Where are you coming from ouo?
There are certainly many!
I would recommend Comic Party in Central World on the 14-15th of August. As Touya Hibiki will be there >//>
Though Idealistic Novelist Grand Cosplay on the 22nd will have Yuegene, Yolk and lots of other famous cos'ers will be there http://www.cosbook.in.th/grandcosplay/?cat=3
If you'll go to either of the two, I'll be going as well ^^ Hope to see you there na~
