The group was formed in phases:
- On December 2015, six different configurations were offered to be chosen from.
- On January 2016, the unit compositions were revealed, and people were asked to submit names for them.
- On March 2016, the choices for unit names were revealed.
- On April 2016, the chosen unit names were revealed.
Due to the image presented by the members, many of the name submissions had a dark or gothic feel to them.
Guilty Kiss' name was meant to symbolize the slightly grown-up and little devil-like image the unit has.
Other highlighted submissions are "RYM," and "Chrom Cross."
Their group introduction goes: 「愛こそ全て、Ｇｕｉｌｔｙ Ｋｉｓｓ」"Ai koso subete, Guilty Kiss", which translates to "Love is everything, Guilty Kiss".
