Concept / Plot

Hoshikuzu Witch Meruru Meru Akaboshi
Hoshikuzu Witch Meruru Meruru
This is a magical girl show that only exists in the anime "Ore no Imouto ga Konna ni Kawaii Wake ga Nai". It was broadcast on Thursdays at 5 PM, which puts it at
Hoshikuzu Witch Meruru Alpha Omega2
the same timeslot as "Maschera: Lament of a Fallen Beast". During the timeline of the first season of Oreimo, two seasons of the series were broadcast, the second of which was entitled Stardust☆Witch Meruru Double Heart. A third season, entitled Stardust Witch Meruru 3rd Impact, was announced during the second season of Oreimo.

Hoshikuzu Witch Meruru and Alpha Omega2
The plot centers on Meru Akahoshi, a grade four, 10-year-old student who magically transforms into Stardust Witch Meruru, whose duty is to defeat the dark witches, led by Thanatos Eros and her Octopus sidekick. Pretty Star and Evil Star, Comet-kun and Thantos Eros' homeworld respectively, has been in conflict for eons with Earth and Meruru being caught in the conflict. Dark Witches steals human bodies, especially those with innocent heart, as ideal vessels as they possess high levels of dark magic. This very reason is why they threaten to invade the Earth. Thanatos Eros chose baby as her vessel knowing that a baby possesses a pure and innocent soul.

Comet-kun made Meruru into a Stardust Witch to counter the Dark Witches threatening to invade the Earth. Meruru was chosen by Comet-kun due to the same reason why dark witches steal human bodies that Meruru posseses an innocent heart.

Meruru's best friend Arufa Kurotsuki, is Alpha Omega, a blue magical girl that seems is the rival of Meruru at first, but her partner later (Meruru launches a kind of purifier attack to Alpha in the opening).

Hoshikuzu Witch Meruru Dark Witch Meruru
By the third season of Stardust Witch Meruru, Meruru turns against Alpha Omega and an unknown magical girl and transforms into Dark Meruru with the help of someone who resembles Comet-kun, although having a black coat instead of Comet-kun's pink. Dark Meruru then reveals her powers, which include her strongest ability Planet Buster, which unleashes a beam of energy so powerful that it destroyed Earth in a single shot.
