Luwi
The home planet of the Hikwiner executives and the central planet of an empire that controls multiple worlds.

Intro
Modern Japan, Kanadeoka City.
The invading organization Hikwiner, which seeks to rule the Earth by stealing the emotional energy "Happy," and the magical girls Lara Musica, who stop them, clash somewhere in the city again today.
Whenever Hikwiner executes a Happy collection operation, Lara Musica senses the abnormality and appears. Even if the city is damaged in the fierce battle, it is restored by magic once the fight ends. For the people living in Kanadeoka City, this has already become a common part of daily life.
Those who advance the Earth invasion. Those who stand against them as magical girls. Those who belong to either camp. Those who live their days unrelated to the battle.
Today, once again, the story begins from each of their perspectives.
