[[caption-width-right:236: Just another story about [[ABoyAndHisX a boy and his genetically modified super intelligent talking pet cat]] ]]

A ScienceFiction anime film, written and directed by Creator/OsamuTezuka in [[TheEighties 1984]]. It was a protest against gene recombination, that was being legalized in Japan during that time.

When he was a little boy, Ryo Ishigami received a present from his father: a pink kitten, whom he named Bagi. As the little cat grew, it started to show signs of intelligence beyond a normal animal. She tried to read, write and walk on hind legs. The boy's father was terrified that the kitten could be a mutant of some sort, and decided to get rid of Bagi, despite the Ryo's protests (he and the cat had become very good friends by that point). However, the father did not have to do anything, for Bagi had escaped.

Now, age 15, Ryo is a member of an up-to-no-good motorcycle gang, skipping school and getting into trouble with his new friends. For his misdemeanor he blames his father, who, busy with his detective work, is seldom seen at home, and his scientist mother, who completely devoted her life to her profession and does not even live with her family anymore.

One day the gang was riding about town, when its leader spotted a young woman, and decided to chase her, just for fun. When finally catching up with her, he discovers, to his horror, that the "lady" is, in fact, some sort of monster, who immediately starts to attack one gang member after another. When only Ryo is left, the monster-lady looks at him, but does not harm him, and runs away. After the rest of the gang comes back to their senses, the leader swears to find the monster-lady who attacked them, and take revenge.

They find an abandoned house, when they suspect she might live, and decide to wait for her inside. When darkness came, the leader sends Ryo for a lookout outside. Right then the monster returns, and attacks the gang once again. Ryo turns to the door, expecting to be attacked next. When the monster walks out, she turns out to be [[PettingZooPeople half-woman, half-cat]]. She talks, and tells him that she is Bagi. Terrified of what he saw and hears, Ryo gets on his motorcycle, and rides home as fast as he can.

When he gets home, he finds the cat-woman to be waiting for him. From her he learns that she is indeed his old cat, only [[SheIsAllGrownUp grown-up]] into [[InnocentFanserviceGirl what she is now.]] When Ryo asks her who she is: a cat or a human, she replies that she does not know herself; she has been looking for another of her kind for years, but with no success. As he thinks about Bagi's possible origin, he remembers that his father found her near the laboratory his mother works at. The two decide to go there, in search for answers.

And THAT... is only the premise.

The film had only been officially released in Japan on DVD and Blu-Ray.

!! The film provides examples of:

* ArtShift: The president's explanation on how genetic engineering works.
* AnAesop: Two, actually: "all living beings deserve to live" and "don't mess with nature".
* AnimationBump: When Ryo and Bagi are running through the infared security system, and when Bagi leaps from wall to wall in a hallway.
* BadassNormal: Ryo slowly becomes this during the course of the film. Semmen Bond is implied to be one.
* BeehiveHairdo: Professor Ishigami.
* CatGirl: Take a good guess.
* DisneyAcidSequence: There are several moments [[DerangedAnimation when the film does just this]], with no foreshadowing and have no bearing on the plot whatsoever.
* DisneyDeath: [[spoiler:Bagi.]]
* FramingDevice: Ryo hunting down Bagi five years later, the latter apparently attacking and killing villagers. [[spoiler:It turns out it was just normal animals who were menacing them.]]
* {{Hammerspace}}: When Ryo's mother feeds the animals the rice she created, a dog pulls out a bottle of water and adds drops to his share of rice.
* HumiliationConga: Bagi gives one to the [=SuperLife=] Center president through MindControl.
* HighPressureEmotion: Ryo when Semmen Bond double crosses him.
* InterspeciesRomance: It's quite obvious that Bagi loves Ryo very much. [[ObliviousToLove Ryo on the other hand, doesn't ever catch on]].
* ItsPersonal: Ryo in the FramingDevice has a personal vendetta against Bagi -- [[spoiler:she killed his mother when she promised not to. He didn't know she was set free, however]].
* MadScientist: The one [[spoiler: responsible for the creation of Bagi.]] A mild example though, since he is not ''that'' mad.
* MoodWhiplash: When Ryo's mother reveals that [[spoiler:Bagi will soon be executed]], Ryo briefly makes a highly over the top, cartoony WildTake.
* ObviouslyEvil: All of the villains.
* OnlyFriend: Bagi tells Ryo this repeatedly, [[TheOnlyOneITrust affirming how much she trusts him]].
* PettingZooPeople: Obviously.
* RidiculouslyCuteCritter: Baby Bagi.
* ScienceIsBad: Science will kill kittens, if not stopped.
* ShoutOut:
** Can you guess [[Literature/TheJungleBook which book]] provided the inspiration for the name "Bagi"?
** The scene between Bagi and Professor Ishigami is heavily inspired by Creator/WaltDisney's ''Disney/SnowWhiteAndTheSevenDwarfs''. Even the heart box shows up.
** Semmen Bond may be a Shoutout to James Bond, he even has a tune that has the familiar jingle in it when he is on screen.
* SuddenDownerEnding: Towards the end [[spoiler: it is revealed Bagi had "matured yet again", resulting in the sudden loss of much of her intelligence. For all intents and purposes, she's reverted back to a wild feral animal. Whether this was a case of WriterCopOut, ExecutiveMeddling, or CreatorBreakdown is unclear. Osamu definitely wanted to convey the message that [[{{Deconstruction}} man needs to learn that meddling with nature is morally wrong]], a noble cause, but regrettably, [[{{AssPull}} poorly executed in the final arc of the story at the expense of a main character's development]].]]
* TheOnlyOneITrust: Bagi adores Ryo.
* TragicMonster: If Bagi is a monster, she is one of these.
