Scrap Paper[]

A scrap paper can be found around the map, when put together it form a letter written in Japanese by the original timeline's Takeo Masaki to the Emperor, detailing his experiences at Division 9's island facility. The letter, translated into English, reads as follows:

"To my beloved Emperor,

It has been several months since I last received orders from you, and I cannot help but say that I am at my wits end.

Since I landed on the island, I, your foolish servant, have continued my inspection and recording of Division 9's activities. However, despite being directly dispatched by you, they regard my work with suspicious eyes. As such, I have been barred from, and forbidden access to, almost all research areas.

The situations continues to worsen. The installation commander ordered me to hand over my weapons for the duration of my stay. If he hadn't shown me the relevant papers ordering me to comply to maintain security, marked with your signature and seal, I would no doubt have objected. I have never raised any doubts whatsoever concerning your judgement Sir, but I am concerned that these circumstances may prove a great hindrance to my mission.

I understand how important the alliance is for our righteous cause and final victory, but the influence of the German operating force "Group 935" has become increasingly worrisome. Over the last few months, the number of officers they have here has increased; I cannot help but think that it is they who are propelling the plan.

Judging by what I have seen, the research done by Division 9 has been far beyond acceptable. In fact, their aberrational methods of weapons research can only be described as "abnormal". Not only do they use prisoners of war for living-body tests, but they have also been trying to control the supernatural powers of Element 115. I therefore think that if we permit them to continue their work, dark clouds may soon loom over our great country.

I, your foolish servant, will continue to watch them, and will report to you whenever possible. If the idea so pleases you, I think it is necessary that you intervene directly in order to for us to better understand the aim of Division 9's research, and make clear the ramifications of their plans.

I hope you receive this message.

Your humble servant,

Takeo Masaki."
