The boy seems to be named Ikuto and he is a catboy. He throws his cat claws at Tadase and then Tadase dodges.

Ikuto's chibi flying thingy says that what Ikuto and him are doing is crap.  They leave.

So, Tadase saved Amu and now Amu is bleeding. Amu goes home. The little chibi flying things are called guardian characters, chara for short.

 The chara came because Amu wished to have a different personality and the chara helps her with that. The charas's name is Ran. At school the next day, Amu is praised for saying that she loved Tadase in public like that. Amu is invited to go to the royal garden, where all the guardians talk. The queen's chair, Nadeshiko, gives Amu a note from Tadase about the eggs.

Meanwhile, the second chara is born.  In gym class, Amu does better than anyone. The 2nd egg is not there anymore. In art class, amu usually draws horrible but know she draws good. I don't know why because Ran isn't an art guardian, she is a sports guardian. It was the 2nd egg! Her name is Miki. Amu chases Miki down. Miki is about to vanish because Amu doesn't want them. Amu tries to believe in Ran and Miki and they don't vanish. Ikuto is thinking that somewhere the character egg has returned. That is what Ikuto wants. A girl named Utau wants to get the embryo for him, which you don't know about yet. It's after school and Amu comes to the royal garden.

Amu Hinamori is a girl who has the reputation of a cool girl. Three eggs appear in her bed.

Okay, skip to the important part. These guardian ppl come and they find out she is a SPECIAL girl. Amu falls in love with one of them named Tadase. When she finally confesses, he says he already loves someone. She then runs away to a construction site and falls in a hole.

Amu sees a strange boy who actually happens to like her. Amu's eggs are on her side and the boy is evil sop he tries to steal them and happily touches her butt. The car thingy you use to pick up dirt clumps goes near them and almost buries them. The boy drops the eggs into the hole. A chibi thing pops out YAY! It makes Amu turn into a flying girl. The chibi person happens to be a guardian character, someone who guards ppl with eggs.  I'm really getting the feeling the boy has a crush on Amu. The boy comes close to Amu's face, but it is sadly interrupted by stupid Tadase.
