Kogasa, you go to karaoke too often!

Is there a leak in your karaokenium tank or something?

Well, the thing about karaokenium, see...

I'll have a full tank of it right after I'm done singing...

Whoof, now that was satisfying.♡

Time to head home!

Hm...seems like I didn't sing quite enough...

...and then it drastically depletes the instant I leave the room!
