The real issue is, finding her AFTER you've collected enough scrolls...

and when you do find her (and have enough AS for her), there is no guarantee your skills will all activate appropriately. While collecting 1500 scrolls total, I enountered Shuten three times (I didn't have enough scrolls or AS for her then, so I opted out of fighting her all but once). After I finished collecting that many scrolls, I couldn't find her within the last 9 hours (and I spammed about 20 remedies in addition to the waiting time). When I finally did encounter her just a few minutes ago... ... ... only one of my daemons activated its skill (and I only need 2-3 to beat her)...

so it's really luck based. I suggest that if your wg encounter rate is decent, don't bother fighting her for scrolls, because it's a waste of AS (and thus time) if you lose (vs. a sure win against the lower defense wgs). At least (for me), it takes 170-180 AS to defeat her, and that's a reward of 30 scrolls. Pouring Rain only takes about 60 AS for 10 scrolls, and Romeo/Juliet/Hayate take about 90 AS for 15 (though sometimes I lose because I'm lazy about redoing my team and stick 3 WWs in there >.>). Bonnie takes 120 AS for 20 scrolls. So it's about the same amount of scrolls as beating the lower daemons, and (pro) all in one go if you defeat Shuten, but (con) it's hard to beat Shuten and thus get those scrolls.

If she is available in SoSD, she'll be much much harder to collect talismans for, so if you're patient (and lucky) I suggest going for Shuten now.
