One Lone Woman; a Costume of Resolve is the 91st chapter of Hiro Mashima's Fairy Tail.

The intense battle between Erza and Ikaruga continues. Ikaruga is also a very powerful mage being able to slice Erza's swords and also three of her powerful armors namely the Heaven's Wheel Armor, Flame Empress Armor and Purgatory Armor. Then Erza decides to eliminate the distance that seperates her from others' heart, her armor. She has always been afraid and lone. But Fairy Tail taught her how to live alongside with her nakama. Now with all the strength of her comrades in her heart, she is determined to win...

Summary
Ikaruga sings a song while battling Erza, but now Erza is more serious and is determined to crush his opponent. Erza requips into her Heaven's Wheel Armor and attacks. Both mages have excellent swordsmanship and the battle is tight. Erza attacks with multiple swords, but Ikaruga was able to destroy them along with her armor using powerful spell, Yasha's Empty Flash which startles Erza.

Ikaruga attacks with her spell Garuda Flame and Erza requips to her Flame Empress Armor and she neutralizes her opponent's fire. Ikaruga is impressed with Erza speed in requiping, but was able to destroy the armor too. Seeing that Sho also is amazed saying she is a monster. Ikaruga taunts Erza into using her strongest armor, and she requips into her Purgatory Armor, but Ikaruga smashes it once more.

Erza then requips into normal clothes shocking Ikaruga and she thinks she is being understimated. Erza then says that she is not so strong, since she needs armors for protection. She was unable to save some of her nakama, remembering all her comrades. She was always crying, and she was always alone but Fairy Tail taught her the truth. What the armor did is only block the space that separates her from the others' hearts. And because of her friends love and warmth she is lost no longer and is determined to win…
