Volume 6: Chintsubu F
When Toride-chinko disappears one night, Ayase panics. The next morning, Hiro reveals that he has performed a successful remote exorcism on Toride-chinko, but when Toride-kun shows up at school with no memory of Ayase or the chinbi (chinko secret), Ayase tries to be optimistic about making Toride-kun fall for him all over again. What happened to Toride-chinko? Is he gone for good? Will Toride remember the chinbi and his feelings for Ayase?

Volume 7: Chintsubu G
In this installment of Chintsubu, Toride must come to terms with the fact that his chinko talks – and that it's fixated on Ayase. Ayase struggles to resurrect Toride's memories the only way he knows how: by working some hand magic on Toride-chinko. Unfortunately, he fails his mission and freaks Toride out in the process. Will Toride-kun be able to accept his wacky anatomy as anything other than a strange hallucination? Will he find the courage to talk to Ayase again, or will his fear of his over-excited appendage keep him down? This couple's drama gives Kamiya plenty of food for thought regarding his own relationship with Iwabuchi.
