MEANWHILE IN THE HOSPITAL

Geno: What is this object...

???: I'M FREEEEEEEEE!
Geno: Ugh...what is this pink smoke?!

???: YEAAAAAH! FREE!
So uh...who are you?
Geno: My name is Geno...and who are you? And what are you?? And what just happened???
???: You may call me Lily. I'm a demon from the underworld and well, long story short, I got blamed for something another demon did and got locked up in an orb for 1000 years and I didn't age for some reason. Anyways, I am very grateful to you! I'm not sure what I can do to pay you back...Just call me whenever you need something! Just say the magic sentence, and I'll appear! I can do a lot so don't hesitate to ask! Alright, see yaaaaa!
She disappears.
Geno: Uh...Lily? I need you right now! My friend is in danger! Please help him!
Lily: You need to say the magic sentence!
Geno: ...What's the magic sentence? I don't have time for this!
Lily: It's "Lily is awesome!"
Geno: ...Ugh. Lily is awesome!
She reappears.
Lily: WHY THANK YOUUU!
Alright, I'll go help your friend now!
She runs off to the hospital room.
Geno: What...what was that all about...?
