They are not two different semblances but linked (Now realizing that.) When she releases final burst, momentarily she can use Sirens Scream immediately considering her large storage of energy capacity she has along with the other teachers.

Dude, you didn't answer my question. She seems to have two distinct and completely unrelated abilities. One is a variety of different functions revolving around the manipulations of sound waves. The other is the ability to heal allies within a certain area around her. Every character is allowed one semblance, depending on the nature of that semblance it could have a variety of functions. Like Sapphire's ability to remain unseen by anyone could at some point grow into the ability for her to manipulate how people see her. In that area your character seems to have a problem. She has all of these powers directly related to sound wave manipulations which is perfectly fine but she also has the ability to heal allies in a set radius around her and there is no apparent link between the two of them. Your response to my question was less than informative, would you care to try again?
