(Oboro!Alive!Au) You were a transfer student, from a normal high school. Present Mic was your homeroom teacher, and you were all testing your quirks.

Present Mic walked up to you, as you started practicing your quirk. He hadn't read your files yet, so he had no idea what your quirk was. With your back turned to Present Mic, you used your quirk, creating a portal.

He froze, his smile dropping. Your quirk was exactly like Oboro's. "Hey, kid, your quirk...who'd you get it from?" He asked, shakily, not knowing that you were Oboro's child.
