A series of videos documenting her efforts to lose weight were posted to the official BiS challenge over the coming months.

On September 13th, Watanabe Junnosuke announced that Pour Lui had been suspended from BiS for failing to lose enough weight, prompting outrage from fans and media outlets.

2020[edit | edit source]

After BILLIE IDLE®︎'s disbandment, Pour Lui decided to continue her idol career. As she had reached her 10th anniversary as an idol in late 2019, she decided to commemorate this milestone by releasing a sequel to her debut album.

On January 3rd, Pour Lui made a surprise appearance at WACK's Koshien event to announce the album, Minna no Pour Lui II, which would be an official WACK release (suggesting that she had unofficially rejoined WACK temporarily). Upon the album's announcement, Pour Lui revealed that there would be further announcements to come soon.

Just three days later, on January 6th, Pour Lui made two major announcements: The first was that she had founded her own company with the help of Watanabe, PourPourLand. The second announcement was that, under PourPourLand, Pour Lui would form a new idol group, temporarily named Idol Kenkyuujo, of which she would be both a member and a producer.

On February 14th, Pour Lui appeared as a featured vocalist on the sleepyhead track, "Boku no Janai wa Kimi no Mono".

Pour Lui's second solo album, Minna no Pour Lui II, was released on March 11th.

In early April, Pour Lui revealed on twitter that the members of her new idol group would be living with her during their pre-debut era. This raised concerns as it coincided with Japan's enforced lockdown period to prevent the spread of the coronavirus. Nonetheless, Pour Lui continued to share stories and (censored) photos of the members as they remained quarantined in her apartment.

The starting line-up and name of Pour Lui's group, PIGGS, was announced on April 19th, 2020. The same day, Pour Lui's secondary BYS channel was changed into the official PIGGS YouTube, and their first song, "KICKS" was posted.

Pour Lui's first album as a member of PIGGS, HALLO PIGGS, was released on July 1st.

Personal Life[edit | edit source]

Pour Lui was born and raised in Saitama. She has one brother, who occasionally appears in her YouTube videos alongside her mother.

While Pour Lui frequently had tensions with early members of BiS, especially Terashima Yufu, whom she hated, she was usually on good terms with the members from 2013 to 2014, of whom she still remains friends.

In early 2019, Pour Lui was photographed with KEYTALK member Ono Takemasa, prompting reports that the two were dating.

She has a pet dog called Kotarou.
