Ok so the Erza vs Kyoka fight lasted a while. How long do you guys think it would have taken Mirajane to defeat her? I understand that Mirajane was beat up at that time and had used up her magic power and stuff but lets just ignore that. Its a full power or normal state Mirajane vs Kyoka. This would also be before Mirajane got her Demon Soul: Seilah form so the only forms she could possibly use would be regular Demon Soul, Halphas, and Sitri.
