Judging from the mark on her face and Toyohime's possessions, I deduce Yorihime had a 'fan capable of inflicting mass destruction' shoved at her face.
And that fan was closed.
In other words, Yorihime's face just got poked so hard by Toyohime's fan that her face was turned inwards.
Reflect deeply on it!Onee-sama...
So, Onee-sama! Let's Hustle tonight!I think the Love Potion should take effect soon!I got drugged with a Love Potion instead! And that girl has no idea what going~!Night
