16 parts Ongoing Asami has grown up. Shoto knows this, Fuyumi knows this, Natsuo knows this. None of them like it. After the bombings it was obvious to the siblings that their baby sister changed, even more so when she returned from being kidnapped by villains. Her smile had dampened. And they didn't like it.
Now older, Asami, though unsure of the hero path, knows what her goal in life is. To protect. At 13 years old Asami had an end goal, but no one ever said getting to it was going to be easy. Laughter, broken promises, hidden messages, new friends, new faces, and new villains. All getting thrown at a child.
Can she handle it? No. Not on her own.
Lucky for her, she has a best friend, two older protective brothers, an optimistic sister, and a class filled with slightly older kids willing to guide her as she walks on - even if they themselves don't know what they're doing.
Oh, let's not forget the sudden change of her half assed father who wants to not half ass being a father anymore. But changes take time, and changes bring forth secrets. Secrets none of them were prepared for.
A secret that from the shadows, promised to protect the only sunshine in his life. The only one holding his sanity and morals together. The only one making him reconsider his death. And he'll make sure he protects her this time.
By any means necessary.
Squeal to; Todoroki's little Sister.
