Washed ~Bonds of Battlefield~

Summary
The chapter starts out in the Yuuki household, with Rito finishing up cleaning the toilet as part of his daily chores, with the bathtub being next on his to-do list.

He hears the doorbell go off, and goes to answer it. Much to his surprise, Haruna is at the door. Lala walls in, explaining that she invited Haruna over to bake cake with her. They invite Rito to join them, but he declines, as he still has chores to do. As he starts walking to the bathroom, Lala shows Haruna her newest invention, albeit one that isn’t fully ready for use: a device which can turn anything it touches into sponge cake. Rito, knowing very well the history of Lala’s Inventions, takes it from her, telling her he’s holding onto it until she tests it more to prevent more catastrophes. While Lala is upset by this (“Rito, you meanie...”), Haryana thinks to herself that Rito May have just made a great decision.

As Rito cleans the bathtub, Momo walks in, and asks him to go into the kitchen and spend time with Lala and Haruna. She purposefully presses her chest against his back, embarrassing him. She begins to tease him, claiming he still has no resilience to his arousal and nervousness at the female form. Overwhelmed, Rito moves away from her, and lands on Lala’s nearby invention, which he had set down next to him.

After a flash of bright light envelopes Rito, Momo stares in shock at what has just happened. In Rito’s place, next to a pile of his previously worn clothes, now lays a sponge.

The sponge (Rito), unsure of what just happened, begins to panic, asking Momo what happened to him, though no words come out. Momo picks the sponge-Rito up, and deduces that since the invention was designed to make sponge cake but wasn’t completed, it’s only able to turn things into body sponges, much to Rito’s disbelief and horror.

Meanwhile, in the kitchen, Lala and Haruna find themselves covered in a soot-like substance after Lala attempts to add dark matter to their cake batter in order to make it taste better. They both agree to go take a shower and get cleaned off before they continue cooking. Momo, who sees this as an opportunity to help Rito grow more comfortable with the female form, leaves him in his sponge-form out in the open and exits the bathroom before Lala and Haruna arrive.

As Rito begins to worry about what Momo just did and what her intentions were, Lala and Haruna enter the bathroom and begin to undress, unbeknownst to them, in front of Rito. Rito proceeds to panic as he watches the two strip naked, and quickly figures out what is going to happen next.

Soon after,
