FRUITS ZIPPER's Karen Matsumoto and CUTIE STREET's Haruka Sakuraba's unit PiKi is born
A new unit, PiKi, by FRUITS ZIPPER's Karen Matsumoto and CUTIE STREET's Haruka Sakuraba, has been formed. Their debut song, "Kawaii Kaiwai," has been chosen as the ending theme for Season 2 of the TV anime "My Dress-Up Darling," which will air on TOKYO MX and other channels starting July 5.

The announcement took place at the large-scale fashion event "OKINAWA COLLECTION 2025," held on June 21 at Okinawa Arena in Okinawa Prefecture. During the "LARME Stage" within the event, the unit's formation was announced, and their debut song "Kawaii Kaiwai" was performed for the first time. After their performance, the two greeted the audience again, saying, "We are PiKi, the unit of FRUITS ZIPPER's Karen Matsumoto and CUTIE STREET's Haruka Sakuraba!" They added with a smile, "Please support PiKi from now on!"
The choreography for the debut song "Kawaii Kaiwai" was handled by SAKO MAKITA, who also choreographed FRUITS ZIPPER's "Watashi no Ichiban Kawaii Tokoro" and CUTIE STREET's "Kawaii Dake Ja Dame Desu ka?" The song has already been pre-released on TikTok, and it is set to be released on various streaming sites on July 4. Those who pre-save or pre-add the song on Apple Music or Spotify will receive a smartphone wallpaper as a gift.

I love the fluffy atmosphere when I'm with Paru-tan, and I think everyone will absolutely love it too, so the two of us will deliver lots of cuteness ♡
During FRUITS ZIPPER activities, everyone is there for me, but for PiKi, since the other members aren't here, Paru-tan and I will do our best to send out various kinds of cuteness as a duo!
The noteworthy point of the song is that the chorus is very catchy, so I want everyone to learn it and dance a lot, and I want everyone to join in on "Kawaii Kaiwai"!
Haruka Sakuraba (CUTIE STREET) comment

I will be making my unit debut as PiKi with Karen-chan!
I'm both excited and nervous, but I will do my very best.
Our debut song "Kawaii Kaiwai" has a very cute catchy melody and choreography, so I would be happy if you sing and dance along with us and love it a lot.
I will give my all to both my activities as PiKi and my activities with CUTIE STREET. Thank you for your support!
