Kotoko Utsugi is a character in Danganronpa: Ultra Despair Girls, and her title is the Lil’ Ultimate Drama. Kotoko is a hot-headed but cheerful girl with a passion for things she considers “adorbs.” She has a habit of going off-topic and listing facts in the middle of conversations, sometimes vaguely linking back to the topic she’s talking about. Even still, she still has clear speech. Though she puts on the front of being cheerful and polite, she can be a bit of a bully and be cruel to others, such as being extremely mean towards Jotaro and teasing Nagisa mercilessly - especially about his crush on Monaca. When it comes to the Lil’ Ultimate Homeroom, she constantly tries to suck up to her and stay on Monaca’s good side. 

She seemingly loved the stage life and loved to act, but due to past trauma, she never likes to talk about it or look back on it. Because of how much she’d be pampered, she grew to become a bit strict and demanding of others. She also has a habit of curtsying and being quite a drama queen, hinting back to her time as an actress. However, because of how skilled she is at acting, it’s heavily implied that a lot of her behavior is just her putting on an act - including her “cutesy” personality is implied to be an act she’s putting on as a coping mechanism to keep acting if she doesn’t want to end up depressed. Being one of the more intelligent members, she can understand things a bit quicker than most kids her age and even uses her acting skills to deceive Monaca after she backstabbed her and the other Warriors, and can think for herself without Monaca’s influence. 

(CW: S*xual Abuse and P*dophilia) 

Because of the sexual abuse she experienced while she was acting, Kotoko can get triggered by the word “gentle” since it was a word that the men who abused her would use for her. Even though she can use the world herself without a lot of trouble, if someone else says it, she can become extremely anxious and experience a very awful breakdown, sobbing in fear and not being able to calm herself down until someone she deeply trusts intervenes. Because of this trauma, she became extremely bitter towards adults - because nobody helped or saved her, she became extremely paranoid and distrustful of adults.

For Kotoko's voice, I love the direction they took in the JPN version, having her voice be a bit higher pitched and "cutesy." However, when she speaks in a more "serious" or angry/frustrated tone, I think going in a direction similar to her ENG voice works (Also as a way to hint at her acting abilities for her to put on a voice/tone depending on how she's feeling.)
