Ritsuko Chikanari is the fifth rival and one of the female students who attended Akademi in 1980s Mode. Following the game's storyline, she was Ryoba's sixth rival.Ritsuko has extremely pale skin and fluffy, shoulder-length layered dark blue hair with straight bangs and curly sideburns. She has red eyes and wears red nail polish. Her pale skin is a result of her genetics. She wears the default 1980s uniform with black tights and a large white bow on a white headband, which has a small heart in the middle of the bow.Among the Personas that are currently implemented in the game, Ritsuko is Lovestruck. If she witnesses a murder, she will run to Jokichi Yudasei and inform him that Ryoba Aishi is a murderer, causing an automatic Game Over. If she encounters a corpse, she will run to Jokichi and tell him there's a murderer on campus; they will then run out of school and call the Police. She is incapable of fighting back against murderers. Ritsuko will become a Loner on subsequent weeks if she is eliminated peacefully and still attends Akademi. She is very demanding and does whatever she wants. If the Pool Sign is set up, she will ignore it and comment on how she can't understand why people would listen to the sign. Her black tights represent her percieved moral alignment, which YandereDev states is the "worst" of the ten rivals. Her worldview which causes her to not care if a poor person suffers a tragedy or even dies is cited as an example.[3] Ritsuko comes from the Chikanari Family, a well known family known for their construction company, Chikanari Heavy Industries. Her father, Kiyoshi, spoiled her to the point of Ritsuko sharing a resemblance of a "caricature of an entitled rich brat."[4] According to the Akademi Daily during her Week, she is shown to have failed her entrance exams. This resulted in her father bribing the headmaster of Akademi to let his daughter enroll.Ritsuko is a snobby rich girl from one of Japan's wealthiest families. Her father is the founder and CEO of Chikanari Heavy Industries, which is known for supplying Saikou Corp with many of the materials needed for their electronic products. It's an 'open secret' that she has absolutely no intention whatsoever of getting a proper education at Akademi, and is only attending the school in order to attain the prestigious title of being an Akademi graduate. She spends her days sunbathing at the school pool instead of studying. Her 'I don't care what anyone thinks' attitude has earned her a degree of respect from her peers, and a small number of girls are now beginning to act exactly like her, sunbathing at the pool alongside her. If someone called Ritsuko poor, she would stare at the person with her mouth slightly agape for a few moments, then burst into uncontrollable laughter for a few minutes.
