There's a common anime trope which consists of a friend group of four girls today in slice of life anime. Lucky Star is one of them. However, this one was quite different. Tsukasa revealed to the group accidentally that she enjoyed being a baby, and later on, Konata explored it and joined Tsukasa in being carefree and lazy. Oddly enough, Miyuki decided to let go for once and let someone else take care of her as a baby. For Kagami, it took a little convincing, but with some 'help', she eventually gave in and discovered she liked it. But who do you want to be in this friend group?

Konata: Lazy but passionate otaku. Often would like someone to do everything for her, but is very energetic during playtime. Kagami: Not as obsessed with the idea, but likes to let go sometimes as well as caring for the others. Often victim to Konata, but plays most with Tsukasa. Tsukasa: The cutest and gentlest out of the littles. Plays a lot with everyone, and is always looking for new toys to play with. Miyuki: Loves being taken care of. She's always happy as a little, but is the best carer out of everyone. Loves playtime almost as much as Tsukasa.
