COO holding a cloth is tickled by REIKO.

Then AYUMU comes trying to take the cloth away from COO.

Of course, COO tries to keep it, but....

Watch your step!!

COO turns around the bar gaining too much impetus.

I almost fell down.
Did I laugh too much?

But COO is never tired of playing with REIKO:

"Tickle me again!!"

COO shows a strange laughing face.

"Let's pretend I'm not laughing anymore....."
