12 year old Hanakoganei Hibari, has just graduated from her elementary school to join the junior highschool. [All the major female characters' name are made of (name of an area in Tokyo) + (a bird). A Japanese audience will not be expecting a very serious story as soon as the heroine's name is announced ^_^]
OPA dream of a young smiling boy is rudely interrupted by an alarm clock. It isn't the first time this has happened. She wonders if she has fallen in love.
SubtitleAt breakfast, she proudly shows her school uniform to her parents; it is her first day in the junior high. Her father casually, and perhaps a little naively, mentions that it's the sort of thing she should get a present for to celebrate. Hibari's wild enthusiasm to this idea scares him a little. Just then a TV ad of Patapi, an electrical educable pet, catches her attention. Now she knows what she wants! But her parents don't wait around for her to decide and leave home for work before Hibari can tell them what she wants.
On the way to school, Hibari meets her best friend, Sakurajousui Suzume [Suzume speaks in "extremely distorted" extremely polite Japanese. So everyone understands right away she is from a very rich family but not ordinary at all ^_^;;]. The fact they are rather late does not disturb Suzume. She always has her own way. Her Patapi, Franchesca, says good morning to Hibari, who is impressed to hear he already speaks. Suzume tells her that she modified the language-learning algorithm in his memory.
At school, another girl is showing her Patapi's physical ability. Suzume is not impressed at all but Hibari really is. She is determined to get a Patapi and show it off to her friends. However when the teacher comes in to start the induction ceremony, he declares that no Patapi are allowed in the school.
After school, Hibari and Suzume drop in at a game centre to play UFO catcher. A strange old man comes up behind Hibari when she's playing the game, and declares her knickers are rather childish ^_^;; Yet peeping seems not to be his main objective. He suggestively tells Hibari, "Your "prince" is waiting for you on the hill." [This guy speaks with an Osaka accent, BTW] Hibari imagines she hears her prince say, "Come on, my Anima Mundy." She runs for the hill.
There she sees the trees, the sunset and everything exactly as it was in her dream. Everything that is except the boy. Instead, a ball of light falls down from the sky into her hands. It turns out to be a Patapi! She is jubilant to get her Patapi from her prince!!!
Back at home, she tries to name her Patapi. She lists names [rather old-fashioned ones only] and the Patapi reacts to one of them; Densuke. Yes, he is Densuke from now on.
Eye-CatcherHibari shows Densuke and explains what happened to Suzume next day at school. Suzume cannot believe such a dream-like story but is rather more concerned that Hibari has broken the school rule to bring Densuke to the school. Hibari is optimistic, "It'll be all right. Won't it, Densuke?" Suzume is appalled with the name; her Patapi's name - Franchesca Leopard Classic Renoir Sanhasha III [^o^;;] - is far more sophisticated. But Hibari is unmoved because he reacted to the name last night! But... not now. He shows no reaction whatsoever. Suzume observes there is no manufacturer's name on him; it could be a bootleg!
The teacher comes in and starts taking the register. While Hibari is pondering over her Patapi, Densuke suddenly starts to make noise. She is more than pleased to hear it but her teacher isn't.
After the lessons, Hibari heads for the teacher's room to apologise and reclaim Densuke but sees the teacher in a corridor. He tells her that the School Master wants to see her with her Patapi.
She meekly visits the Master's room. The Master asks her two seemingly unimportant questions. "Are you Hanakoganei Hibari? Do you like this city, Akihabara?" Hibari's "Yes" is all he needed. She is released without any punishment.
Hibari is walking down a corridor back to the classroom. She is confused with all of this but cannot complain as she has got Densuke back without much trouble. Then she sees a boy, very much like her "prince." She chases him without success but is happy enough to know he is in the same school.
Hibari, being late after everything she's gone through, decides to make a short cut on her way home. In a alley, she crashes into some rubber cushions... no, they are breast of a woman. "How enormous!" ^_^;; This woman knows her name and that she has a Patapi in her bag. She says she is going to confiscate it as Hibari has broken the school rule. Hibari is not convinced by this weird woman [who would!? ^_^;;] and runs away. Of course, the strange woman is not kind enough to let her go. She throws three pins to the ground around Hibari to create three monsters, Homunculi, and orders them to take the Patapi from her. Hibari, however, somehow manages to fend them off so the woman summons a more powerful monster (or robot), Cerberus.
Hibari has no intension of giving Densuke up. Densuke is a gift from her prince and still has a lot to learn. As she becomes even more emotional -fearful and angry-, Densuke starts to shine and transforms into a woman soldier. "Is that me?" Yes, the soldier has some resemblance to Hibari but is far more grown up.
The weird woman seems to be alarmed. "Is that Deva that Sir Shooting Star was talking about?" Deva beats the Homunculi easily and Cerberus is no match, either. Hibari is totally at a loss; "Who... who are you!?"
EDA boy with angel-like wings sleeps up in space while down on Earth, the weird woman, Blood Falcon, reports her failure to her master, who does not seem particularly worried. "Oh, has it already started!? No matter, it will be from now on that really counts."
