I'll get the Embryo!
In a dream, Diamond asks Amu if she knows what her true wish is. Thinking about this, Amu encounters Nikaidou and Yukari. Nikaidou informs Amu that the Embryo should appear tonight. While the Guardians celebrate the news, Easters sets plans in motion to trap Amu and capture the Embryo. Ikuto learns of the trap and frees Amu. Meanwhile, hundreds of search devices powered by X Eggs search the city for the Embryo but go out of control. Amu rejoins the Guardians and together, they purify the X Eggs. The Embryo appears among the eggs, and Amu and Ikuto jump to grab it. One of Easter's researchers controlling the search devices accidentally launches a shell towards Ikuto and Amu, but Ikuto blocks it. Kukai and Tadase rescue them before they could hit the ground. Tadase declares to Ikuto that Tadase will never give anything up to Ikuto. Ikuto grins and leaves.

Shugo Chara!
Amu Hinamori is a 5th grade transfer student who is fashionably cool, tough and independent. Despite this, she is also a girl who seems unapproachable, both at home and at school. In reality, the "Cool and Spicy" role she plays is just a facade that she unconsciously plays. With her guardian characters, she fights the Easter Company who is extracting people's eggs to create X Eggs & X Characters in search of a special egg called the Embryo.
