Dearest Haruka,
It is me, Koa. I'm writing you to inform you that I needed to seek out my husband and make sure that he was safe. Things have gotten a little crazy, and I'm quite terrified to be honest. Right now, I'm on my way to Moon Country so my stomach is in knots. I decided that I wanted to protect those precious to me and that's my family; you, Keita and Onamuji. I'm going to stand by Onamuji's side to protect him, to protect you, from this vile poison that exists in the world... I'm imploring you, sister, there is a man called Miroku Akkuma - he's toxic and needs to be disposed of.
I'm travelling to this country with the intention to kill him. I don't know if I am capable of such a cruel thing but this needs to be done, I know that much, because I cannot allow his existence to even threaten my family. Iwagakure is corrupt and you can't trust them, at all. Akkuma seems to have some relationship with Hissori, the Medical Chief, and also the Guardian known as Kurayo. I want to protect you and I will do this, from the background, please keep yourself safe and sound.
I'll keep writing to you, Lady Haruka. My loyalty is with you and my husband, I know this makes things difficult and troublesome, and believe me I know it's conflicted.
Whenever you are free to meet me, I'll do my best to see you and beg for my forgiveness. I hope I haven't disappointed you too much, Lady Haruka. I should be safe with Onamuji, for now at least. I'm scared but I need to do this.
I'm sorry.
I'll be in touch soon.
All my love,
Koa
