2007–2012: Formation, member flexibility era

In December 2007, producer Maiko Fukushima opened the live house/bar "DearStage " in the basement of a building near the Suehirocho Station,[2] and moved it to the DEMPA Building (DEMPAビル, DEMPABiru) in September 2008.[3][4] In December 2008,[5][6] DearStage salespeople Mirin Furukawa and Akari Owada formed the original Denpagumi (でんぱ組, Denpagumi)[4][7] and released the single "Mirror Magic?" through an indie label.[8][9] Fukushima said of the unit's name: "I wanted to give it a retrotic name like Ushiroyubi Sasaregumi."[10] Also, Kenzō Saeki and Masaya Koike , who participated in the naming conference at the time, said that the part of "Dempa" was taken from the Dempa Building.[11]
In June 2009,[12] Meme Nishimura (now Risa Aizawa) and Nemu Yumemi joined.[citation needed]
Taking this opportunity, Fukushima considered changing Dempagumi's name to "renew it to a new feeling".[10] Saeki proposed "Chapé's Fountain"[10] [13] but Fukushima wanted to keep the Dempagumi name and said "If it has an extension (a la MOSAIC.WAV, LOVE.EXE, etc.), it may be good for Akiba[hara]." According to Saeki, it is absolutely necessary to avoid unit names ending in "gumi", as it would be too similar to the aforementioned Ushiroyubi Sasaregumi.
There are various accounts about the reason ".inc" was selected.[10] The meaning of "Dempagumi's evolutionary system" was once considered.[14][15] Another reason is that "it would be interesting if "inc" was added to the end of a company [name]".[11] So it was decided that ".inc" would be added, changing the group's name to "Dempagumi.inc".[10]
In addition, according to Yumemi, "The interpretation that Aizawa and Yumemi joined 'Dempagumi' and renamed it Dempagumi.inc is a little different." It is also said that it was four people of Furukawa, Owada, Aizawa, and Yumemu who happened to have passed, and it is said that it was something which was collected regardless of the original "Dempagumi".[13] Although the original name is "でんぱ組.inc", the debut single released by Lantis mistakenly named them as "でんぱ組inc."[16]
On February 24, 2010, their debut single "Kiss + Kiss de Owaranai " with ULTRA-PRISM , which featured the music of the PC game "Tropical KISS", was released from Lantis.[17][18][8][19][a] Eitaso and Miu Atobe joined on June 3,[18] and Owada graduated on July 8.[22] On August 15, Meme Nishimura was renamed Risa Aizawa,[23] and on January 28, 2011, Eitaso was renamed Eimi Naruse.[citation needed] On July 6, the second single "Piko Piku Pikatte Koishite yo ", Denpagumi.inc's first single release, was released from Lantis,[17][24] and Aizawa became the group leader at the same time.[23]
On September 9, they were transferred to MEME TOKYO, a label newly co-founded by Fukushima and Toy's Factory.[25][26] Their third single Future Diver was released on November 16, and their first album, Nē Kīte? Uchuu wo Sukū no wa, Kitto Osushi... de wa Naku, Dempagumi.inc! , was released on December 14 by MEME TOKYO.

Reception
Nikkei Entertainment described Dempagumi.inc and Babymetal as the two breakout idol groups of 2014, and perceived the fandoms' connection thorough music and concept as a common point between the two groups.
