However, she has her charms for those who see them and we must respect their earnest interest in her and her (possible) disability. We can't just disregard her completely. She is an original character the devs created and she was a success if we look at Shizune's path in Act 1 and consider her unexpected popularity among some folks.
Let's face it: discussing Misha's disability is way better than stating that Shizune is a tsundere, Hanako a moeblob, Lilly a perfect wife, Emi nothing more than a loli, Rin and Kenj are comic relief characters and then call it a day. THAT would cripple the characters!
So, I am really anticipating the next theory about Misha and searching said theory for any holes, it's like stealing candy from children.
