Chuunibyou demo Koi ga Shitai! Ren

Synopsis

After Yuta is left reeling from a lewd dream about Rikka, he ends up losing a bet against her and is forced to dress up as a magical girl. Later that day, Rikka encounters the girl from before, who is revealed to be Yuta's old friend during middle school and the one who led him to enter his chunibyo phase, Satone Shichimiya. As Satone is invited over to dinner that night, Rikka becomes angry over her getting awfully clingy to Yuta, particularly when she does her old habit of rubbing her nose against Yuta's. After seeing Satone off, Yuta reassures Rikka by initiating a 'contract' of his own.
