Idol group 100% is making their comeback in full-force.

The seven-member group held their first solo concert in Japan, "100% 2014 Japan Cool Live," in Tokyo for a total of two performances on July 20.

100% performed their new songs "You're Pretty" and "Summer Hero" for the first time. The boys even prepared special choreography just for this solo concert.

After their performance, the K-pop group held a special event where they invited fans to woo on stage.

The rookie group is just beginning to gain mainstream success after debuting in September 2012 under Shinhwa singer Andy Lee's company, TOP Media. 100% debuted with their first single album "We, 100%."

The boys of 100%, which used to consist of members Minwoo, Rockhyun, Jonghwan, Changyong, Changbum, Hyukjin and Sanghun, have appeared in multiple popular music programs in Korea, including Music Bank, Music Core, Inkagayo and Simply K-Pop, after they debuted.

100% underwent some changes earlier this year when it was announced that the group's leader, Minwoo, and singer Sanghoo would not be returning for the group's comeback in March.

Members Rockhyun, Jonghwan, Changong, Changbum and Hyukjin returned to the K-pop scene while Minwoo reportedly enlisted in the army to fulfill Korea's mandatory military service in April. Sanghoon is currently "taking a break before he decides on his career path," according to TOP Media.

Despite the changes the group had to go through, when it comes to being idols, the members of 100% clearly have 100% of what it takes to dominate the K-pop scene.

The group released a video of a dance rehearsal session in March, gaining the attention of fans for their impeccable choreography. Their track, "Beat," was written and composed by Super Changddai, according to Allkpop.

While working with Super Changddai, it seems that the idol group has officially proven themselves to the producer.

"100% is a skilled group, rich in musical talent. Each member has their own distinctive voice. I am looking forward to seeing their debut performance," the producer had stated during an interview with Naver before the group's comeback.
