Context: Libatape is a brand of japanese Band-Aids.
Though why doesn't Miho know about it, but Saori does. Is it Miho's Kumamoto upbringing? Or perhaps is it that traditional households (e.g. Nishizumi) forgo the use of foreign brands, and only use Japanese brands for everything?
Also, Anzu doesn't seem to know anything about Libatape, so is it a small brand?
