Hatsune Misawa

Hatsune Misawa (初音三沢, Misawa Hatsune ) is one of the secondary antagonists in L: Change the WorLd.

Character
Despite her harmless appearance, Misawa is quite rutheless. She appears to be rather kind and polite, but changes drastically when the situation calls for it, proving to actually be very rough. She has even been shown to be excessively brutal at times, such as when she hit a flight attendent with the butt of her shotgun, and then continued to beat him when he was down.

Plot
Misawa is first seen with her colleagues, caring to some plants. When Daisuke Matoba stabs someone, Misawa walks over to the man's dead body and aggressively steps on it, remarking that they will all inevitably die.

Later on, K and others pull up into the research labratory. Misawa exits the car and graciously apologizes to the night guard for disturbing them at such a late hour. She begins to explain herself, but stops half-way to stab him with a knife she had hidden on her person. She also kills one of the workers in the labratory, brutally slitting their throat. She was to go get Maki so that she could be used as leverage in order to convince Nikaido to not destroy the antidote, but Nikaido killed himself to prevent this from happening.

Throughout the rest of the film Misawa plays a relatively minor role, providing some brute force when needed.

She makes a more significant appearance towards the end of the movie, escorting L to K, whilst pointing a gun at him. When L tries to convince K to use the antidote to help the people on the plane, Misawa tosses her gun, pulls out a knife, and takes a baby from one of the passenger's arms. She tells L that the child and everyone else on the plane can all die, but before she can stab the child the passes out due to the virus, which had spread to everyone on the plane.

When things calm down, Misawa, along with K and others, is arrested.
