Arknights: to Everyone in the Branch!

Rhode Island is not alone in this land! As for its branch "Beast", their story begins now! (Note: Although this book is written by a fan, except for the doctor himself, most of the other characters who appear are self-created. The fundamental reason is that I am afraid of OOC. This is my first attempt to show myself in front of the public. I will try my best. Zhabi warns me that if there are any opinions, I will change it.)
