The 765PRO Live Theater opens in two months, so Mirai proposes holding a concert in the field next to the building, and her idea spreads among the other members of the MILLION STARS.

But it'll be difficult for 
everyone to participate.
لكن سيكون من الصعب

Pero será complicado
que participéis todas.

de toutes vous avoir.
