Kawakami and Gentil I get, but what's Scarlet got to do with these two? I can't read the Japanese beyond "Powerful Tiara" so idk
All three were/are very thicc, both IRL and in uma form, and their IRL counterparts physically overpowered their rivals on multiple occasions (for lack of better terms)... Donna and DaSca even duked it out with the colts of their time.
