In one song, the heroine wears slightly revealing dresses but nothing is explicit.

A lot of intense fight sequences; people are stabbed with strong weapons, hit with a baseball bat, and get crunchy punches and strong blows delivered to their bodies.

Blood is occasionally shown during the fight sequences whenever the characters are struck with deadly weapons and blows.

The climax fight is bloody and violent.

Characters abuse very infrequently and mildly.

A character puts a cigarette in his mouth, but doesn't smoke it.

In some scenes, buildings and other places are shown burning.

In the mortuary, we can see the burned bodies. While the woman sees the burned body, she mourns. This could be upsetting to the viewers.

The climax fight is violent and powerful.
