Find an animated film about Libra!

This should be it. I remember several episodes in which my brother and younger brother really quarreled because of their incompatible personalities.

Here's the story. In order to become the patron saint of the universe, the little angel Cupid must go to the twelve constellations within one year and get the "town seat" token of each constellation from every teacher in charge of constellation tokens. Only when he got twelve tokens and was baptized by twelve constellations symbolizing human personality characteristics can he be officially appointed as the patron saint of the universe. But Libra's two brothers don't get along, and he can't get the token, so he is trying to make the two brothers reconciled. That's about it. See if it's true.

I have seen this animation. It's actually quite fun. You can watch it even if it's not.
