Marine wanted some (Mario Tennis) coaching,

So I told her "sure, let's do a conference call!"

Okayu-senpaaaai!

And then it turned out Ao-kun came over to have fun at Marine's house that day!

During a match with Marine

Nice!

Yay!

Ao-kun...?

Nice!

Yay!

Okayu's imagination

Is it just me, or is Ao-kun going a bit wild?

Ah, no, not at all!

That's actually the Talking Flower's voice!

Nice shot!
