I guess Nio knows who to call when she can't make the deadline and needs help with the drawings lol
Sadly no. The chances of Touko and Yuu getting to do anything like this soon are astronomically low.
The chances of Touko being portrayed as just another Mei Aihara who does little else but be there, needing the girls in love with her to tie her laces as a matter of speaking, and being portrayed as melancholy and socially incapable on the other hand...
