Some a**hole from China thought that it's funny to post chinese version and even edited textless version without posting the original japanese version. It peeved me since I don't get chinese one bit so I decided to buy the japanese version from dlsite.

Cure Fontaine is slowly infected by Shindoine and finally transforms into demon of Byogens herself. Later she infects and corrupts her friends - Cure Grace and Cure Sparkle.

If you are interested in textless version, here is the link:

@Alpineintrovert sorry to be picky but could you put the artist and circle/groupe name in the title please

so it would be:
[Akuochisukii Kyoushitsu (Akuochisukii Sensei)] Yogosa reta seisen ~ akumu no hōkago ~

instead of:

Yogosa reta seisen ~ akumu no hōkago ~

sorry it just really annoys me

Edit: Thanks!!!
