- Intercourse with You: Pretty much all their songs, besides Miracle Twinkle.
- Silly Love Songs: Likes this trope even more than F∞F.
- Techno: Mixed with Pop.
- Trickster Twins: If I-Chu was more popular, these two might as well become the poster boys at this point.
- Mutsuki is downplayed somewhat compared to Satsuki, as he's more likely to be asleep.

Mutsuki's younger twin. He is a bit attached to his brother. He's surprisingly honest and forward with his feelings, so he can be really blunt or rude sometimes. He tries to play the pranks on the producer, but it's rare she actually falls for them. He became an idol to find fans that'd love to be pranked by him.
Tropes:
- Cute Little Fangs: Has a very prominent one.
- Defeat Means Respect: After the Producer beats him at dancing to prove that she's capable of teaching them, he starts sticking to teasing her as pranks instead of being an outright dick.
- Fish Outof Temporal Water: In his Ikemen Sengoku event story. He time traveled back to the past and met Date Masamune.
- Eyepatch of Power: Seen in his Ikemen Sengoku LEs. Subverted, they're purely cosmetic.
- Hidden Depths: Without Mutsuki, he feels like he can't accomplish his dreams.
- Jerkass: He regularly picks on Akio without any sort of remorse.
- Jerk with a Heart of Gold: Then he told ArS about Akio's worries, and helped the poor guy out.
- He really cares about his own brother.

Satsuki's older twin. He has always had a poor constitution, so he used to have only Satsuki to play with back in his childhood. Up to this day, he regularly takes naps. He only became an idol because Satsuki wanted to. Although he appears constantly sleepy, he's just as mischievous as Satsuki sometimes. He doesn't stop his brother from playing pranks, because he thinks Satsuki's pranks are cute.
