Apparently, Yukari and Suika had met ever since IaMP. Ran was with Yukari at that time. So I should say Ran and Suika are practically acquaintances until UDoALG.
Hey, Ran~! What do you mean I smell like Zanmu? Ya tryna' say I stink!?I was talking about the unique smell of the oni of hell....the smell of someone as strong as you...!Do strong people always smell like they haven't bathed?
