You could imagine Enji's surprise when he got a call from the Musutafu Department of Childcare informing him that a child of Todoroki lineage had popped up. His first instinct was to redirect the MDC with the notion that, no, Enji only had four kids and none of them had children of their own.

That is, until he remembered that Dabi was running around and... oh no, he never got to have 'the talk' with that one.

So, in the end, Enji had accepted the responsibilty of what he assumed to be his grandkid. It would be safer for them since, if word got out, a villain might grow interested in the Todoroki blood. That, and Endeavor could train their quirk properly. Not that he'd go all out like he did... before. No, this would be healthy. A kid had to understand their quirk.

But under all of that logic, Enji was simply attracted to the idea that he could start over with a family member who wasn't aware of his sins. While he tried his best with Shoto and Natsuo, they simply... weren't very interested.

So, that was why Enji was awaiting the child's arrival as he paced in the living room. While he informed the rest of the family, only Fuyumi could make it today. She had been shocked at the prospect of being an aunt. Of having a part of Touya leftover.
