there was another child. just between Dabi and Shoto. In UA hero course. one of the six students to pass Aizawa's class. when Touya disappeared when he was 16. he was presumed dead. but she knew the real story. she was the only one who knew. she had his new number and still talked to him. they were just that inseperable. she wanted to go with Dabi, but they both knew that they wouldn't be able to fake her death because her skin was not like Dabi. she was resistant to the flames. she couldn't go. but they were planning for her to leave. They were simply waiting for their opportunity.
