Yet again, a pun that doesn't translate that well into English.
Bunny-cartoon-thing says something to the effect of "Let's make photo club more exciting together!"
...but Kiyomi misreads it as "Let's make a pile (of something) in the photo club together!" due to the verb meaning two things depending on the context.
What just happened...?Don't Say It!then Kiyomi should definitely...With photographs...?Uhh... well, that is...If it was anyone else but since you're the one asking Iinchou if all you need is a name on your sheet then I guess that's not too much to ask!Why don't you join, too, Riko?Uhh... I'm not really much for clubs...I've actually wondered about that, Sawatari... why haven't you joined a club?Kor--Unknown LifeformsThe next day...Photography Club?...that's right! If it's photography,Let's pile on the excitement in the Photography Club together!*twitch*Photography Club: Now Recruiting
