S1·E2 The Eizouken Takes the Stage!

As Mizusaki is banned from joining the anime club by her parents, the only way for the three of them to make anime is to set up a new club. At the staff room, their teacher tells them that they will be granted a certain budget if the objective of their club was to create a live-action movie. Kanamori suggest that they will call their club "Eizou (Film) club" and use its name as a disguise. Thus "Eizou-ken" came into existence! They head off to a storage space previously used by the anime club and realized all kinds of treasures behind the door!
