In the manga and the anime series, sometimes a devil pops up from Izumi's head, and chickens from Wakana's head.
Izumi's devils seem an obvious allegory for the effects of
Sexual arousal on his private parts
But I am not sure about Wakana Ui's chickens.
Are those devils and chickens an allegory for their mental state? What is the meaning of Wakana Ui's chickens?
