I tried it out, but you are really overhyping the complexity of the combat. For anyone wondering, combat goes like this:
Three Yokai are on the battle screen at any one time, with six total in your active party, and you can basically spin a wheel on the touchscreen to move Yokai in and out of battle at will. They attack on their own except for a special attack they can do. Everybody has one full charge for their special attack at the start of battle, and the gauge refills from normal attacks. There is a status effect called dispirit that lowers stats, and to take care of it, you just maneuver a Yokai out of your battle party, click "purify", and boom.
For the special attack and purifying, you have to do things on the touchscreen like "spin" AKA just draw circles quickly, touch dots, and vaguely trace shapes with at least being mostly in the lines, among other tasks depending on if you're purifying or doing the special attack.
Otherwise the demo doesn't let you explore menus or anything, so you're left in the dark on how stat progression goes and otherwise. Your Yokai start at level 10, and with no menu access, your team and settings are static.
If you just do the objectives, the demo is only about 15 minutes long. It's seriously short if you just run through it. To add length, you can explore the small section of town you have access to and find other Yokai that you can battle. Like in Pokemon, these random Yokai have a random chance of joining your team after being defeated, although you can't actually add any of them into your active party since you have no menus to use.
For other side stuff, you can catch bugs, and I suppose if you really want to, you can level grind a bit by fighting Yokai located in trees and bushes, as well as under vending machines, cars, and otherwise all over town, and that's pretty much it.
I enjoyed the demo well enough, but it was an exceptionally small taste of the full game. This didn't do much for telling me whether or not the game would be worth buying, which somewhat defeats the purpose of a demo.
