In its simplest interpretation, "Kawaii" is a Japanese term meaning "cute," although there is an entire culture of this word, often important to young girls.
Ah, but here Byron has deliciously blended it into his story featuring Yumi and Kyuti, very cute gals in very aggressive boxing!
Byron has gone the extra measure here too, as in one version, the girls battling bare-chested and narrated by Yumi, and a version narrated by Kyuti, where the girls' breasts are partially covered by pasties.
This is the BRALESS version, which has four different panels plus two more than the "pasties" version.
