Like the title says. This impoves the Easiest difficulty TAS by nearly 5 seconds, mostly (if not entirely) due to the harder/smarter AI tech rolling more often. This is specially notable with Shermie and Miss X. The rest is more of the same except for some more annoying, smarter AI from Shiki and Whip, who were not cooperating that much, having me to adjust the combo for them specifically. Leona was kind of the same, but it wasn't as bad. Shiki and Leona have slightly lower health for some reason so I can go for a slightly faster finisher. I get an item reward after the final match due to the higher difficulty.
In retrospect, the general strategy and move inputs are almost (and in some instances, completely) identical to the easiest difficulty, save for some mild annoyances in a couple of fights. That whole dialogue thing is still stressful but at least this was a faster TAS in the end...
