Himitsu no Akko-chan: Umi da! Obake da!! Natsu Matsuri

Collection of series that feature Ondo songs as a theme songs or as part of the series.

Includes all* anime on the Anime+/GRAPH mahou shoujo/magical girl achievement list

Notes:
If the anime is saved under a different name in the original list (and the ID matches), the listed title is added as a comment. The anime will keep its place according to the list - even if it will no longer be alphabetically correct according to its main title on MAL. This is to make the job of checking and updating these much easier for me.

*The main stacks do NOT include hentai. This is both for people who want to avoid it, and because including it will significantly limit the stack. Please proceed to the Hentai Edition™ in the list below if you're into that.
