MHA_What the night brought

(You are part of 1-A)
Today everything was normal, the birds were singing, the sun was shining, and people were disappearing...

Entire houses devastated every night, with no survivors or bodies, only rubble. Today, after a huge investigation, nothing was achieved again, since not even the LOV would be capable of that, and if they were, why would they do it without even stealing anything of value?

Night fell, everyone was tired, exhausted from so much effort, gathered in the common room by a strange, inexplicable fear. Bakugo, Deku, and Kirishima sat together in an odd silence, Mina, Uraraka, Hagakure, Tsuyu, Jiro, and Momo huddled together in a corner filled with pillows, and the others doing their own thing.

Everything was relatively normal until... the lights and signal started to fail, something was interfering, along with distant noises, and to top it all off, there were constant, slight tremors, like giant footsteps...

Deku: A little nervous . Guys... What's that sound...
