Mutsuki Kururugi (枢木 睦月 Kururugi Mutsuki) 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 cool boy, opposite of his younger brother. He doesn’t try to stop anything his brother does, always watching over him instead. A boy who loves to sleep, Mutsuki does things at his own pace. He used to have a weak constitution, so he didn't have playmates aside from Satsuki. Because of that, he has a habit of drawing a line between himself and people that he interacts with. Despite that, he has grown fond of Futami.


  • Make a simple self introduction
    • I'm Mutsuki Kururugi~ I'm Satsuki's older twin. Please cheer us on~ Well then, good night~....zzz...zzz
  • How did you become an idol?
    • It's because Satsuki asked me to~ If your cute little brother says something like that to you, as an older brother, you have to stay by his side, right?
  • Your impression upon meeting the other members?
    • I have to say, thank you for being born as my brother~ Also, thank you for waking me up every morning~

Personality Edit

Mutsuki is an extremely lethargic young boy- unlike his twin brother Satsuki- and is practically always sleeping. He is an airhead with quite a carefree nature- falling asleep and taking a nap whenever and wherever he finds suitable. When he wakes up, it often takes him awhile to take in his surroundings. This nature of his often creates quite a hassle for the producer. Mutsuki is quite fond of his "cute little brother" and not only doesn't mind, but occasionally encourages Satsuki's devilish behavior. Being the older of the two, he wishes for others to see him as the mature and cool one out of the two.

Appearance Edit

Mutsuki has wavy, pale beige hair that is usually slightly ruffled. 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 right. There is a sky-blue colored highlight in his hair towards the left side of his head. He has pale blue eyes, and he wears pink-rimmed glasses.

I've had a weak body since I was little, so I didn't have any playmates besides Satsuki~

Why did you become a producer?

Actually, Satsuki and I switched glasses. They're non-prescription...

We dyed the streaks in our hair before entering school. They look good, don't they?
Mutsuki Home Reg7
Satsuki always does the laundry while I do the cooking. I'm good at making rolled eggs.
Mutsuki Home Reg8
I'm envious of Futami. Since he's a NEET, he doesn't need to work and can be lazy at home whenever he wants.
Mutsuki Home Reg10
Satsuki's pranks are adorable, so just forgive him.

Nn~ ...I'm underneath the parasol so you can come play here~ File:Mutsuki Home 3Jul2.ogg
May I stay together with you and Satsuki forever. I'll make this wish too. File:Mutsuki Home 3Jul3.ogg
