Poison

Synopsis
After some students taste Ava and Danielle's special potion, some of the bullies fall to Ayano's antics.

Plot
Walking towards the lockers from the courtyard, Ava and Danielle almost crash in to Taro and his crew coming from down the corridor. Ava warns them not to drink any of the water in the courtyard. Danielle asks Ava why she warned them, and Ava responds saying that she isn't down to kill a bunch of kids.

Elsewhere, Toga and Hazu arrive to Kyuji and Otohiko with the same bucket of water that Ava and Danielle poisoned. They start to drink it.

Meanwhile, Osana, Taro and Hanako stand by a water fountain, while Raibaru drinks from it. A little down the hall, Toga falls out through a door, grasping at his throat, choking, gaining the four's attention. They all turn in shock and scream as they spot a room full of students, all dead, and the bucket of water splashed on the floor. They run past the room in the direction of the clubs.

On the roof, Uekiya hides in a corner with the only remaining Gardening Club members, Sumire and Tsubaki. All of them are very worried but are confident that they have escaped Nemesis. Unbeknownst to them, Nemesis stands behind a door, listening to everything they say. Suddenly, knife in hand, Nemesis walks out through the door, causing the club to scream in fear. Sumire walks backwards but goes one step too far. She trips on the railing then falls backwards on to the ground. Nemesis stabs Tsubaki in the head, then turns to Uekiya. Suddenly, Kuroko and Aoi appear nearby, instructing Nemesis to stop. Aoi calls for Uekiya, to save her. But Nemesis stabs her in the back before she reaches the council.

At the front of the school, the bullies (minus Musume, since she's dead) try to escape. Hoshiko tries to open the small gate, but it's locked. Hana tries to open the big gate by using the button, but it doesn't work. Kokoro and Kashiko try to use their phones to get reception, to no avail. From behind a bush, Ayano peers at them, watching. The bullies ponder what to do, with the Ancient Evil at the fountain, watching. Ayano is now shown to be covered in blood, clutching a screwdriver in her left hand, while stepping out from behind the bunch. She throws the screwdriver and it lands straight in the back of Kokoro's head, causing her to fall forwards and die. The rest of the bullies scream, running back inside of the school, while Ayano makes chase.
