■Collaboration Song "LIL BIT" MV Overview
As symbolized by the phrase "chotto chokotto," the collaboration song "LIL BIT" is a pop tune that gently affirms the feeling that it's okay not to be perfect and okay to be sweet sometimes. Take it easy and relax; it's fine to work hard sometimes and slack off at other times. Wrapped in catchy dialogue that you'll want to hum along to and the unique humor and energy of MyM, it is a perfect song for Sakuyama Choco Jiro's 10th anniversary. To fully express the 10th-anniversary theme of the "Ucho~?!" world, this MV was produced with meticulous attention to detail in its pop and colorful direction, art, and choreography. The highlights include the comical interactions and impressive performances between the three members of MyM and Choco Jiro.
Furthermore, behind-the-scenes content capturing the making of the MV and rehearsal footage is scheduled to be released on the official MyM YouTube channel. Please enjoy the behind-the-scenes production that can only be seen here.

■Interview
Q) Please tell us your thoughts on this MV shoot.
Miyuki) The appearance of Choco Jiro left a huge impression on me. Being able to sing and dance together was so much fun!
Yoshiko・Mahiru) Choco Jiro was so cute, responding with its whole body when we replied!
Q) I believe this is your first collaboration song.
Could you share your thoughts once again on collaborating with Sakuyama Choco Jiro?
Miyuki) I eat "Sakuyama Choco Jiro" often and am a big fan, so I was incredibly happy when we received this offer!
Yoshiko) It's a snack I truly love, and we got to receive "Sakuyama Choco Jiro" snacks on the day of the collaboration shoot, so I'm always very happy!
Q) Please tell us the specific points you want people to pay attention to in this song and MV.
Mahiru) We shot inside a convenience store, and we used unprecedented angles and various perspectives, including cuts from Choco Jiro's point of view. For the scene where we actually pick up the product and eat it, it was shot from the perspective inside the bag. I think all three of us have very happy expressions in those new and interesting angled scenes, so I definitely want you to pay attention to them!
Q) The theme of this song is "being yourself." How would you express "being yourself" in one word?
Yoshiko) Would it be alright if I say "sexy"? (laughs) During this MV shoot, I was told to "do some sexy movements," so I tried doing movements to seduce Choco Jiro, but Choco Jiro covered its eyes and gave me an NG (laughs).
Q) Please tell us an "Ucho~?!" (surprising) episode that happened to you recently.
Miyuki) I went to dark boxing to train my body, but I injured my left arm...
Everyone) Ucho~?!
Miyuki) I wanted to build up stamina for this collaboration song, but I ended up getting injured instead (laughs).
Q) Finally, please give a message to your fans.
Miyuki) I think the AnMs (fans) have been really looking forward to this collaboration with Sakuyama Choco Jiro, so I'm very happy that the day has finally come to deliver the MV and the song to you!
Mahiru) I'm sure AnMs will shout this when they listen to this song and watch the MV...
Everyone) Ucho~?!
Yoshiko) Please definitely watch the MV, listen to the song, and enjoy!
