Don't worry, if Fiore tries anything nasty with Lyrisa's dead body, I'm sure that Leifr will execute his rapier-waifu in order to preserve what little honor witch-Lyrisa had left.
Clearly, magic is activate after a kiss and then a twirl, ending up with a shining, sparkling smile and a costume transformation. Mahou Shoujo Lyrisa, letsugo.
That being said, I wonder if Fiore would actually follow his other self's suggestion from a few pages back, after seeing Lyrisa actually be a magicky-person.
