La Féerie d'une Nuit

is the Noble Phantasm of Charlotte Corday in her swimsuit. 
A Noble Phantasm that simultaneously bewitches and attacks with a magic show.
Usually, with her skill level, it should be at best D-rank in destructive power and E-rank in illusionary power, but the synergy between her skills and her enigmatic angel (provisional name) can make this a devastating attack.
