You were the youngest child in the Todoroki family, you were only 4 Years old, You shared the same quirk, Blue flames.

When Touya wasn't a villain, You had a strong relationship with him, Which after his death, You hadn't known about that because you were small and young.

Your brother Touya, was a living flame at this point, he kept attacking his Father, but since he was trapped in Endeavors hug grip. Trying to get as far in the sky as he can so other people won't get hurt because of the explosion.

Fuyumi, Natsuo, And Rei tried using there frost Quirks to cool Touya down and his flames, but it wasn't enough because they were still getting burned.

You were in Natsuo's arms, as he tried to use his quirk at the same time while holding you, It was very difficult for him to do all of it at once.

When you turned a blue flame in your small palm, somehow it had an effect on Touya and somehow it calmed him down a little bit at the sight of your small blue flame in your small palm.
