After years of living in her own world of code and mecha battles, Shiku Tanaka never expected to find love—especially not after switching bodies with Cleansuke, the school's cleaning robot! Now she's rolling through the halls, accidentally collecting admirers faster than she can sort recyclables.

Amongst the admirers are Nezumi, the popular girl hiding her passion for mechs; Yuriko, the shy novelist with a flair for steamy stories; and Reiko, the tech heiress with a slight cosplay obsession. When all three start falling for Human-Cleansuke, things get messier than a classroom after art class!

Will Shiku find a way back to her body, or is she destined to spend the rest of high school cleaning up after her own romance?! The battle for love—and proper waste sorting—begins!
