Pla2me was formed by ex-BiS member Kamiya Saki and Mizuta Mari who had previously been active as the solo "cat idol" Izukoneko. The group was announced at the end of BiS' breakup live at Yokohama Arena on July 8, 2014.
Pla2me released their first single "Plastic 2 Mercy" on September 30, 2014. There was originally a live video released for the song from their performance at Tokyo Idol Festival 2014 but, it was later removed. Maybe it was because Saki and Mari ran into the audience at Smile Garden during the middle of the song?
Their second single "UNIT" was released on January 6, 2015
Saki and Mari are good friends but, it wasn't enough to keep them together. Mari announced her intentions to leave the group on April 1, 2015 and had her final live with Pla2me on May 31st.
Shortly after Mari's last live, Pla2me changed their name to POP (read as "P-O-P"), which is short for Period of Plastic 2 Mercy and introduced their 4 new members in a way very similar to how the members of BiSH had been introduced. Although POP kept and rearranged several of the songs previously done by Pla2me to fit the new 5 person lineup, their look was very different! They would perform in sauna suits and track suits, which was pretty crazy considering that the new formation began performing just as summer was starting.
POP released their first album "P.O.P" on August 4, 2015 which included rerecorded versions of "Plastic 2 Mercy" and "UNIT" and the lead track was "pretty pretty good", which features some choreography that looks a lot like the one from the BiS classic song "nerve".
Saki was placed on indefinite hiatus after their one-man live at Daikanyama UNIT due to disciplinary reasons. Many have said it was due to something that caused them to be removed from the 2nd day of TIF 2015. Whatever the reason was, it is not shown in the video from their performance at the Sky Stage.
They released their 1st single as POP "Happy Lucky Kirakira Lucky" on December 8, 2015. This was days after Kamiya Saki returned to the group after completing a 100km marathon from Fuji-Q Highland to Shimokitazawa Shelter in less than 24 hours. She got to the venue around 9 in the morning and the live started around 11:30am. She and the rest of POP then did release events for the single from December 6th until December 13th as well as appearing at BILLIE IDLE® presents Brand-new Idle Society on December 12th with the other groups that the 6 final members of BiS are currently in.
"Happy Lucky Kirakira Lucky" brought another style change with the introduction of idoly outfits with different colors for each member.
POP's 2nd single is titled "QUEEN OF POP" and will be released on March 15, 2016.
