Psycho le Cému (Japanese: サイコ・ル・シェイム, Hepburn: Saiko ru Shemu) is a Japanese visual kei rock band formed in 1999. Its members are Aya, Daishi, Lida, Seek, and Yura-sama (Yuraサマ). Psycho le Cému distinguished themselves in the visual kei scene via their cosplay, with their members dressing in colorful, extravagant outfits inspired by anime and video game characters.

Psycho le Cému's cosplay inspired a dedicated niche fanbase, with fans who shared the band's interest in anime and cosplay, and some releases and events were done exclusively for members of Kronos, the band's fan club. The band creates a new set of costumes for each single. Promotional music videos often have storylines based on anime or literature. The band also performs as an alter-ego band called "Bad Boys, Be Ambitious!" Each Band member has their own personality in each character, as well as their own color scheme. Example: the Bassist “Seek” is usually the “monster” or “villain” of the story.

Psycho le Cému formed in early 1999, and released their first maxi-single “Kronos” independently in March 2000. After playing a sold-out gig at Tokyo's famed visual-kei venue Rock May Kan, the band joined strong indie label Limited Records, who released their November 2000 maxi single “Risokyu Ryokou Guide Disc”. All 15 tour shows supporting this release were sold-out, including the finale at Shibuya's On Air West.

In September 2001, Psycho le Cému released their first album, Doppelganger, and began to play nationally and in larger venues. The group was managed by visual kei specialists Sweet Heart, who have also managed Luna Sea, Shazna, La'cryma Christi, Pierrot, and Plastic Tree.

In 2003, Psycho le Cému was signed by major Japanese label Crown, and their next two singles went into the top ten of Oricon's singles chart. In mid-2004 the band made appearances at Pacific Media Expo and Project A-kon and documented the trip in the form of the Psycho le Cému in USA Live & Document DVD, which was released in September 2004. The group also kept active in Japan, among other shows they appeared later that year at a festival sponsored by Japan's visual-kei oriented magazine Fool's Mate. The group returned to the States in early 2005 and performed at three anime conventions: Katsucon in Arlington, Virginia, Megacon in Orlando, Florida, and AOD: The San Francisco Animation Convention in San Francisco, California.^[1]

On May 31, 2005, singer Daishi underwent a urinalysis that showed up positive for methamphetamine and was arrested by Kanagawa police. When the story broke in the media, all of the band's merchandise was removed from shelves in Japan. Daishi's solo tour was cancelled, and his solo EP was removed from shelves. On June 5, the band announced via their official website that they would be on hiatus due to Daishi's arrest. On September 30, Daishi was sentenced to one year and ten months probation with a suspended sentence of three years by a court in Yokohama.^[2]

The members have formed side projects in the meantime; Aya and seek are in the band ISABELLE with three other musicians, and Lida and Yura-sama are in Dacco. They have ended their relationship with their label, Crown Records, as well as with their management, Sweet Child Entertainments, and are pursuing their projects independently.^[3] Aya was in Isabelle before Psycho le Cému formed, and re-formed the group for a tour and a live DVD in 2005. Seek and Aya are currently in the group Mix Speaker's,Inc., and Seek is an active blogger.

In May 2006 Psycho le Cému toured to support the release of new album ~Epilogue ~ Kataritsugareru Monogatari. In addition, all of the merchandise that had been pulled from store shelves was reinstated, and the Live in the USA II DVD, which was delayed due to Daishi's arrest, was finally released. Although as soon as the tour was over, Psycho le Cému went on what seemed to be a permanent hiatus.

Daishi, now freed from jail, started a single career. On March 21, 2007, he released God Japanese Monster, his first solo album, accompanied of a Japanese tour.^[4] In 2009, the group announced, through their Ameblo blog, "Psycho le Cemu will be going on a short tour to celebrate 10 years since their formation. The tour will be called 「Legend of Sword」, kicks off in June." As stated, Psycho le Cému members reunited again for the anniversary of the creation of the band with a tour called 10th Anniversary - Legend of Sword, with new costumes and, the tour started in June of that year.^[5]

In 2015, Psycho le Cému reunited for three 15th anniversary concerts on February 11, 14 and 15.^[6] Later, the group announced a new single, Akiramenai Days, which was released on September 16, 2015, as well as the return of the band.

In 2017, they covered "Darlin'" by D'erlanger for the D'erlanger Tribute Album ~Stairway to Heaven~.^[7]

Musicians credits' are as per the liner notes of the group's own records. Yura-sama is always credited with vocals, although his only lead vocal spot is the song "Area" and "Janus", which he shares with Daishi, while Lida is never credited with vocals, although he raps a verse in many songs. All members may take backing vocals. Many songs have a pre-recorded or sequenced backing track, to which Aya and Yura-sama will do choreographed dance routines with hand-movements during live performances, called furitsuke (or furi for short), which in the past have often been mistakenly referred to as para para by international fans.
