Next, just as they were about to film the music video for their new song in a single take, a countdown suddenly began. A video reviewing the five members' journey so far was projected onto the main hall of Zojoji Temple using projection mapping, and the words "KEY TO LIT to debut with a CD this winter from Universal Music!!" appeared on the screen.
The members were in a commotion, saying things like, "Huh, what is this?" and "We weren't told about this," indicating that it was a complete surprise. Igari Soya and Nakamura Reia exchanged hugs, and Iwasaki Taisho bowed deeply to the fans. The five of them hugged each other in a circle. Igari made a fist pump and shouted "Thank you!" in his natural voice, appearing unable to hold back tears.
Iwasaki announced in her own words, "I will be making my debut this winter with Universal Music!" She declared, "I'm so surprised I can't put it into words, but I truly feel that I'm able to make my CD debut thanks to everyone's support. I will do my best."
