I think we are all his biggest شائقین cuz we all love him in our own way. Being the biggest پرستار of somebody isn´t a عنوان a single person could earn. It´s a عنوان for all those who really love this person with all their heart.
I LOVE HIM WITH ALL MY HEART!!!!!!!!!!!! I would love to be the biggest پرستار ever, but in my opinion everyone is a Fubuki fan!!!! Fubuki daisuki!!!!!!!!!!!!!!!!!
It would be a little selfish of me if I say that I'm his biggest fan. Fubuki would be disappointed If one of his شائقین have boastful fans. So to get that kind of honor, It would be a long time for me cause I need to work hard to prove to everybody in the whole world that I am his biggest fan.
But I love Shirou to all my heart, because of him I had gained many friends, others became very close to my heart. It's really hard to explain how I feel for him.. But I'll be working hard to get that title. ^^
He is my favourite Character! I love him the most, so I'm a big fan, but it isn't good to say that I'm his biggest, 'cause most of his شائقین would say that it is his biggest fan. No one can decide who is whose biggest fan
