Little Koharu-chan really freaked out over those games, didn't she!! Maybe we have a new phobia in the works, to compete with Rika's chicken-phobia. Koharu has "I'm blindfolded and there's random shit touching my head" phobia.
But Koha's not too little, she's only 12 yet and as tall as Rika at least!!!
I delight in the future rivalry between "I'm so cute" Sayu and "I'm cute without even having to shove it down everyone's throats" Koha.
