Echorin-P

Echorin has light purple hair. It resembles a jellyfish haircut with tomboyish sidetails. She keeps the long hair tied up in two low twintails. She has slight heterochromia, with her right eye being red, while the left one is a dark pink. Echo wears a poofy white dress with a purple-blue gradient. Around her collar she wears a bow tie, with her magical girl brooch attached to it. She also wears dark blue space themed gloves and stockings.

In her un-transformed state, known as "Mei Shirui", she is considerably taller at 168cm. Her hair is a natural dark brown, becoming wavy towards the ends. Her eyes are drastically different as they lose the heterochromia effect - Instead they are both a bright, piercing shade of blue. Dark circles are present underneath them, with her resting expression to be somewhat tired. She describes herself as having a natural "resting bitchface". Her chest also increases in size noticeably. Mei Shirui currently has a 3D model serving as a temporary model, with a Live2D model under production for the future.

Echorin's debut was on 5 March 2022. She started with a PNG model and made variety content.

On 6 March 2023 she released her first cover "Lagtrain" by Inabakumori.

• Her fans are known as "Chochodachis". They are fluffy little creatures with butterfly wings. It is said they take this form due to magical girl radiation. If someone is exposed to Echorin's energy for too long, they will morph into said creatures. They are summoned to empower the magical girl with magical mana they hold inside their small body.

• Echorin is a magical girl that got her powers from a God called "K-chan". Why K-chan granted her the wish of becoming a magical girl is currently unknown. Her non-magical girl form looks very different from her transformed version, and is a lot gloomier.
