Satsuki Kururugi (枢木皐月 Kururugi Satsuki) is one of the main characters in I-Chu. He is a part of the Idol Unit, Twinkle Bell, which was the second to be introduced in the game.

Profile Description Edit

A mischievous boy. Because of his brother complex, he’s always clinging to his older brother. He’s an honest boy and tends to wear his heart on his sleeve. He plays pranks on the producer, but she always manages to avoid them, which frustrates him. Since Akio Tobikura's reactions are the most interesting, he’s always setting up pranks on him.


  • Make a simple self introduction
    • Satsuki Kururugi. Mutsuki's younger twin. I'm gathering fans who want to get pranked by me! Ishishi!
  • How did you become an idol?
    • Obviously because I wanted to stand out! See our twins' Miracle Power and cheer on us!
  • Your impression upon meeting the other members?
    • We've a~lways been together since we were born! I don't have any memories without Mutsuki!

Personality Edit

Satsuki is an extremely energetic young boy- unlike his twin brother Mutsuki- who is very confident in his skills to pull pranks on others and takes pleasure in surprising those around him. He enjoys vivid reactions (probably why he targets Akio - who gets scared easily- a lot) and is not deterred by any complaints he gets. He has quite a carefree nature- doing as he likes and doesn't mind hitting on the producer once in awhile and pulling pranks on her (although she puts effort into avoiding both). Satsuki gets along really well with his older brother and they are almost always together, though Satsuki strives to stand out as an idol. Occasionally, he works on polishing up his sexual appeal. He is fond of playing games.

Appearance Edit

Satsuki has straight, pale beige-colored hair that sticks out at the sides. His hair goes down to the middle of his neck in the back, and the middle of his bangs reaches down just between his eyes. His hair is parted on the left. There is a pink-colored highlight in his hair towards the right side of his head. He has pale blue eyes, and he wears blue-rimmed glasses.

Notes Edit

  1. Satsuki's trademark laugh.
  2. He says it in English
  3. Doujins are usully thinner than usual manga books, which is why "thin book" is a slang name for doujins
  4. 'Battle cry'... of some sort.
  5. Piece of paper where ones wishes are written on.
  6. rice cakes wrapped in oak leaves
