What is the 22th Shugo Chara episode about?

Answer 1

Well, the 22nd episode is after Amu's teacher, Nikaidou, takes Amu's egg. The other school guardians help Amu find her eggs and on the way, they run into Utau and Saeki Nobuko (some spiritualist). Saeki can see the Guardian Characters and is scared to see them at first. However, she eventually agrees to help the Guardians and Amu in their search for the missing eggs. Utau also comes along because she doesn't like Nikaidou's methods. Saeki drives like a maniac and eventually finds Nikaidou. As the Guardians confront Nikaidou, Utau's manager, Yukari Sanjo, appears and scolds her, asking if Utau is fine with whatever happens to Ikuto. Utau Character Transforms with Il, becoming Lunatic Charm, and attacks the Guardians. Ikuto comes to help and Utau de-transforms upon seeing him. After a struggle, Ran and Miki are freed, but Su is still with Nikaidou. Nikaidou makes a deal with Amu: he will give her a chance to get Su back, but she has to come get Su from his laboratory.
