One
evening, Misao stays behind late at school to practice her piano playing.
She is eager to play the piece composed by her father, Shigeki Amano,
because he is due to return home after working overseas for several
years. Rumiya watches from his room in Ramia's house, glad to see that
Misao will have some much-deserved happiness in her life. Ramia, however,
is more determined than ever to beat Pretty Sammy — the scales of Gemini
are almost balanced, so this is her last chance. Rumiya wants to give
up and leave Misao to enjoy the weekend with her father. Ramia, naturally,
isn't interested in Rumiya's feelings, and sends him off to summon Pixy
Misa once more.
At school the next
day, Class 4-3 discuss what to do for the upcoming school festival.
Several ideas are suggested, but nobody can agree and the bell rings
before any decision is reached, so Miss Mihoshi suggests they all think
about it over the weekend. As Misao and Sasami walk home together, Kotoe
Amano, Misao's mother, pulls up alongside in her car. She tells Misao
that her father's flight has just landed. She has even bought plenty
of food for a special family meal, but seems annoyed about having to
take time off work. Suddenly she realises that she forgot to buy some
roses, Shigeki's favourite flower, and asks Misao to pick some up on
the way home.
As
Misao leaves the florist with a bouquet of red roses, she meets Rumiya
outside. He hypnotise her once again, promising that this will be the
last time he turns her into Pixy Misa. He tells Misa to use her maximum
magical power to create utter chaos in this, her final battle. She picks
up the bouquet of roses and uses her magical baton on them to create
an extra-powerful "Hyper Love-love Monster".
Sasami and her family
are eating dinner when Ryo-ohki senses a massive magical reaction. Washu
also spots it, picked up on her magic-sensing radar. Sasami, Ryo-ohki
and Washu all rush outside to see a huge rose monster laying waste to
the town! The enormous bloom unleashes a cloud of pollen over the entire
town. Sasami covers her mouth and nose to avoid breathing the pollen
and rushes back indoors. Inside, she finds her parents, normally completely
devoted to one another, arguing fiercely. The same sort of thing is
happening all over town — the cloud of pollen is filling everyone with
hatred! Looks like a job for Pretty Sammy...
On the road into
town, Shigeki's taxi is caught in a traffic jam, the police having closed
the roads. On hearing about the massive flower attacking the town, he
jumps out of the taxi and heads for the town on foot, worried about
his wife and daughter. Misao's mother also hears the news and sets out
to find Misao.
Meanwhile,
Sammy arrives at the disaster area to confront Pixy Misa. Misa attacks
using the giant flower's stems to wrap Sammy up. Washu, who is monitoring
the fight, is astonished to see that Misa's magical power is three
times
stronger than usual. It seems that Pixy Misa is finally going to fulfil
her mission and crush Pretty Sammy once and for all. As Misa goes
to
deliver her final blow, Shigeki runs onto the scene calling out for
Misao, and she stops in her tracks. Sammy notices Kotoe running towards
him as well, and worries that under the influence of the magic pollen
Misao's parents will fight with each other. With Misa distracted,
the
bonds holding Sammy loosen enough for her to break free, and they launch
into one-on-one combat. Shikegi calls Misao's name again, and once
again
Misa freezes. The emotion caused by seeing both her parents is enough
for Misao's memories to break through into her Pixy Misa persona.
Spotting
her opportunity, Sammy casts the Pretty Coquettish Bomber spell, destroying
the giant rose. 
As
Misa floats defeated to the ground, she reflects that roses should
not
be used to make people unhappy because roses are her father's favourite
flower. Sammy flies to the point where Misa landed and finds Misao
there
clutching Pixy Misa's magical baton. She finally realises that Misao
and Misa are one and the same. She drops her own baton in shock and
changes back into Sasami. Misao is devastated to discover that all
this
time she has been fighting with her best friend, and with a cry of
anguish she disappears.
