Mo Su Kuchiki is a girl from an ordinary family. The only difference is that she came through clothing. (Really, it's just a little stronger and a little faster)
There's no power (it's true, {emphasis added}), it's just that my grades are too good to be true.
However, her parents are unusual. One is the Cursed Daughter (a child of the Uchiha and Hyuga tribes), and the other is the captain of the Gotei Thirteenth and Sixth Division (no need to guess, this person is Baicai).
It wasn't until she was 19 years old that she truly inherited her parents' power.
