It has been decided that the stage collaboration project, which was held up to Vol. 5, will be held at "one room party vol.7"!

This is a special event that can only be done at a fan club-exclusive live show, something that would never be possible at a regular concert.

This is your chance to perform on stage with back number!

We look forward to receiving many applications!

▼ "Challenge Room ~ one room Party Special! ~"

The team was divided into three teams: Iyori team, Kazuya team, and Hisashi 's team.

We are looking for people (6 people per performance) to take on the "challenge room" challenge in groups of three with the members!

The challenge will be a surprise until the day of the event!

▼ "Singing Collaboration"

We are looking for people who want to sing with back number! (3-6 people per performance)

Whether you're good at singing or not doesn't matter!

What I'll be singing is a surprise until the day of the performance!
