Ryusei Koki was one of the male students that attended Akademi High School.


Ryusei wore the default male school uniform, unless customized by the player.

He had spiky cobalt blue colored hair swept up and back to the right, with two strands protruding to the right on his face. His eyes were dark cobalt blue.

As of the September 1st, 2017 Build, he wore blue framed glasses.

Among the types of personas included in the game, he was a Teacher's Pet. If Ryusei saw a corpse or witnessed a murder, he would report to his teacher, unless another Teacher's Pet already has. He would give Ayano a suspicious look before crossing his arms if she aimed her phone at him. He could not participate in physical fights.


At 7:05 AM, Ryusei entered the school grounds. He walked to his locker at 7:10 AM and changed from his outdoor shoes to his indoor shoes. At 7:15 AM, he walked into the plaza, to the right side of the fountain, and gossiped with Haruto Yuto, Sota Yuki, Hayato Haruki, Sora Sosuke, and Riku Soma.

At 8:00 AM, Ryusei walked into Classroom 2-2 and sat at his desk. He started his morning classes at 8:30 AM, and left to go to the cafeteria to gossip at 1:00 PM.

Ryusei walked back to class again at 1:30 PM and participated in cleaning time between 3:30 PM and 4:00 PM. He then headed to his locker and changed from his indoor shoes to his outdoor shoes, then he lingered there until 3:50 PM, when he walked home.


  • His name was a reference to the most popular male Japanese names for 2012, 7th most popular being Ryusei, 8th most popular being Koki.[1][2]
  • Name 竜聖 Ryusei means ”Holy Dragon” (竜 Ryu means ”Dragon”, and 聖 Sei means ”Holy”). Surname 幸輝 Kōki means ”Fortune Shine” (幸 Kō means ”Fortune”, and 輝 Ki means ”Shine”).
  • His female counterpart was Mei Mio.
  • His hair was modeled after Lloyd Irving's from Tales of Symphonia.[3]
  • Before the June 29th, 2016 Build, Ryusei arrived on school grounds 11th in line on the left side, at 7:05 AM.
  • Ryusei was the only student in his group to not change persona in the September 1st, 2017 Build.
  • As of the August 18th, 2018 Build, Ryusei has been removed from the game. YandereDev said that he (with the other rainbow students) will be put back into the game once the frame rate is stable, and if not, then he (along with the other removed rainbow students) will appear in 1980s Mode.
  • If he and Mei were in a club, they'd be in the Science Club.
