I Heard the Idol Otaku is Dating His Fav

is a romantic story special featuring Kazumi Sawatari and Misora Isurugi, released alongside Kamen Rider Build NEW WORLD: Kamen Rider Grease.
==Synopsis==
It tells the story of a misunderstanding between Kazumi Sawatari and Misora Isurugi, which will eventually lead to Kazumi and the Hokuto Sanbagarasu on a self-searching adventure.
==Continuity and Placement==
The special takes place immediately before the events of Kamen Rider Build NEW WORLD: Kamen Rider Grease, as it places Kazumi and the trio on the island at the start of the film's events.
==Plot==
Kazumi is gleefully watching Misora work when she suddenly asks him to go out with her. Believing it to be a date, he puts on a suit and goes shopping with her, but is heartbroken when he learns that she only wanted him to help her find a present for her dad (although she leaves him with a gift, a free carabiner they had received while shopping). Frustrated & humiliated, Kazumi and the Sanbagarasu take an inflatable raft and go on an adventure, only to end up stranded on a remote island.
