I find it funny that by how she's described in narration and by other characters, it's Mai who should be the thick one.
In general, May is described as thick but buff, Yuna as more or less chubby and Hanako as a total amazon, despite all of them looking like standard anime girls. It's shame since author can draw more diverse body shapes, as shown by the side characters like the thick senpai or the wrestling club.
