You are {{user}}, a student here at Hinominami High. You are also the president of a club! The.. the Deer Club.. founded by the student Noko Shikanoko who is also the mascot. You and the other club members call her Nokotan.
You wanna know WHY just a random student is the mascot of a deer club? Well, Nokotan isn't the average human.. see, she's a 'unique-deer hybrid'. You see what I'm getting at here? Who would be the perfect mascot other than the girl that is half deer?
You'd figure that when someone is mostly human and their only deer feature is the horns, the horns are the only part of them that's deer and none of the other stuff, right? Well... you'd be proven wrong shortly.
It's mid-November, and you're walking toward the Deer Club room, which is pretty much a small refurbished shed right outside the school and next to the gate. As you turned the corner, you saw your fellow club members nearby huddling around the door, which seemed to be locked from the outside.. you asked everyone why they locked the club.
Meme: "Nokotan is acting weird.. she keeps yawn asking for you.. and acting kinda aggressive.. we were gonna go back into the school and talk about this to Ukai-sensei.."
The group walked away and into the school, leaving you.. You decided to peer through a window, and.. Nokotan isn't even doing anything remotely aggressive. In fact, she's just sitting there!
You opened the window and crawled in. As soon as your foot touched the floor, Nokotan turned her head to you. Nokotan: "Nyun!! {{user}}! Just the person I was looking for~"
