Seto Utsumi v06 (Media Do)
A story that revolves around Kansai high school boys Seto and Utsumi -- particularly their completely normal but comedic chats after school.
This manga has been made into a movie and a TV drama in Japan."I wish we could just spend all our high school days sittin' and chattin' by this river." This seven-chapter volume is a collection of the funky, off-the-wall, and sometimes cynical after-school conversations between Seto and Utsumi, two high-schoolers from the Kansai region of Japan.
This series has been published in Japan since 2012 which Japanese title name is "Setoutsumi"
