Sou x Uchiage Hanabi
爽x打ち上げ花火~
In the video, Nazuna Oikawa (voiced by Suzu Hirose) looks at the viewer and asks if they'd like a bite of Lotte ice cream. The first-person perspective also ties in to the "Sayaka Happy! Hanabi Kanshō 360°" virtual reality application. Users can scan Sayaka Lotte product packages with their smartphones to download the application. The app will show 360-degrees worth of fireworks with Nazuna, who will say five different phrases.
