Its a "Draw 4 Card"... The new color is green

Therefore, "Uno"

It's a real contest, this card game...

No hard feelings, huh, Rose? Then, draw four

Then... me too... The color is now red

* They're playing with the rule that allows Draw cards to be played over each other (to pass the combined effects to the next player)

Please don't hold it against me, Flash-senpai

In that case... I'll also... It's blue

Please don't let it get to you... Pisa-san...

Umm... then I will also... The color is yellow

And Uno

I-I guess this is a real contest, right? Ruler-san?
