Harumi questions the development of powers in Academy City, saying that the city is hiding something very important about the abilities and without knowing that, teachers are teaching it to everyone, endangering people. Mikoto doesn't believe her and attacks with magnetised iron sand, which Harumi blocks and counters with Graviton's power (with aluminium) by sending a can over and exploding it. Mikoto is able to stop the can, but a stream of other cans float around the corner. Mikoto destroys them all before they can reach her, but they were simply a diversion for a can that was sneaked behind her. The can explodes, seemingly leaving Mikoto fatally injured, buried under dust."@en . . . . .
