Spoiler for LN:

Saten was not mentioned in LN, only in background of 2 illustrations -> so we know she will not die (or be crippled), but that's all, anything else could happen to her and still be canon.

As for Touma, he recalled all the "misfortunate" events of Daihasei after it ended, so if something happens to him and he gets involved, it would have been mentioned there, unless..
