There are two parts to this character that use dynamics. The ropes for the hair and the sweater, respectively. There is another prop that appears, a piece of paper, which also requires dynamics.
Initially I tried using bones and an Ik controller for dynamic effects.

Since the front hair is not separated and the back hair is a complete piece, the effect is not very good.
Then I used ncloth directly to use the hair as cloth.

The effect is as follows.

The same approach is applied to props.


Same for other props.
