Leo’s Sister

Ultraman Leia is the little princess of the Leo constellation in the L77 Nebula. Ever since she was little, Leo and Astra have treasured her like the apple of their eye. After impulsively leaving her homeland, she returns to find it reduced to ruins. Following a lead to Earth, she spots a familiar figure after the first monster appears. Though she isn't invited to join the MAC team, she quietly protects humanity from the sidelines, helping Leo. Once everything on Earth has settled, she arrives in the Land of Light and meets a rebellious young boy for the first time.

Leia: This kid is so rebellious. But if anyone wants to pick on my little apprentice, they'll have to get past me first.

Leo and Astra: When did our sweet, soft little sister turn into a black-sesame tangyuan? It's so hard to guess!

A story about family, not romance.
