That last pic is a little
misleading, but yeah, I'm not sure what to say. Kitahara's official profile
says that she's 163cm, which puts her at 5'4". Yossui's official profile
doesn't list a height, but wiki
says 164cm. Obviously one of these two numbers is wrong... likely Kitahara's, since I remember Yossui being listed as 164cm since her MM days.
There's no arguing with this pic, though.
They're both in flat shoes, both are standing up straight.. and Kitahara's definitely got a couple inches on Yossui. Granted, Yurina will dwarf them both.
