving Takumi, or the fact that I have always been pulling the strings, they are all too horrible to be true. Too tragic for that innocent child to witness. In this bloody world, such facts should never enter the ears of that kid. They should never be listened by the pure and innocent. They don’t deserve it - These tragedies should only be sighted by the ones who are responsible for it.
I tried to hide them. I need to hide them. But the more I do, the more it backfires. I would never forget those struggles - How much Takumi tried to escape from my grip when I killed that Hoshidan ninja. How he blamed me when he realised I have always been using him. I know, this time, I shall face the truth. I shall confess what happened to him. Yet, when I meet those amber eyes, my lips shiver, my eyes soften - They don’t deserve it.
New Black/White SRs are so strong. I’m crying...
By the way...
Drew King Leo not so long ago to save soul from CYL 4
The burning castle, the unending requiem. People screamed, as their bodies laid dead. I tried reaching out, seeking for help, yet none hold my hands - Mother has fallen, and Sakura is nowhere to be seen. The laughs echo, as the dusk engulfs the dawn, as the darkness overpowers the light. As the once peaceful kingdom has burned into ashes.
I hope it’s all just a tale.
