Subject: The weird letter
Konnichiwa.
You know about the letter I told you the other day? Well... it seems it was my father's doing. I even had the difficulty to believe what the reality showed me. I.. Everyone thought he was gone, but no. He told me what happened, but I think there is something else behind what he said...
If I recall correctly from your personal file, your father went MIA a long time ago. I believe this is good news then. Given the circumstances, you can take a leave to enjoy time with your father.
The reason for the re-appearance of your father might be not that simple, however. I have never had access to classified files detailing the scope of operations of the imperial Naval Forces from around the Nomad Wars but I did hear rumours. Heaven's Arch is an example of a place around which there is a plethora of stories of various credibility. What is certain that we lost there quite a lot of soldiers and some of them returned "different". Even Governor Tekagi suffered from an unknown affliction. The truth is barely discernable behind all the theories. At any rate, you should keep your guards up. Even if that is your father we are talking about.
Do not think I want to discourage your family reunion, however. It is possible that your father was transferred from the regular Navy to Kusari Office of Intelligence. If so, the secrecy of KOI at that time was justified due to Rheinland's aggressive movements and attack on New Tokyo itself. Why it was kept a secret for so many years, however, is a different question.
I wish you luck uncovering the truth. Please, use your time off the service for either spending time with your family or investigating the matter. Either way, this is your personal matter and it is understandable if you decide to keep it to yourself.
