Just over four and a half minutes into the short film, paneling appears in Doukyuusei.
First, the hands of guitarist Hikaru Kusakabe appear in an isolated panel, centered over black. Next, his band is shown with the lead singer thrashing wildly, the drummer’s hands and hair nearly a smear in the background. Finally, Hikaru is shown again, isolated and still, save his strumming hands.
In this moment, he’s thinking of his classmate — and soon-to-be significant other — Rihito Sajou. The band moves around him, but he’s lost in his own world, as shown by isolating his moving fingers in a panel and later, his still body in a full frame. Paneling is used a few times in Doukyuusei, always to display heightened emotion or to draw attention to the feelings of a specific character. It reminded me of the currently-airing series Scum’s Wish, which uses paneling as its primary visual technique.
