Shugo Chara! Season 1 Episode 13 Episode 13 - Big Disturbance! New Year Live!

A group of students from Seiyo Elementary School, including protagonist Amu Hinamori, are eagerly preparing for their school's New Year Live event. Amu is excited to see her crush, Tadase Hotori, perform on stage, along with her classmates and their Guardian Characters. However, something strange is in the air as the students start to act out of character.

Amu's own Guardian Character, the spunky and energetic Ran, senses a dark aura surrounding the school and warns Amu to be careful. As Amu investigates, she discovers that a new Guardian Character has appeared and is causing havoc by taking control of the students' personalities. Worst of all, the new character has set its sights on Tadase.

Determined to stop this new threat, Amu transforms into her alter-ego, Amulet Heart, and comes face-to-face with the new Guardian Character. The two engage in a fierce battle, with Amulet Heart using her powers of transformation to try and gain the upper hand.

However, the new Guardian Character is proving to be a tough opponent, as it continues to manipulate the students and spread chaos throughout the school. Amu decides that she needs to enlist the help of her friends and their Guardian Characters if they are going to be able to put an end to this madness.

As the battle rages on, it becomes clear that the new Guardian Character is not acting on its own, but rather is being controlled by something much more sinister. Amu and her friends must work together to uncover the truth behind this disturbance and put a stop to it once and for all.

In the end, it is revealed that the new Guardian Character was actually created by a student who was feeling left out and neglected by her classmates. Through the power of friendship and understanding, Amu and her friends are able to bring everyone together and save the day.

As the New Year Live event finally takes place, Amu is able to enjoy it with her friends, knowing that they have overcome yet another challenge. With her Guardian Characters by her side, Amu is ready to face whatever the future holds.
