Rika

Overview
Rika is a petite girl from Nano-control that moved to Little Eden alongside her mother and brother due to her father's deployment.

Appearance
Rika is a young petite girl that is in her teens, she wears shorts and a sleeveless hoodie with the motif of a bunny. She also wears a hairband with the same motif. She has short brown hair normally held up with a headband, and she has brown eyes. She is the shortest among the main girls of the game. Her breast size is approximately A or B cup.

Pre-indoctrination
Rika is seen to be a girl that is polite and gets a long with other people, as seen by the way she talks to Lena and Kay. However, with people that she is close to, like Gwen, she holds a much more smug attitude, where she would often tease them. She also seems to be a headstrong girl, where she would barge in certain interactions she does not approve of, such as the level 2 control event between Gwen and the player and her taking things from the player by force. She is also shown to have a weakness for sleep, as she is often tired in the morning and would sleep in during weekends.

Post-indoctrination
Her personality remains largely the same, perhaps due to her willful nature. However, after becoming sufficiently corrupted, she is now more open about her feelings towards the player, and as a result would often tease the player about spending time together. Her fondness for sleeping still remains unchanged. The player can choose to break her, reducing her to a silent empty husk, only able to obey the player's commands.

Main Character/ Sean
In the beginning of the game, she is shown to treat her brother with disdain, often calling him weird or annoying. However, during the events of indoctrinating her, it is shown that she treats him that way in order to hide and deny her feelings for him, with will allow her to better get along with her friends. After becoming sufficiently indoctrinated, she becomes more open about her feelings, though she still teases him.

Elaine
From Rika's dialogue, it was implied that they share a close relationship, with Rika often calling out to Elaine whenever her brother does anything to annoy her, showing that Elaine would also be the first person that Rika runs to for help. However, their relationship seems to have taken a turn for the worst after Elaine becomes sufficiently corrupted. She would lash out at Rika for no reason, causing Rika confusion and grief. It is however possible to repair their relationship if the player manages to get them both under his control and corrupt them sufficiently. This would open up a quest to allow the player to fix their relationship.

Gwen
Rika befriended Gwen after moving to the town as she thought Gwen was "interesting" and "fun" to play with, in the literal sense. As seen from Gwen's memories, it is implied that she uses Gwen to do things for her for her convenience. However, despite her using Gwen, it is shown that she does care for her, often defending Gwen and also inviting her over to play and wanting her to stay for dinner.

Jace
Rika shows a fondness for Jace, with them exchanging looks of approval during their first meeting despite not having said a word. In subsequent meetings, they could be seen talking and Rika can be seen teasing Jace and "allow her to share the player". This fondness could be due to their similar personalities.

Kay
Rika shows a polite attitude towards Kay, volunteering to be "it" during their playtime with Sarah. However, her dialogue shows that she is distrustful of Kay, implying that her cheerful attitude is a facade.

Lena
Rika seems to have a positive relationship with Lena, whom she calls "Ms. Lena". They can often be seen playing with the cat together during the evening.

Kat
During their first meeting, Rika was shown to have a strong dislike for Kat, potentially angry and worried that there would be 1 more girl competing for the player's attention. However, she gradually warms up towards Kat, allowing her to play with her and Gwen.

Trivia

 * The original design for Rika features her with a more tomboy-ish look with no hairband, however, Aiykawa, the artist, felt that the design was a bit bland and added in a hairband.
 * The name of her teddy bear is Mr Bearington.
