Sunday is a busy day!
Tournament opens for freeplay at 10am, qualifiers start at 1pm.
Stream is announced for 18:00 JST but I imagine it will start much earlier.
If you visit the page it will show there are two channels, Nico and Ustream.
Join in to support the players and EU’s biggest DOA supporter, ON.Emperor Cow, will be entering too!
