Levi's Unknown Cleaning...

is an extra chapter of the Attack on Titan: No Regrets manga, written by Gun Snark and illustrated by Hikaru Suruga.

== Overview ==
Furlan tells Isabel a horror story and at night, she is frightened by a stain on the ceiling. Levi, who was above, falls in Isabel's room, making her believe he is the monster of Furlan's story. They later clean the mess in her room.
== Summary ==
Late at night, Isabel rests nervously in her bed, recalling a time from earlier that night when Furlan told her of a scythe-wielding monster that comes out on humid nights like that night. Furlan is amused at how easily he spooked Isabel.
In her bed, Isabel stares nervously at a stain on the ceiling above her, seeing the face of a ghoulish monster. On the floor above, Levi notices one of the barrels is leaking its liquid onto the floor. As he grabs the barrel, the floor beneath him gives way, sending him falling into Isabel's room. Isabel leaps out of bed, equipped with her vertical maneuvering equipment. As Levi asks her what is going on, she panics, thinking that he is the monster as Furlan hurries into the room. Shortly afterward, Isabel is cleaning the mess while Furlan looks up at the hole in the roof and Levi sneers at his dirtied clothes.
