Senior Brothers are Coming...

In a dark room, the only illumination in front of a white-haired man is that of a computer monitor screen, a program with a call. The other users' name is shown in several boxes with capital letters accompanied by a number on the screens.

The white-haired man, with a patch over his left eye, brings out his right eye purple with magenta sparkles, is frowning.

"Are you sure the decoded message is from her?" asked the man with the patch.

"P5, I could identify her initials E12. She was the one who sent it, and with the Master's signature as well. She is the only one who can use it." Replied the person on the other side of the computer, and the G6 box lit up as he did so.

"G6, is that right? Did she finally communicate with us? Does that mean she remembered everything already?" B4 asked in a sped-up manner.
