>>49807351Her natural talent is to never give up, to care, to want to achieve. It's nothing shinny, but see where girls like shion, ayame and aqua are, girls with said "natural talent" but who don't give a shit. Absolute shadows of what they could've been if they cared.
Despite all of Koyori's lacking points she still holds on to the thing that she knows she's good at, and despite her "lack of natural talent" she has grow up an insane lot compared to when she started. She's a true idol: idols aren't the best dancer, singers, etc, but you still like them and support them. You want to see them achieve something, you want them to improve, and koyori gives a lot of that.
Her natural talent is something that looks simplistic and unspecial on the surface but as you grow old you realize it is the most amazing trait someone can have. There's nothing more valuable than seeing someone you care about being happy doing something they love.
