Fumu and Bun wake Kirby up one
morning to warn him about something, when Moso the postmaster
comes to deliver a letter. It's from Meta Knight, and he
challenges Kirby to a duel! It turns out this was exactly what
they wanted to warn him about, so they take him to Kabu canyon
to hide and reveal that they overheard Dedede ordering a
reluctant Meta Knight to fight him. Meanwhile, Tokkori informs
the village of what's going on.
But Meta Knight finds them and attacks Kirby with the flat of
his sword as a warning to what happens to those who aren't
prepared. Fumu and Bun tell him he's being unfair, so he
offers Kirby a sword as well. Their duel begins, with Kirby at
a disadvantage. Meta Knight knocks him around easily, and
Kirby is barely able to block or even fight back. Dedede and Escargon spy on them and see that
Kirby is unskilled in swordplay, and leave to order a demon
beast.
Meta Knight appears to use the battle as a chance to teach
Kirby, shouting advice at him and showing him how to use the
powerful Sword Beam technique. But when Kirby tries to focus,
he falls asleep. Before Meta Knight can attack, Fumu pushes a
boulder down, interrupting the duel and escaping with Kirby.
They hide, while Meta Knight realizes what Dedede is planning
and tries to find Kirby. Fumu and Bun wonder why Meta Knight
would want to protect Kirby. They realize they're near Kabu,
and ask him about Kirby. He tells them about how Nightmare
created a demon beast who did not obey, and they conclude it
must have been Kirby. When they ask how Kabu knows this, he
says he was told it by Meta Knight a long time ago.
Dedede orders the Gladiator Demon Beast, Bugzzy, and returns
to the canyon and chases the group. Kirby faces Bugzzy, but
it's all he can do to avoid being hit by the huge sword and
club it wields. He's unable to inhale it because it's too
large, but Fumu instead tells him to inhale its sword,
allowing him to become Sword Kirby.
Sword Kirby slices Bugzzy in half with a single Sword Beam, to the
delight of the villagers watching from the top of the canyon.
Dedede gets angry with Meta Knight for helping Kirby, but Meta
Knight insists that he's his loyal servant- and then kicks
Dedede's jeep down a cliff.
Meta Knight is still cryptic when Fumu presses him for more
information about Kirby, but she insists that they'll discover
Kirby's secret someday.
