Fulbeua

Fulbeua and Gilgorn battle theme

Fulbeua Sina Lestani appears during Collaboration Scenario. She comes from the game Succubus Rhapsodia with Lauratt, Rigeo and Gilgorn.

She's a Nightmare. She's also a complete narcissist, only liking herself and taking underhanded insults as compliments.

Biography
She first appears in chapter 5 in front of Lauratt, Rigeo and Magatsu. She reveals she's serving the Queen of Dreams simply to sate her ego. She also warns them that the Château des Romances will soon be brought to this world where Grand Noah is, as it is their plan. She then invites the party to hunt her before disappearing.

She shows up again in chapter 8 as the boss sitting on the throne of the Château des Romances itself, although reaching her first requires to shut down a magic barrier. Kazuya and Hakunen's party end up facing her and manage to keep her at bay. A dissatisfied Musette appears to order Fulbeua to finish the heroes off, which the latter refuse while Musette fails to brainwash her. The party then proceeds to exploit the confusion to escape the room.

In chapter 11, when the alliance of the Queen of Dreams gathers, she reveals that she does not care much about the latter's plans and intend to remain in the castle, only attacking the heroes should they show up.

In chapter 12, she indeed ends up being an obstacle on the Ninth Floor, and the party is forced to fight her as she simply does not care for anything but her own comfort, even as the castle around her is half collapsed and swallowed by a space-time distortion by now. When the party beats her, she tells them that she'll remain there and wish them good luck with Est. When everybody says that it's destiny that gathers them together, she sarcastically asks if they really think that.

She can be recruited in the post collab by facing her once again at the same place, and will ask for "something more beautiful than her" to join you afterward. The answer is to get the Mirror of Truth, an item used by Myusca, Nemea and Vinum in their own post-collab arc and acquired then. She will then join the party and gives Lauratt a rune to break Gilgorn's barrier, allowing the party to attack the Demon Lord and secure her traumatized self afterwards.

Chapter 8
A Nightmare boss, the major issue comes from your limited number of actually useful characters. Kazuya and Hakunen are limited to support roles, and even then they will only have a limited use. Otherwise, it's just a slog of spamming pleasure attacks, buffing and healing until she falls. Forget status effects, they don't work.

First and second Battle
Thankfully, with your whole party accessible and a teleportation crystal just in front of her, you can tailor your group to deal with her specifically. The fight itself remains the same boring slog of using pleasure attacks, buffing and healing up.

You have to fight her yet again with a +100 to all her stats after the collab to recruit her.
