SAK (朔雀) is a Japanese artist credited in both romanized form and kanji, with the name written exactly this way in releases and music listings. The mixed-script credit preserves the original Japanese spelling while keeping the entry readable in English-language databases and search results.
That presentation is useful for catalog consistency, because it helps international listeners, collectors, and database users match the same artist across different listings. It also reduces confusion when the profile is indexed under both the romanized name and the kanji form.
For music libraries and anime databases, that kind of naming format matters because it makes the artist easier to locate without changing the original credit. SAK (朔雀) is therefore best identified by the exact mixed-script name used in the metadata, which keeps the profile clear, searchable, and consistent.
