If you come to understand each other, bit by bit… You’ll become the best team.
We were like that too.

Ryunosuke Tsunashi

TRIGGER’s “Wild and Sexy” is exactly that: without even trying, Ryuu’s charm speaks for itself. He’s constantly being approached by women, but…

Ryunosuke Tsunashi (十 龍之介, Tsunashi Ryunosuke), is actually a very shy and timid soul, who has a difficult time talking with women due to growing up with his brothers. There’s also a good argument for Ryuu’s naivete, if his comments to the woman at his father’s hotel are any indication.

He’s very kind and understanding to those younger than him, acting like an older brother to just about everyone. Ryuunosuke doesn’t seem to really believe in his natural erotic charm–he’s just a boy from the country, after all–and he’s constantly trying to tell people that he’s not as sexy as all those ads make him seem to please them.

Holiday / Days off

  • On my days off, I first take care of the house chores that I let pile up! I also go drink with Gaku, or invite him and Tenn over for a meal. Also, I guess I often call my family back in Okinawa, listen to my little brothers talk about what happened to them recently, or relax by making small talk with them. Things like that.

24:00 - 6:00 Sleep

6:00 - 7:00 Jogging and shower

  • Back in Okinawa too, I would wake up early and run alongside the beach! Jogging for around 30 minutes and then taking a light shower is part of my daily routine.

7:00 - 8:00 Breakfast

  • I like cooking, so when I have time, I’ll cook my own food in the morning too. That day, I made an Okinawan stir-fry with the bitter melon that my family sent me from back home.

8:00 - 8:30 Transportation

8:30 - 12:00 Magazine shoot

  • I got interviewed and got my picture taken for a gravure that will be published in a magazine. They’ll be revealing a lot, so I wonder how the fans will react (lol).

12:00 - 13:00 Lunch

13:00 - 13:30 Transportation

13:30 - 18:30 Variety show recording

  • We were able to appear on a variety show to promote our album. I never thought that I’d be the victim of a hidden camera prank! I didn’t notice at all……

18:30 - 19:00 Transportation

19:00 - 21:00 Lesson

  • Fine-tuning because we were going to appear on a music program the next day. We weren’t sure if Gaku would be able to join us since his shoot was dragging over, but the three of us were able to gather, so I was relieved.

21:00 - 22:30 Dinner

  • After the lesson, the three of us went to have a light dinner. We had to wake up early the next day again, so we weren’t able to stay for a long time, but Tenn joined us for once, so I was happy!

22:30 - 23:00 Transportation

23:00 - 24:00 Bath

Takuya Satou Comments About Part 2

Regarding Part 2

These are comments regarding Part 3 [4]


  • Thank you very much for always enjoying Idolish Seven, and continuing to support it. Thanks to that, we've been proceeding along with the recordings for Part 3, but regarding Part 3 itself, all I'd like to say ahead of time is, it's a tough one!


  • I don't think there's any such thing as a wall you can't overcome, so I want to tell him, "Let's combine our strengths as TRIGGER, and jump over that wall!".


  • Ryuu wears mostly denim for a casual aura. [5]
  • When asked who in IDOLiSH7 he thought would be older brother material, Ryuu answered with Mitsuki.[6]
  • Ryuu gets real troublesome when he’s drunk. Gaku mentions that he’ll start drawing on his stomach and dancing (hara odori).[7]
  • Once, he had to pose with a serious face while holding an eggplant for the front cover of a magazine with TRIGGER. And while checking the pictures they had taken, Gaku was laughing and Tenn was unable to stop being amused.[8]
  • Ryuu disappointed Nagi by not knowing that that day was Yamato’s birthday beforehand, so Nagi wrote the birthdays of every IDOLiSH7 member on Ryuu’s palm so that he wouldn’t forget.[9]
