It's
Sunday, and Sasami has invited Misao over to play. In actual fact, it's
the ever-energetic Sasami that does most of the playing, and Misao is
content to watch and enjoy being in Sasami's company. They take a break
for tea and cakes, and Professor Washu pays an uninvited visit, no doubt
still keeping a close eye on Sasami in her quest to investigate Pretty
Sammy.
That evening, Misao
returns home alone. As she finishes her piano practise, she looks around
her darkened, empty apartment and realises how just a short while ago
she was having such fun with her best friend. Misao begins to feel lonely,
and starts getting jumpy at every little noise, so she decides to call
Sasami for some emotional support. Sasami offers to sleep over, for
which Misao is very grateful. Sasami's helpful parents even have an
overnight bag and Sasami's satchel packed ready. As Sasami rushes off
to Misao's, Washu watches her leave, curious about where she is going
so late at night.
From
her usual spot in front of her view screen, Tsunami watches as Misao
and Sasami play cards before bed. Tsunami is impressed by Sasami's kindness,
and believes that she could even protect Misao if a ghost showed up.
This simple comment, however, gives Ramia a wicked idea, and she sends
Rumiya off once again to give Pixy Misa her next orders.
Later that night,
as she and Sasami are sleeping, Misao turns over and finds Misa's magical
baton in her bed. She hears a tapping at the window and turns to see
Rumiya waiting for her. Once again, he places her into an hypnotic trance...
A
little while later, Sasami wakes up to discover Misao is not in
her
bed. Worried if she is okay, Sasami gets up to look for Misao, but
finds that the lights are not working. She hears a moaning coming
from the
toilet and goes to investigate, but when she opens the door she is
greeted by a ghost! She rushes back to the bedroom to tell Ryo-ohki,
who sleepily
suggests that she should just transform and use some magic to get rid
of it. For once, Sasami is glad to have magical powers! However,
even
being Pretty Sammy doesn't stop her from being scared, and when the
ghost pops through the bedroom wall, she panics and runs up to the
apartment
block roof. Pixy Misa is waiting for her there, although she is about
the only thing Sammy isn't surprised to see. Putting two and two
together,
Sammy correctly guesses that Misa is responsible for creating the ghost,
but then goes on to accuse her of kidnapping Misao. Misa manages
to
convince Sammy that this is also true by ducking behind a screen and
rapidly changing back and forth between Misa and Misao, carrying
out
a crafty one-woman dialogue. Misa then tells Sammy that if she wants
to rescue Misao, she must fight her latest Love-love Monster, Ghost
Girl. Right on cue, Ghost Girl appears, and Misa commands her to possess
Sammy. Sammy backs away swinging her baton at the ghost, but without
a physical body there is nothing to hit! Just as Ghost Girl has Sammy
cornered, a jet-powered sleigh pulled by mechanical reindeer swoops
out of the sky and touches down on the roof. Its pilot jumps out and,
despite the unseasonable Santa disguise, Sammy has no trouble recognising
Professor Washu. 
Nevertheless,
Washu has a gift for Sammy; a device that can give ghosts a physical
form. Washu then steps back to collect some data and lets Sammy get
on with the fight. A press of the button on top of Washu's device
engulfs
Ghost Girl in an energy beam, and she emerges with a normal humanoid
body. Sammy casts her Pretty Coquettish Bomber spell and obliterates
Ghost Girl. Her job done, "Santa" thanks Sammy for all the
data she was able to collect, then flies off into the night. Misao
reappears
from behind Misa's screen, and has no memory of that night's events.
As Sasami and Misao
set off for school the next morning, Sasami is alarmed to see Washu's
jet sleigh and robot reindeer lying amongst the garbage. Sasami decides
not to make a big deal of it, and she and Misao rush off to school hand
in hand.
