QQ Sweeper is a prequel to Motomi-sensei's latest manga Queen's Quality. It's amazing how the quality of art improved since Dengeki Daisy. I'm judging this manga from the perspective of a prequel, meaning - if there are things that are not entirely explained by the end of the last chapter or anything that can be deemed unsatisfactory - it will surely be explained later on in Queen's Quality. The story is great. It's a splash of Motomi-sensei's usual humour and light drama, with a tenderly developing romance, and a intriguing supernatural premise. The synopsis doesn't explain much, but the story is basically about exorcism anda secret(-ish) organization that helps cleansing people's hearts/spirits that are being possessed, while doing actual cleaning in people's houses at the same time (washing, scrubbing, etc.). It might sound weird, but the setting is really enjoyable. If you read and enjoyed Dengeki Daisy, then you will definitely like QQ Sweeper. The attention to detail both in the art and story is most notable. Needless to say, this manga has left me with highest expectations for Queen's Quality.
