Soon, Kyubey appears at her window.

She lets him in.

'Hi Kaylee!  Are you ready to become a magical girl?'

'I'm... not totally sure.'

'I know it's scary, but the world needs more magical girls.  Plus, what if Lianne got hurt while hunting witches?  If you were just a normal girl you wouldn't be able to save her like she saved you.'

'I think you'd make a better magical girl than you think you will, Kaylee,' Kyubey says.  'You just have to wish to be a good person for the job, like we talked about doing.'

'...okay.'

She takes a seat on her bed, cross-legged.

Kyubey assumes a position opposite her, looking strangely formal for a weird alien cat.

'Do I have to say it out loud?'

He shakes his head.  'You have to say it, but it can be over telepathy.'

'Okay.'

She takes a deep breath, closes her eyes.

'I wish to be the sort of person who would make a good magical girl - someone who can face down witches without being afraid, and who can take fighting monsters in stride without panicking or - being constantly stressed out.'

Light, and wind, and something that is not quite pain.  White light emanating from Kyubey, and blue light emanating from her - 

Her outfit has changed.

She looks down at herself, sees stockings and long silk gloves, a frilly light blue skirt - twisting her neck around she thinks she can spot a blue bow on her back.  She's the perfect archetypal image of a magical girl.  She's wearing a silver tiara, with a cerulean gem set into the front that she's aware of like it's a part of her body.

She climbs off the bed, stands up.  She's lighter on her feat, every movement effortless.  She feels like she could hop from the driveway to the roof if she needed to.  Hesitantly she reaches out and unsheathes a narrow throwing dagger from thin air.

'You're a real magical girl now, Kaylee,' Kyubey says.  'Congratulations!'

'I feel different.'

'Magical girls are stronger and faster than ordinary humans,' Kyubey says.  'You need to be, in order to fight witches.  For now you should transform back, though, so you don't draw any attention.  Change your soul gem into its ring form - that's the jewel in your tiara.'

As soon as Kyubey tells her to do it, it's obvious that she can, and how.  She does: the magical girl outfit recedes and is replaced with normal clothes, the dagger disappears.  The gem becomes a tiny jewel set in an unobtrusive ring on her right hand.

'Ordinary people won't notice the ring if you don't want them to,' Kyubey says.  'But you shouldn't take it off.  Always keep your soul gem on your person.'

She nods.

'So... what now?'

'Well, you don't have to hunt right away,' Kyubey says.  'Your soul gem was just created, so it's still really fresh, and if Lianne will lend you any of her grief seeds you can use those to heal.  But you shouldn't put it off for too long.  I can help you on your first hunt, to find a witch that's not too strong for you.'

'I think I'd like that,' Kaylee says.

'Okay!  Let me know when you're ready to go on your first hunt.'

'I will.  I think for now I need to just - sit around and... process, I guess.'

'That's fine with me,' Kyubey says.  'Would you like company?'
