You're welcome, glad to hear that you're excited for the upcoming content. But, the real thanks in this case should go to Threshold given their own affinity for fluff and Kitsunes. Although, I too share such inclinations, but I digress.
The method Volta provided works quite well, thank you very much for that, but there is another way to delete saves directly in game. On PC, if you hover your cursor over a save while in the load menu, just press the delete key on your keyboard and you'll be given a prompt to delete the save. So if you don't want to navigate through folders and such or just want to be certain which save you are deleting, you can use this method to delete saves directly while in game.
I do hope that you find this useful in the future,

Apologies for the delay, work has been a little busy the past few days. On Android you should have a bar along the top with elements like History, Skip, Auto, and Menu. You'll want to click Menu and then go into the Character tab. There you'll be able to access your inventory such as consumables, equipment, and key items. Once you navigate to your equipment, it should be a simple matter of selecting the runes and accessories you wish to use.
I do hope that you find this helpful and that you enjoy this title,

Now for the general update news, as it appears that all of the major bugs and notable balance issues have been reported and corrected, development focus will shift towards implementing Kotone's art and any new content that will accompany it, such as the planned jumbo tail scene that should have an accompanying massive fluffy tail variant of Kotone's character sprite. This will be a rather involved update even if it may not seem like much as implementing artwork is an intensive process, even more so for a character like Kotone due to the large amount of content she has and the sheer number of expressions and variants for her sprite such as fused or split tail, tail number, hand positions, and so on. It should be quite the treat as Threshold's usage of the sprite variants and expressions should help bring Kotone to life, especially considering how emotive she could potentially be.
I do hope that everyone interested in this information finds this at least a little useful.
