[4][6][7] In 2005, Shishido started collaborating with The High-Lows' drummer Kenji Ohshima and Uverworld producer Satoru Hiraide, and made a band called Eddy12 (stylized as eddy12) together.

[4] She was scouted before she started performing the drums as part of her act, but added them back in during discussions for how to set her apart from other musicians.

Since then, Shishido released three physical singles, "Aisuru Kakugo", "Music" and "Kiken na Futari".

[12] In September, it was announced that Shishido had switched labels to the newly created Justa Music, a sub-label of Avex Group, and would star in the second series of Erika Sawajiri fashion drama First Class.

[14] This song also serves as the leading track from K5, a special extended play where Shishido will collaborate with five different musicians, released in June 2015.

Shishido made her acting debut in the live action film adaptation of Ai Ore!

[3] Shishido also became the drummer for the house band on the KinKi Kids' variety show Shin Dōmoto Kyōdai in 2013.

[16] Since October 21, 2018 Shishido Kavka and Santiago Vazquez invite several musicians to an improvised presentation called "el tempo", which interacts with the public through hand signals, inspired by the events “LA BOMBA DE TIEMPO” and “LA GRANDE” that have been taking place since 2006 in Buenos Aires, where she grew up.
