But it doesn't seem like they are responsible. Now really curious ... a new tailed beast? :D

Remember the Zero-Tails beast from one of the first Naruto Shippuden Movies? All the descriptions and effects of this monster possessing people completely match that of the Zero Tailed Beast. The Zero Tails basically seeks out people with negative emotions who are feeling sad or frustrated, then possesses them, causing them to go on rampages while feeding off their negative energy too. That's basically a perfect description of what's going on now. Also, Boruto asked his friends whether chakra could manifest as a monster, which was a clear reference and possible foreshadowing to a tailed beast.
