• Portal — yes Rakujitsu no Pathos is a Japanese manga series written and illustrated by Tsuya Tsuya. It has been serialized in Akita Shoten's seinen manga magazine Bessatsu Young Champion since November 2014.

In a quiet residential district of Tokyo, far from the city's bustling nightlife, Aki Fujiwara—an aspiring manga artist—lives a modest life. One day, his former high school teacher, Makoto Nakaima, moves into the neighboring apartment. The two are pleasantly surprised by the unexpected reunion. That night, however, Aki overhears unmistakable moans of sexual pleasure emanating from Makoto's room. Unable to suppress his curiosity, he peers inside and witnesses her having sex with her husband. This discovery marks the beginning of a clandestine relationship between the two, as their interactions grow increasingly intimate and transgress the boundaries of their former student-teacher dynamic.
