A little update: My friend Yuki-chan (maid cosplayer) is asking if I would go to Nihongo Fiesta, will be held at Skydome. Unfortunately, it's the same day as UP AME. This clearly shows something I haven't mentioned before about Philippine anime cons - there appears to be an unspoken rivalry between large sponsors. They sometimes schedule their event on the same day as another group.
Something completely unexpected today. There's no anime convention. I was just casually going home from a mall today on a public jeep (we have those long jeeps here that are used as public transport vehicles). Halfway through the trip. A Kagome cosplayer flagged the jeep and she went aboard. I'm sure she's a cosplayer because the bow is in her bag.
After consulting with my cosplayer friends. It's decided that the cosplayer I encountered is probably just going home from a photoshoot. Since there's no known convention today. I guess cosplaying is becoming a little more popular here.
