Kagurabachi joins Kao laundry campaign for student residences

Kao has launched its new Oh! Laundry Project with a campaign built around Kagurabachi, using a newly drawn image of protagonist Chihiro Rokuhira to teach laundry basics in student residences. The project began on 15 October and is scheduled to run until 8 January 2027.¹²

The collaboration is aimed at young people who are starting to do their own laundry. Kao says it visited university residences, inspected shared laundry rooms and spoke with students before developing the project. Its stated goal is to make laundry feel more approachable, with small practical choices presented as the difference between a frustrating wash and a better result.¹²

The key visual places Chihiro beside a laundry basket, recasting the Kagurabachi lead as an unlikely laundry guide. The official manga site says the campaign uses an original illustration by series creator Takeru Hokazono. It also pairs memorable panels from the manga with laundry advice in a set of posters titled “One Move Can Change Everything” with Kagurabachi.²

Those posters are being displayed in laundry rooms at several student residences, including halls connected with Kokugakuin University, Senshu University and other accommodation providers. Kao and the official Kagurabachi site also say that the campaign visual will be shared through social media, giving the project a digital component beyond the physical posters.¹²

The advice is presented through the manga's action imagery. Kao's campaign site uses examples such as blood, mud and food stains to explain why different marks need different treatment. Blood should be rinsed with water rather than hot water, dry mud should be removed before washing, and food stains may need immediate pre-treatment with a suitable oxygen bleach.¹

The official campaign material also covers less dramatic problems such as overloading a washing machine, using the correct amount of detergent and dealing with odour or colour fade. The Kagurabachi framing is deliberately playful: the series' battles provide the visual language, while Kao supplies the practical household guidance underneath it.¹

This is a brand campaign rather than a new manga story or anime announcement. Kagurabachi is being used as the attention-grabbing creative partner, with the project focused on laundry habits and Kao's fabric-care products. The manga's official announcement confirms that the first phase is a collaboration, rather than a change to the series itself.²

Our opinion

The campaign works because it gives genuinely ordinary advice a visual hook that its target audience already understands. A shared student laundry room is a natural place to offer help, and Chihiro's presence makes the posters more noticeable than a conventional detergent information sheet. The important part is that the collaboration keeps the practical message visible: the manga is the invitation to stop and look, while the stain-by-stain instructions are the reason the material has value.

It is also a useful example of how a manga partnership can stay specific. Kao has not simply put a logo beside a character image; it has matched the series' language of decisive “one move” moments to the small decisions that affect a wash. Whether that turns into lasting brand recall is impossible to judge yet, but the idea is more coherent than a generic character tie-in and should translate well to the student spaces where the campaign is appearing.
