Mahou Shoujo holoWitches!

In this world, is where the magical world of “Holocas World” exists, created when the light of people's hearts, “Holo” is gathered through the “Holocas” streaming app. The six protagonists: Kanata, Miko, Luna, Shion, Chloe, and Marine are usually active as “Holocas” streamers.

The “Yumeochi” phenomenon occurs when people who are anxious or stressed in their daily lives and have lost their positive attitude are sucked into the “Holocas World” with their souls. The “Collapser” monsters are birthed by a build-up of “Yumeochi". In order to defeat a "Collapser", these streamers are given the power to transform into magical girls called “holoWitches” and spend their days fighting to defeat Collapsers and save those who have fallen into a "Yumeochi" state.

What is “Yumeochi”? The story of these magical girls who fight against the dark forces and bring dreams and hope to people begins.
