Instant coffee.

Just add in boiling water then you can use it right away...

To think we have something like this today...it's great.

I think we had it for quite some time before but...

Hey Renko, can I try it?

No problem, I have a boiling pot here.

She's an Ojou-sama so it must be rare for her to see instant coffee.

Plus I can drink coffee made by Merry, lucky me!

Hihihi...

Wah, it's really done in an instant!

Here, enjoy!

Is it good?

It's delicious!
