Biography
Lest first appears in chapter 3 and returns as the protagonist of chapter 7

He wakes up in company of Tarsa on a beach in the Noah region. The two persons realize that they're in the same predicament as both have been sucked in by a black vortex. They then introduce themselves to each other, and decide to search for a human village. When he remarks that Tarsa's outfit is quite sexy, she teases him a little.

As they move through the cove, they get attacked by a Mermaid. After fighting her back, Lest says that they must stand on their guard, while Tarsa wonders if Novissa is close by. As they discuss slightly later, he realizes that he and Tarsa could be from two different worlds. As they reach the end of the beach, they notice a sign pointing to Grangold. The duo hopes that it will lead them to a large settlement. As soon as they enter the cave, they meet the White Rabbit who explains them the situation about the Seven Heroes, Proof of Collaboration, and the "Queen of Dreams". They believe the White Rabbit, and continue on their route to a human settlement.

The duo comes across a pair of adventurers who offer them to take a break. They learn that the Grand Noah Queen offers a substantial reward to anybody who brings information about parallel world, but she's apparently gone slightly crazy. Lest accepts the adventurer's offer to rest, although he remains wary. When he notices that they're not here when they get up, Tarsa inform them that they left before dawn and that she has already eaten.

The party comes across a priest, who transform their past experience into job. At the end of the cave, the party meets a Devil Fighter, sent by the alliance of the Queen of Dreams. The duo manages to dispatch them, and continue toward Grand Noah.

However, before they can reach the city of Grand Noah, the duo gets attacked by Bell and Lyla. The heroes manage to push the two monsters back, and successfully enter Grand Noah to be greeted by the queen. However, the latter tells them that they don't need heroes. The duo soon realizes that the queen has been brainwashed by Musette, but before they can do anything, Tarsa's succubus blood is awakened and she violates Lest unconscious.

Lest wakes up in Grand Noah's prison a bit later, and finds a diary informing him of an escape route. After recovering his equipment, he starts escaping the prison while fighting avoiding Automata Girls. However, he's soon blocked by a large number of them, but is saved by an intervention of Novissa who is looking for Tarsa. He explains to his savior what happened, and the latter joins him. As the party searches for Tarsa, they learn that she's been brought in deeper. After getting the key to the lower floor by fighting the warden, the duo is more determined to find Tarsa and restore this country.

After scouring much of the prison, the duo finds Tarsa sucking men dry for a ritual to bring in the Château des Romances. They beat her to bring her back to her senses, but before they can celebrate, Musette steps in and engage the party into a fight. Even after being beaten, she still forces the summoning of the castle, trapping the party who gets surrounded by Nightmares.
