Ep 22. A Flash of Sloth

Subaru and Rem are traveling by carriage after completing their trip to the village. On their way back, they decide to make a stop at the Mathers mansion. They are warmly welcomed by the estate's caretakers, Frederica Baumann and Petra Leyte, who appear to be hiding something. Later that night, Subaru has a nightmare about an unknown woman who cautions him to leave the estate immediately.

The next day, Subaru and Rem explore the mansion while Frederica and Petra are out. However, they soon realize that all the exits are blocked by an invisible barrier. They quickly come to the realization that there is no escape, and the mansion is infested with sloth-threatening spirits. These spirits wield immense power over time, making it next to impossible for Subaru and Rem to take them down. The two of them must use all their wit and courage to find a way to escape the mansion before the spirits consume them.

As they struggle to find a way out, Subaru and Rem encounter multiple traps set by the spirits. With every step they take, the spirits get stronger, and the two of them become weaker. Soon, the spirits begin to take advantage of their fear and start to manipulate and torment them with their past mistakes and doubts. As their spirits begin to dwindle, the two of them must put their trust in each other and fight to get out alive.

Rem, who has an unshakable bond with Subaru, does everything she can to lift his spirits. She reminds him of the importance of trust and friendship and encourages him to find the courage he needs to fight the spirits. Through her unwavering support, Subaru finds a way to break the spirits' hold over them, and they discover an exit from the mansion.

However, their struggles are not yet over. The two of them are ambushed by Betelgeuse, a powerful spirit that is the root of all the troubles in the mansion. Betelgeuse viciously attacks them both, revealing a terrifying plan to kill them and anyone connected to them. In this intense showdown, Subaru and Rem are forced to fight with everything they have to put a stop to Betelgeuse's plans.

As the battle comes to a close, Subaru emerges victorious. However, he is faced with another challenge when he discovers that Rem has disappeared. With his world thrown into chaos once more, Subaru must find a way to rescue his closest companion and continue his journey in this strange new world.
