Ugh... I was terribly sick for a long while on Sunday. v.v My stomach was very sour... and I doubt it was the coffee I drank that morning, because it lasted until around noon. .-.
That's why some people may have seen a rather uncomfortable/sick looking Naoto sitting around a lot. ><;
Dunno if it was the "pokepox" (XD ), since it hit a while after I got to the con that morning and went away so fast, but... =/
