8화: Happy Around!가 U4 Fes 등록 코드를 찾느라 고군분투

8

Rei reminds Happy Around! about signing up for U4 Fes., especially as they had reached the deadline, but the four are still unable to figure out how to do so. The other units recall finding a QR code watermarked in the invitation that leads to a registration website, though through varying methods: Peaky P-key simply noticed the code, Photon Maiden held the sheet by a stove and the heat exposed it, Rondo solved a puzzle, Rika spilled water on Merm4id's, while Lyrical Lily refuses to disclose how they found it. After Happy Around! attempts each strategy to no avail, Rinku notices the invitation has two sheets, the second of which contains the code. However, they are quickly annoyed when the website requires them to find an alien in a crowd of people before continuing. (Source: Wikipedia)
