A group of [[Touhou]] characters commonly thought of as weak, childish, and plot-irrelevant.  Named after the chief member, [[Cirno]], who takes the moniker [[circled 9|⑨]].  Often drawn together doing childish things, or as students in [[Kamishirasawa Keine]]'s classroom. Known as バカルテット (bakarutetto) in Japanese, a portmanteau of "baka" and "quartet".
