(Oh goodness this came out longer than I anticipated)
Alrighty, my ideas for Tsukiko's backstory are more like... why she dislikes failure, and why her quirk is the way it is. Alright, so first off, her parents. They are a decently-known hero duo known as the 'Comet Duo' due to their combinations of quirks. Her father, whose hero name is Sunpull, has a quirk similar to Uraraka's, but he can lower or increase gravity in an area of effect range. Her mother's quirk is to move is to move solids and liquids. She can only move them upwards like she was throwing it, meaning that it would fall back down eventually. However, when objects are falling, she can make them instantly go to their terminal velocity, being able to make large enough things fall and cause a quite a bit of damage, like and asteroid, hence her hero name, Asteroid Fall. Combining their quirks, Asteroid Fall can make them go up however far she wants and for how long she wants, then just make them fall instantly to their terminal velocity. Combining the hero duo's quirks gives you Tsukiko's quirk, but her quirk has a few extra abilities.
Now on to why she dislikes failure. Having a hero as a parent already gives a lot of pressure to do well and become a hero. Having two hero parents doesn't help at all. Tsukiko likes to impress people if she likes them, and these are her parents, of course she's going to try to impress them. She mostly really applied the pressure to herself to do good because she didn't want to disappoint her parents.
