Speaking of Eushully figures, the one (and only) Eushully figure I remember seeing was Sylphietta's from Meishoku no Reiki.
This one (might be NSFW? only if you click on the nudie naughty bits).
God, I remember that game's hilarious append content, where Sylphietta and Ignaat's daughter (the Lily prototype) made the Yuusha her bitch. Hahaha.
I don't really think any Eushully title would translate well to being an anime, or OVA for that matter.
