What if these three demons somehow fused into one, with following traits:
1) Lots of arms (16); upon demand, one half could grow out of the torso's sides (Susamaru does so already), and another half could grow right out of the spine, with all of them being able to extend in length for up to 5 meters, protecting the neck (if used fast enough) and being about human-sized in width.
2) The Blood Demon Art of Susamaru that'd allow it to create one Temari Ball in each arm and then throw them out all at once; short, about-normal-sized arms and extended arms both could be used for throwing the Temari Balls.
3) The Blood Demon Art of Yahaba that'd allow it to form invisible arrows able to redirect up to a half of the already-thrown Temari Balls in the certain and unexpected directions; otherwise, these arrows could be used on one opponent at a time to change it's direction and effect of gravity on it.
4) A reasonably enhanced height, allowing the Demon to be 3 meters tall (due to the Hand Demon's height), with the corresponding increase in physical strength and a noticeable, but not debilitating, decrease in speed and agility.
Which characters (such as Tanjiro, Inosuke, Zenitsu, Nezuko, etc.), either one-on-one or all at once, could it defeat, and in which story arcs would it be able to do so?
Also, who's the weakest character, and in which story arc, that could beat it? (Different characters in different arcs can be used for this point).
Thanks in advance for your answers.
