About half an hour into the shoot, the crew began to suspect something was not right with the invisible girl: she was taller and much more voluptuous than what the records had indicated. Suspecting this might be a doppelganger, they asked Toru directly. She explained that it was all a part of her new ability of her quirk and even demonstrated live.
However, this just indeed the work of a quirk, just not Toru’s own quirk. The truth was that Toru had long been possessed by Toga, just like Uraraka. A few weeks ago, the two met at Uraraka’s just apartment and, while Toru wasn’t looking, Toga had Uraraka mixed a large amount of her own saliva into Toru’s drinking cup. Then, by allowing Toru to drink it, it led Toga’s spirit to slip into Toru’s body since she now had a part of Uraraka inside of her. After subduing Toru’s consciousness, Toga was now in control of both Toru and Uraraka, allowing her fantasy with Uraraka come true.
After the intense session, Toru had ingested even more of Uraraka’s bodily fluid, allowing Toga to have even greater control over her. Although the control was only temporary until Toru’s body fully digest the fluid she had consumed, Toga had a way to counter that. By using her weakened quirk, Toga morphed parts of Toru interior into Uraraka’s, thus allowing her to stay in Toru’s body indefinitely. By concentrating the transformation on just the chest area, Toga could then add Uraraka’s and her own bust onto Toru, making her own busts much, much larger. And what’ more was the fact that this allowed Toru to use weaker versions of both Toga and Uraraka’s quirks, turning her into a holder of three different quirks.
Back to the present, Toga (as Toru) agreed to do a few “risky shoots” to get the crew off her back. Although she did not really care about what the crew thought of her, she did need the huge sum of money from the shoot for her future schemes…
