What are dreams? Busy second-year middle school student Kasuga Mirai still doesn't know what her dream is. When she happens to receive a ticket to a 765PRO ALLSTARS concert, Mirai meets fellow second-year middle school student Mogami Shizuka, who has dreamed of becoming an idol since she was a young girl. Also in the audience is Ibuki Tsubasa. While all three of them watch, the curtains rise on the stage!

Mirai and Shizuka practice hard for the 765 Production audition. The auditions for the new project have been going smoothly, and Tsubasa decides to become an idol. 35 girls have already passed the auditions and begun their lessons. The day of the final audition arrives. After the interview, Mirai and Shizuka move on to the stage audition, but...

Mirai, Shizuka, and Tsubasa have joined the MILLION STARS, but the 765PRO Live Theater that will serve as their home base is still under construction. While walking with the producer assigned to the project, the members of MILLION STARS show up one after another. Overwhelmed by their personalities, the girls immediately jump into their dance lessons. Even the touring members of the 765PRO ALL STARS learn the MILLION STARS have finally begun operating.

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. As their dreams expand to include food stalls and attractions, doubts about performing in an incomplete state grow as well, and the producer who had been merely swept along until now finally opens his mouth.

With the field concert approaching, the MILLIONSTARS are with lessons and preparations. Their biggest task is creating the tent that will serve as their stage. The producer brings sleeping bags to the members who are up late working. Once they're wrapped up in their sleeping bags, Mirai thanks the group. Finally, the day of the concert arrives.

The pre-opening event is a huge success, but Shizuka's concerns are also revealed as the event ends. Her father will only allow her to work as an idol while she's in middle school, but the producer understands Shizuka's desire to continue being an idol. Finally, the producer announces a press conference will be held for the MILLIONSTARS' debut.

Everyone is talking about MILLIONSTARS Team1st's debut concert, and Team2nd and Team3rd are set to appear on a special travel episode of "Is This Live?! Sunday". The two teams race through a seaside obstacle course for the right to perform their debut concert at the end of the show. The ten members overcome various obstacles as they head towards the finish line. Which team will win...?!

Team4th and Team5th are debuting on the same day. When Team4th arrives at the amusement park where they will be performing, they discover their stage has been flooded by broken water pipes. In its place they're provided with a run-down stage, and only a handful of people come to watch their first performance. Meanwhile, Team5th runs into trouble with their own performance. Can both teams overcome the crises they're facing?!

Team6th makes their debut on a music program, and Team7th will debut at an artist-focused festival as the only idol group. Only Mirai, Shizuka, Tsubasa, Kaori, and Tsumugi of Team8th remain. Before their debut, Team8th are instructed to perform as backup dancers for the 765PRO ALLSTARS. Team8th are overwhelmed by seeing the ALLSTARS up close.

Shizuka is asked to perform at Chihaya's charity concert at the last minute. Mirai suggests this might be an opportunity for Shizuka's father, who opposes her becoming an idol, to see her perform. Through her lessons with Chihaya, Shizuka feels strongly that she wants to become more like Chihaya so her father will accept her dream. Two days before the concert, Chihaya takes Shizuka and her friends to the auditorium where the concert will be held.

The theater's opening performance is one month away. However, the 39 girls struggle to find time to meet, leading Mirai to unfurl the tent from the handmade concert and explain how they struggled to meet then too, but looking at this made her feel like they were working together. Meanwhile, the producer suggests a training camp.

The day of the 765PRO Live Theater's opening show "RAISE THE DREAM!!!" has arrived, marking the beginning of the MILLIONSTARS' future on a new stage!
