The Prince's Letters

Kazu has no memory of his past, living a life - and a rather successful one at that - as a free sword for his friend. The only thing he remembers is a little girl who calls him "brother". Try as he might, he can't figure out anything more...and yet...
And yet his past is the one catching up to him.
There's more to do with just a little girl, as he'll soon find out. The scandal covered up by the government fifteen years ago will soon be uncovered, sending perhaps the entire country through a dangerous war.
