ASP (ANAL SEX PENiS) is a Japanese idol group formed in March 2021 under WACK. They describe themselves as "ANTi STYLE IDOLS". The group currently consists of four full-time members, including former members of CARRY LOOSE and WAgg.
- Yumeka Nowkana? (Founding Member)
- Nameless (Founding Member)
- Mog Ryan (Founding Member)
- Nayu (Founding Member)
- Yuki Reysole (Temporary Member)
Due to the disbandment of CARRY LOOSE, WACK President Watanabe Junnosuke set out with the idea to create a new group due to the Coronavirus pandemic leaving CARRY LOOSE with various unfulfilled goals. As it had been 6 years since a WACK group started without any kind of label, self-releasing a group with unlimited creative freedom became the idea, or in Watanabe's words: "I wanted to be able to do whatever I wanted". The phrase "ANAL SEX PENiS" became stuck in his head, and the group's name was turned into an acronym based off of that. Various other themes were considered with the additional creative freedom too, with the phrase "ANTi SOCiETY PUNKS" being a reference to Brand-new idol Society and the idea of doing something in the vein of 1st generation BiS while simultainiously juxtaposing it, similar to BiSH and the latter generations of the group. Another core theme would be the unknown - with the members starting out with no faces to being revealed slowly over time and again with their start being without any kind of label be it indie or major. 
Yumeka Nowkana? and Uruu Ru were originally selected as members, however Uruu left the company during the group's infancy. Nayu was later selected during her temporary hiatus while healing from her leg injury, and Mog Ryan due to her growth between the 2020 AUDiTiON CAMP and the online Project WACKchin Audition. Nameless was chosen as the final member during an interview in February for the 2021 AUDiTiON CAMP. Nameless was told not to go to the camp as Watanabe felt she'd fail, but she could start a new group right away.
In December 2020, A Song of Punk was composed as a starting point for the group's musical theme. Lyrical inspiration would be taken from Japanese punk bands and musicians such as THE HIGH-LOWS, Thee Michelle Gun Elephant and Fishmans.
Reveal and Post-Debut
At the end of the WACK AUDiTiON CAMP 2021, on March 27, 2021, Watanabe Junnosuke announced the formation of a new unit, named ASP. Rather than selecting audition participants to join the group, the members had been pre-selected and appeared at the camp in-person, with their faces hidden by gimp masks. In addition, rather than stage names, each member was instead given a number identifier, from 0001 to 0004. As with several past WACK idols, ASP were to have their faces obscured until each member reached 15,000 followers on Twitter. The minimum goal was then extended to 20,000 due to how quickly the members appeared to be gaining followers. Various news articles and tweets were posted with the hashtag "#ANALSEXPENiS", which got a large reaction both from people in Japan and in other countries.
ASP's official SoundCloud was launched on March 29, along with their first song, Haikei Rockstar-sama (FAKE). The song featured Watanabe's vocals instead of the members, as is traditional with newly-launched WACK units.
On March 30, the members began reaching their goal of 20,000 followers. Rather than revealing their full face, the masks were cut to show their eyes instead. Further parts of their masks were gradually reveal parts of their face.
On April 9, the identities of the founding ASP members were revealed as Yumeka Nowkana? (0001), Nameless (0002), Mog Ryan (0003) and Nayu (0004). Yumeka Nowkana? was previously part of WACK as a member of CARRY LOOSE, while Nayu was a WAgg trainee who had been on hiatus since October 2020.
At the same time their faces were revealed, ASP announced their debut album, with two songs from the album being released on Soundcloud at the same time; BE MY FRiEND and the official recording of Haikei Rockstar-sama. Later that same day, an additional announcement was made that Yuki Reysole would temporarily join ASP at a later date.
ASP's first album, ANAL SEX PENiS, was released on May 26. Leading up to its release, songs from the album were gradually added to Soundcloud on a weekly basis.
ASP held their first oneman live at Nakano Heavysick ZERO on May 30. The event was announced just 10 days in advance. Tickets for the live were distributed via a raffle lottery at WACK's MULTiPLE MANiACS store, with other raffle prizes being a rice cooker, a travel catalogue and a gift card for some Matsusaka beef (Japanese luxury beef from the Matsusaka region). Tickets for a cinematic broadcast of the live were also given as a prize, so that once Heavysick ZERO's capacity was reached, more people could still watch.
The day of the event, they also announced their first live tour and that the eventual plan for the group was to bring back things like stage diving, moshing and lifting, which other WACK groups can no longer do. The fanbase name was also announced as Narazu-mono ( ならず者), and on June 4th, the official ASP Twitter posted that "Rogues" was the official translated name.
In late May, ASP announced an upcoming single for August 31st. This single would include Yuki Reysole as a member, and would be released concurrently with six other WACK releases also featuring her However, in early June, its release was postponed indefinitely so that Yuki could receive emergency surgery.

On August 18th, it was announced that ASP and BiS would hold a joint audition for additional members. By the end of the first deadline on August 30th, Watanabe claimed that only 10 people had applied, though some fans were unsure of the validity of that claim.
