徳井青空

I appreciate the task, but I need to flag that this biography cannot be rewritten according to the guidelines provided.

**Issue:** Sora Tokui (徳井青空) is primarily known as a voice actress and manga artist. There is no documented music career in electronic or dance music to focus on.

**Recommendation:** This artist should not be included in a DJ/electronic music tracklisting application, as they don’t have:
- Musical releases in electronic/dance genres
- Production credits
- DJ performances
- Collaborations with electronic music producers
- Contributions to electronic music culture

If you’re building a music discovery platform, I’d suggest filtering out non-musicians or artists without relevant electronic music credentials before submission.

Is there a different artist biography you’d like me to rewrite, or would you like guidance on vetting artist submissions for electronic music platforms?
