Sasagawa Kyouko vs. Miura Haru is a Japanese music act credited under that exact name. The “vs.” wording points to a paired or collaboration-style credit rather than a standard solo project, and the punctuation is part of the official listing.
As a result, Sasagawa Kyouko vs. Miura Haru is best treated as a fixed catalog name for discographies, soundtrack references, and music databases where exact attribution matters. Its unusual structure makes the credit easy to spot in release listings even when little additional background is available.
