"Osana's good friend, Erika will most likely confine her secrets to her"

"Her younger brother will be attending Akademi next year"


Erika wears the default school uniform unless customized and wears light pink panties underneath. She has light brown eyes, and light salmon colored hair that reaches her shoulders, tied very loosely into a braid hanging off her left shoulder held by a small red bow. She wears a light blue kerchief and matching apron with pictures of small bunnies printed on it. When listening to music in the halls or before class, she wears black headphones with little silver cat ears. She wears short pink stockings, has a silver bracelet with a flower charm clipped to it.

Outside of school, she wears cute, causal clothing. Her favorite is a blue tank top with a light pink knee heighten skirt. As pajamas, she wears lavender tank top with matching pajama pants with pink cats.

Every Monday she wears a normal loose braid, every day after that she changes her hair, on Tuesdays she wears her hair down with a large blue bow on the back, on Wednesdays she wears two low ponytails with red bows, on Thursdays she wears her hair down but with a blue hairband with a small pink bow, and on Fridays she wears a ponytail held with a large red bow.


Erika is a sweet and slightly light-headed second year student. Despite being a loner, she will still strike a cute pose when a camera is aim towards her, if she sees a corpse, she'll switch to the Lovestruck persona, she will run to Uekiya, run out of school with her and call the police. If she witness Ayano murdering Osana or Uekiya, she'll switch to the Hero persona and attack her with more strength then what she's capable of.

When not liking peace and solitude, she finds joy in cooking cute snacks for her fellow students and watching them enjoy what she made. Being stuck in the closet, Erika is afraid of coming out to her classmates, unsure of their reactions. However when it comes to Uekiya, while she is shy and nervous around her, she can be a bit stalkerish and obsessive towards her, despite this she's not a Yandere as she hates the idea of harming other people for a love interest. She cares a lot about her friends especially her good friend Osana and her fellow Cooking Club members, and will try anything to protect them from harm. She's on neutral terms with other students, but still acts friendly to them if they mean no harm to her.


Erika's mother was born an American in New York City named Sarah in 1990s, Erika's father named Haru was born Japanese, he vacationed to America to visit a relative in his teen years for Christmas. He and Sarah meet at a movie theater to see the rerelease of Home Alone when they sat next to each other, after the movie, Sarah began chatting with Haru, getting to know him better. After Christmas, she was heartbroken to learn that Haru has to go back to Japan, but he promises to call her. Upon finishing high school, Sarah saved up most of her money to fly to Japan, upon getting enough, she flew there and meet Haru face to face. In the late 1990s, they finally married and had a son in 1999, three years later in 2002, they had a daughter, Erika.

Erika was born into a small family. Her older brother graduated from Akademi, leaving her as the eldest to her two younger brothers and sister who are currently either in Elementary or Middle school. Her first younger brother will be attending Akademi next year. Growing up, Erika had a normal life, though her parents and siblings knows well that she's lesbian and has a crush on the Gardening Club leader, Uekiya, they also know Erika has trouble telling her friends about her sexuality. They support her and hopes one day she'll come out.


7:00am-7:05am: Enters school grounds, and changes her shoes at her locker

7:05am-7:15am: Briefly chat with Uekiya.

7:15am-8:00am: Goes to the Cooking Club, cook some cute sweets and walks around school grounds, offering them to various students. Her favorite spot to share sweets is the rooftop.

8:00am: Goes to her classroom, and sits at her desk. At this time she's texting or listening to music on her phone.

8:30am: Starts her morning classes.

1:00pm: Goes to the rooftop to eat lunch before secretly following Uekiya to the Gardening Club, and admiring her briefly.

1:30pm: Goes back to her classroom and starts her afternoon classes.

3:30pm-4:00pm: Participates in Cleaning Time, cleans out the chalk erasers and mop the floors.

4:00pm: Walks to the Cooking Club and participates in the club activity till the end of the day.

On Thursdays, during lunch, she eats lunch first before going to the shower room to change into her bathing suit, she goes to the pool area and join Osana along with the Bullies to sunbathe for the rest of the period, there she chats with Osana. One Thursday, during Kizana's week, after sunbathing and changing into their normal clothes, Erika will talk to Osana about her sexuality and feelings for Uekiya near the showers. If Uekiya is missing or murdered, Erika will spend most of her free time mourning near the Gardening Club.


Her Family

Erika loves and adores her family more than anything. She's usually alone with her siblings as their parents usually not being around due to work, leaving them with less time to bond. Erika is pretty protective and doting to her younger siblings, and looks up and greatly admires her older brother, still keeping contact with him through phone calls and texting ever since he moved after graduation.

Aran Mori

Her older brother. Aran moved to New York City after graduating from Akademi. Erika greatly admires him and greatly misses him, due to just moving from home, it was difficult for him to return home till the time being.

Noa Mori

Noa is Erika's younger brother by two years. Like Hiro and Risa, Erika greatly dotes, and spends as much of her time with him. Noa looks up to his sister, though he finds her overprotective and doting nature slightly over the top, he appreciates how much she cares about them when their parents are absent.

Hiro Mori

Erika's younger brother by three years. Hiro is very timid, and shy, which Erika tries to handle by trying to make him more confident in himself. Though Hiro doubts she'll help him, he accepts how she at least tries.

Risa Mori

Erika's only sister by five years, Erika greatly loves her and is the most protective of her.

Uekiya Engeika

Erika has strong feelings for her, and is very reluctant to admit her feelings as she doesn't know if Ueyika likes girls. They first meet when Erika was admiring some of the flowers she planted in the garden, after a brief talking they become good friends, but as time went on, Erika saw Uekiya more than a friend but was too shy to confess her feelings. Erika sometimes talk to her in the morning, but never dare to ask if she likes girls, in her freetime, Erika likes to admire and stalk Uekiya. She really cares about her safety and wants to make sure she's safe from any form of danger, if Erika witness a murder, she will convince Uekiya to leave school with her and call the police. If Uekiya goes missing or is killed, Erika will fall into a deep depression.

Osana Najimi

Osana and Erika are good friends, though they see each other a few times a day, they have full conversations every Thursday while sunbathing. Like her parents and siblings, Osana is one of the very few people that is aware of Erika's sexuality and keeps it secret. Sometimes on weekends, Osana and Erika often text each other and hang out outside of school. It's very unlikely for Erika to fall in love with Osana if Uekiya doesn't return her feelings, as Erika just sees Osana as a friend, and vice versa. If Erika was to be hurt, Osana will sometimes comfort her but will mostly keep her distance. If Osana was ever missing or murdered, she would be very sad.


"Well, now that you mention it, yes I'm in need of your assistance. Just don't tell anyone! D-do you know the Gardening Club leader? I wanna... I wanna give her a secret admirer gift but I don't want her to be suspicious when she sees me all nervous and shaking giving her the gift.

(Osana: "You've been acting pretty weirdo around a few girls lately. What's going on?)

"Well... Just don't tell anyone about this, okay?"

(Osana: "Don't worry, you can trust me.")

"Yes, I'm... I'm gonna admit it.. I'm a lesbian.. I didn't chose to be one, though, I know I was. Throughout my younger years, I always felt.. Attracted to girls. In school, when girls only talk about boys, boy bands, and boy celebrities, I thought of girls, girl bands and girl celebrities. It took me so long then I figure out I was gay..."

(Osana: "Whoa.. How did your parents react?!")

"My parents were supportive of it. They were surprised but knew they couldn't change my mind about it. I even developed a crush on... on.."

(Osana: "Spit it out! Who?")

"Okay, okay! I'm in love with... The Gardening Club leader, Uekiya."

(Osana: "Whoa, her? But I guess that's fine, I mean I was in love with Taeko, my childhood friend but I decided to stop, I still care for her, plus I know she's bisexual long before I discover my own sexuality, I'm sure. But how will you know if Uekiya's a lesbian or even bi or pan?")

"Please! Just don't anyone about this. Okay?"

(Osana: "I won't okay? Sorry if I made you uncomfortable mentioning my former crush. I promise I won't blab this out to anyone.")

"Thanks, Osana. You're a true friend."

(Osana: "Don't get sappy, please. Now we better change up and get to class fast.")

"Oh. Of course!" -Erika's conversation with Osana in the girls' shower room on Thursday during lunch.


Erika wants to give Uekiya an anonymous care package containing a secret admirer letter and a whole butterscotch-cinnamon pie she've baked along with Uekiya's favorite flowers, but is too nervous to do it herself. During Cleaning Time or before and after class, Ayano must give the package to Uekiya and ask her opinion on it then report to Erika the results.
