Dear Ryouma,
My brother, I write this to you after awakening from a horrible nightmare. Please refrain from attempting to ingest your katana through your navel.
Love,
Kamui
Dear brother who forsook your birthright,
Go, Kamui, while you still can. You'll never beat me. Not in ten years. Not in one hundred years. Not even in one hundred thousand years will you beat me.
With honor,
Ryouma
