Mahiru is an optimistic and sensible girl who is generally rather calm and unafraid to speak her mind. She initially comes off as confident but is later revealed to have self-esteem issues; believing her title to be stupid when compared to her classmates. Mahiru has high expectations of men and can be abrasive towards them, yet she is much more tolerant and friendly to girls. While she doesn't flat-out hate men (like a character from a different Danganronpa game), she is much less patient towards men and is quick to judge them. As a result, she and Fuyuhiko are constantly butting heads. But despite this, she is a very kind and earnest person, wanting to help as many people as she can.

Her official English voice actress is Carrie Keranen.

I'm not looking for anything specific here. As long are you're female (or can sound female), then feel free to audition.
