I open the letter and go to the corner so nobody can take a peek at the letter since there are so many students are walking by in the hallway. I unfold the letter and it's her personal contact, I just realize that I don't have her contact and it seems that she wants me to contact her if I need some help. There's another thing in the letter, she said that she will try her best to capture them and it seems that the whole unit will be taking part in the war to get some kind of information and evidence to arrest these yakuza families since this opportunity won't come twice.
