Biography[edit | edit source]

2018[edit | edit source]

From March 12 to 18th, 2018, Muropanako took part in the WACK Audition Camp 2018 under the name "Ayuna C".

At the concluding WACK EXHiBiTiON on March 18th it was announced that Muropanako had passed the audition and would be joining BiS 2nd.

Muropanako's first single with BiS, Don't miss it!!, was released on July 4th.

On July 26th, Muropanako was added to the shuffle unit HOLY SHiTS, and her debut song with the group was released the same day.

On July 30th, Muropanako ranked 8th in the first BiS.LEAGUE election and remained in BiS 2nd. Afterward, she was given the title of BiS 2nd's captain.

On December 29th, Muropanako ranked 9th in the second BiS.LEAGUE. While she was not demoted as BiS.LEAGUE was announced to end, due to her low ranking, Watanabe Junnosuke singled her out as being "unfit to perform as part of BiS" and at risk of being removed from the group.

2020[edit | edit source]

From the 24th to 30th March 2019, Muropanako took part in the WACK AUDiTiON CAMP 2019, under the condition that any BiS members taking part in the boot camp would be removed from the group if they were eliminated.

On March 30th, while Muropanako had passed the audition camp, BiS announced their intention to disband anyway, in response to the firings of Aya Eightprince and Toriaez Hana, who had been eliminated.

When BiS disbanded on May 11th, Muropanako announced that she would remain in WACK.

On June 24th, Muropanako revealed on her twitter that she had changed her mind about staying in WACK, and had ended her contract. She deleted her account less than an hour later. Soon after, Muropanako opened up a new twitter under her real given name, Hanako.

2020[edit | edit source]

On March 13th, Hanako announced that she was starting a new music project, named Her knuckle, which would be releasing the music video for its debut single two days later.

Hanako's first two digital releases with Her knuckle, Lemon Hata no Kyouryuu and Meury were simultaneously released on May 6th.

Personal Life[edit | edit source]

Hanako is a close childhood friend of Ayuni D, and they attended the same school.

On July 30th, 2020, Hanako announced that she had been diagnosed with ADHD.

Trivia[edit | edit source]

  • During the audition camp, there were rumours that Muropanako was actually Ayuni D's older sister.
  • Her audition name, "Ayuna C", was a parody of Ayuni D.
  • She considered Ayuni D to be her rival within WACK.
  • Enjoys video games, especially Dragon Quest, and frequently wears gaming merchandise.
  • Her catchphrase, "Parupunte!" and her role, "And so, the Legend Begins", are both references to Dragon Quest 3.
  • Her favourite senpai was Go Zeela.
  • Muropanako was the only second generation BiS member remaining in WACK that did not join CARRY LOOSE. It was speculated that this may have been a factor in her decision to leave WACK, as she had been liking and sharing tweets about distrusting adults on the day that the group was announced.
