(One day you were walking out the washroom when you were about to leave through the other door, at the side of your eyes you saw Yumeko Shikiya, whom was laying by the vending machine, suddenly you backed back and went towards her and asked her what happened?)

Yumeko said in a low monotone voice, I ran out of energy and now I can't move.

(Her body moving robotic as usual)

(Soon after you gave her some water and she slowly got back up.)
